Introduction
Yes, many electric ovens have replaceable heating elements, and a failed element is often less complicated to repair than other oven faults. Knowing how to replace heating element in oven can restore normal baking, broiling, and heat distribution while avoiding the cost of a service visit. However, an oven simultaneously heats to high temperatures and operates on a mains-voltage electrical supply, so basic DIY experience and strict safety precautions are essential.
This guide explains how to identify a faulty element, compare replacement parts, disconnect and install the new component, reconnect its wiring, and test the oven. It also explains when calling a technician is safer than continuing the repair.

Can You Replace Heating Element in Oven?
You can usually replace a heating element in an electric oven if the model has a conventional exposed element. The element is typically located at the bottom of the oven cavity for baking and sometimes at the top for broiling. Many elements are held in place by two screws and connected to a terminal block, making the physical replacement relatively straightforward.
Replacing the element does not necessarily mean rewiring the oven. In many models, the new element has the same plug-in terminals, and you only move the existing high-temperature wires to the corresponding posts. Nevertheless, you must work safely because the terminal block can remain connected to the household circuit even when the oven is switched off.
A replacement is appropriate when:
- The oven reaches normal temperature but food remains uncooked or cooks unevenly.
- One of the oven’s heating elements is visibly cracked, blistered, displaced, or visibly damaged.
- A continuity test confirms that the element is open-circuit.
- The replacement matches the oven manual in shape, dimensions, wattage, voltage, mounting method, and connection type.
The repair may be unsuitable when heat is absent throughout the oven, the control display shows an error code, the breaker trips, or the terminal block and wiring show heat damage. Those symptoms may point to a control board, relay, thermostat, thermal fuse, wiring fault, or another component rather than a simple failed element.
Gas ovens do not use an electric heating element in the same way. If you have a gas oven and suspect an igniter, burner, or thermostat problem, follow the appliance manual or consult a qualified gas-appliance technician.
Diagnose the Problem
Before buying a part, confirm that the heating element is the actual cause. First use the oven controls as described in the manual. A bake cycle may take several minutes before the chamber reaches temperature, so a short test immediately after switching it on is not always meaningful.
Look for these clues:
- No heat from one position: If the lower element heats but the upper broil element does not, the problem is probably limited to the upper element. The reverse also applies to a lower bake element.
- No heat from either element: The fault may involve the element selection, control system, thermal switch, relay, circuit breaker, or supply wiring.
- Uneven cooking: A damaged or incorrectly installed element may produce heat in one area, but thermostat calibration or airflow problems can cause similar symptoms.
- Visible damage: A cracked element, separated metal sheath, severe discoloration, or a loose element can confirm physical failure.
- Repeated breaker trip: Stop testing and have the oven inspected. A short circuit or damaged wiring should not be treated as an ordinary element replacement.
If both elements are cold, check the settings and make sure the oven is receiving power before removing panels. With the oven disconnected, a technician or competent DIY user can test the element for continuity. An intact heating element normally allows current to pass across its two terminals. An open-circuit result indicates failure. Follow the appliance manufacturer’s testing instructions because acceptable resistance values vary by model.
Also verify that the oven has not activated a control lock, delay start, Sabbath mode, or other setting that prevents the selected element from operating.
Types and Shapes of Heating Elements
Oven elements are not interchangeable simply because they look similar. Lower bake elements, upper broil elements, convection elements, and compact portable-oven elements can all differ in length, mounting position, wattage, resistance, and connector arrangement.
| Element type | Typical location | Common function | Replacement consideration |
|---|---|---|---|
| Lower bake element | Bottom of the oven cavity | General baking and cooking | Must match the original shape, wattage, mounting tabs, and terminals |
| Upper broil element | Top or upper rear of the cavity | Broiling, browning, and some heating cycles | May have one or two elements and may connect through a separate terminal block |
| Convection bake element | Lower area or behind a rear panel | Even, fan-assisted cooking | Access may require removal of additional covers |
| Portable-oven element | Removable countertop oven | Depends on the model | Countertop models often use different mounting hardware and electrical ratings |
Some ovens also have a concealed ceramic infrared heater. It should be serviced using the model-specific instructions because it usually requires additional disassembly and is not interchangeable with a exposed metal element.
Use the model number and serial number, not just the oven’s visible brand name, to identify the correct replacement. A close dimensional match is still not enough: a replacement with the wrong wattage may overheat the surrounding oven cavity or fail under normal load.
Safety Before You Begin
Oven replacement parts operate at high heat, while the terminal block may expose 120- to 240-volt current depending on the appliance. Treat every part of the job as potentially energized until you have verified that power is disconnected.
- Read the appliance installation and service instructions before removing any panels.
- Switch the oven off at the controls and unplug it if it is a countertop model.
- For a built-in or freestanding electric range, switch off the appropriate circuit breaker. If uncertain, switch off the main breaker.
- Wait until the oven is completely cool. The cavity and element can remain hot for a considerable time.
- Confirm disconnection with an appropriate voltage tester. A non-contact tester can provide an initial indication, but a properly rated multimeter is more reliable for confirming the absence of voltage.
- Use insulated tools, keep your hands dry, and never work on a wet floor.
- Do not bypass, modify, or tape over an electrical safety device.
Terminals that show melting, discoloration, looseness, or a burnt odor must be inspected before installing a new element. The damage may be a result of the original failure, but it can also mean that wires or connectors have become overheated or too loose. Continuing to use compromised connectors can cause arcing, a fire, or another failure.
Some oven cavities have porcelain or coated surfaces that can chip if tools are forced against them. Work gently and avoid placing metal tools where they can scratch the enamel.
Tools and Replacement Parts
The tool list varies by oven, but most conventional element replacements require:
- Phillips-head screwdriver
- Flat-blade screwdriver, if required by the terminal block or panel fasteners
- Nut driver or socket wrench, if the element uses nuts
- Needle-nose pliers for accessible wiring, where needed
- Multimeter or continuity tester
- Non-contact voltage tester for an initial power check
- Work gloves and eye protection
- Camera or a prepared note for recording wire positions
Before purchase, verify the original element’s voltage and wattage rating, physical length, terminal spacing, mounting-hole pattern, and connector style. Exact part fit is particularly important for an electric range because its supply may be 240 volts. A lower-wattage element may function but cycle for long periods, while an incorrectly specified element can create a safety or overheating problem.
High-temperature replacement wire and manufacturer-approved terminals may be needed if the existing wiring or connectors are damaged. Ordinary household wire, a crimped splice, or a terminal that cannot firmly grip the post is not an acceptable substitute.
Replacement elements are commonly available through appliance-parts suppliers and authorized service channels. When possible, use a new element and any new specified thermal fuse or gasket supplied as a service kit.
Step-by-Step Replacement Guide
1. Prepare the oven
Move the oven’s contents, racks, and removable trays away from the work area. If the unit is a freestanding range, protect the floor and move nearby objects before pulling it forward, if the installation instructions permit. Built-in ovens may require opening the cabinet door and removing trim or mounting screws. Do not lift or support the appliance in a way that could damage its electrical or gas connections.
2. Disconnect and verify power
Turn the oven off and disconnect the electrical supply. For a built-in electric oven or range, identify the correct circuit breaker and switch it off. Unplug a countertop oven. Allow the oven to cool fully, then check for voltage at the element terminals according to the instructions for your meter.
Do not rely only on the red oven light being off or the display being blank. Some internal circuits can remain energized even when the controls appear inactive.
3. Access and remove the old element
Remove any storage drawer below a range if the model requires it. Unscrew the element retaining screws or nuts from inside the oven cavity. If a metal or fiberboard cover conceals the connections, remove the specified cover screws and set the cover aside carefully.
Before touching the wiring, photograph or make a simple diagram showing which conductor is attached to each terminal. Disconnect the wires at the element posts using the appropriate screwdriver or pliers. High-temperature spade connectors may require gentle rocking rather than pulling; do not twist the posts or damage the terminals.
Once disconnected, lift or slide the element out of its mounting brackets. If it does not move easily, verify that all nuts or screws have been removed. Do not force the element against the side walls, as the mounting legs or ceramic insulators may break.
4. Compare the new part
Before installing the replacement, compare it directly with the removed element. Check the model number, length, width, mounting holes, terminal orientation, wattage, and voltage. Confirm that the new element is designed for that exact oven position. Upper and lower elements can look almost identical while having different ratings or terminal arrangements.
If the new element came with packaging, remove all ties and protective material. Keep screws and insulating washers organized so nothing is left loose inside the cavity.
5. Install the new element
Position the new element so the element’s bending channel faces the oven interior and the mounting legs align with the brackets. Do not change the element’s shape by straightening or sharply bending the metal sheath. Some manufacturers specify a particular orientation to distribute heat and maintain clearance from the cavity.
Seat the element squarely and reinstall the original retaining screws or nuts. Tighten them firmly enough to hold the element in place, but avoid excessive force that could crack porcelain supports or deform the element. Replace any specified insulating washers or gaskets, especially if they were damaged or removed during disassembly.
6. Reconnect the wiring
Return each high-temperature wire to the exact terminal recorded before removal. If the appliance manual identifies the terminals, follow that diagram rather than relying only on wire color. Make sure each connector is fully seated and mechanically secure, with no exposed conductor extending beyond the terminal.
Replace heat-damaged connectors or wires with the type approved for appliance service. Do not twist unrelated wires together, use an alligator clip, or create a temporary soldered connection. A loose terminal can arc even when the element is operating normally.
7. Restore the oven
Reinstall any access cover, storage drawer, cabinet trim, and oven door according to the service instructions. Make sure no screw, washer, wire, or tool has been left inside the oven. Replace a damaged door gasket before operating the appliance if it does not seal correctly.
With the circuit still off, inspect the work once more. Check that the element is centered, the wires are clear of moving parts, and no part contacts the metal cavity where it should remain insulated.
8. Perform an initial check
Restore power and set the oven to a normal bake cycle. Many ovens have a delayed start, and the element may cycle on and off during preheating rather than glow continuously. Watch the oven through the glass for several minutes and confirm that the installed element heats evenly.
Stop the oven and switch off the breaker immediately if you notice smoke, sparking, a burning plastic smell, unusual arcing, a loose element, or a breaker trip. If the replacement part was correct and installed properly, the new element should begin producing controlled heat without these symptoms.
Understanding the Wiring Connections
On many ovens, the element connector block has two screws with blades secured beneath them. Loosening the screws releases the wires from the terminal block; tightening them captures the blades. One element may share a block with other components, so read the diagram and observe each original connection rather than assuming every screw serves the element you removed.
Some oven designs plug elements into a connector instead. In that case, pull the plug straight out according to the manufacturer’s instructions and inspect it for heat damage. A replacement element that uses a different connector is not compatible with the existing socket.
On a 240-volt electric range, low-voltage control wires and line-voltage element wires may be located near each other but are not electrically interchangeable. The oven’s wiring diagram is the authoritative source. If the terminal block is part of a plug-in harness and shows no damage, the new element should connect in the same way as the old one.
If the original element failed because its connector loosened, installing only the element may not solve the problem. Correct the cause by replacing damaged terminals, crimped high-temperature leads, or burned wires with the specified parts.
Testing the New Element
A successful replacement should restore the expected heat in the selected cooking mode. Let the oven preheat fully and compare its behavior with normal use. It is normal for an element to cycle because the thermostat controls the oven temperature.
Before operating the oven, make sure the empty cavity contains no loose objects, screws, plastic packaging, or disconnected wires. Place protective cookware on the racks if the manual recommends it during an initial test.
Check for these results:
- The correct element activates in bake or broil mode.
- The replacement element does not touch the oven walls or brackets.
- The temperature display behaves normally.
- No sparks, smoke, or persistent electrical odor appear.
- The breaker remains on.
- The oven reaches and maintains temperature without running continuously.
If the oven remains cold, the control may be selecting a different element or the selected element may still have a circuit-path problem. Use the appliance’s diagnostic procedure or have a technician test the terminals, thermostat, thermal fuse, control board, and supply connections. A replacement element that draws no current is not proof that every related component is working.
Troubleshooting Comparison
| Symptom | Possible cause | Recommended action |
|---|---|---|
| Lower element stays cold, but upper element heats | Failed lower element or disconnected lower-element wiring | Verify the model-specific controls, inspect the terminal block, and test the lower element |
| Neither element heats | Breaker, supply connection, thermal fuse, control, thermostat, or wiring fault | Do not assume the element is defective; test the oven’s power and control circuit |
| Element glows but food stays uncooked | Temperature-sensor problem, severe door leak, or inaccurate thermostat | Verify an oven temperature with an independent thermometer and inspect the door seal |
| Breaker trips during operation | Short circuit, damaged wire, loose terminal, or moisture contamination | Turn off power and obtain a qualified electrical or appliance diagnosis |
| Wire or terminal is discolored | Loose or overheated connection | Replace the damaged high-temperature lead and terminal with approved service parts |
Common Mistakes to Avoid
- Buying by appearance alone: Two elements may fit physically but have different wattage, resistance, or terminal spacing.
- Working without cutting power: The oven control may be off while the element terminals remain electrically live.
- Touching the element while it is hot: Let the oven cool fully and handle a damaged element carefully because metal edges may be sharp.
- Failing to record wire positions: Photograph the connections or label them before disconnecting anything.
- Overtightening the element: Excess force can damage porcelain insulators, mounting brackets, or the element’s legs.
- Using ordinary electrical wire: Household wire and general-purpose connectors are not designed for sustained oven temperatures.
- Leaving covers or screws inside the oven: Loose metal can contact the element and damage it or create a hazard.
- Ignoring a recurring breaker trip: A new element will not correct a short circuit or damaged terminal block.
- Forcing a concealed element out of position: Hidden heating elements may require removal of the oven from its installation.
Tips and Best Practices
- Record the oven’s model and serial number before ordering a replacement.
- Take a clear photograph of the old element, wiring layout, and mounting points.
- Keep screws in labeled groups so each cover returns to the correct position.
- Buy an exact-match element from a reputable supplier, even if a similar universal-looking element is available.
- Inspect the new element before installation and never use one with a cracked sheath or bent terminal.
- Check the terminal block for discoloration, looseness, or heat damage every time you replace an element.
- Use a temperature test oven independently if foods have seemed undercooked or overcooked after the repair.
- Run an empty bake cycle after installation and remain nearby during the first test.
- Let the oven cool before cleaning, and avoid abrasive pads or harsh chemicals on the enamel cavity.
- Keep the installation manual and service diagram accessible for future maintenance.
Do not place foil, parchment, trays, or cookware against a exposed heating element during operation. Contact can create hot spots, restrict heat flow, or damage the element. For protective liners, use only products approved for the specific oven and install them exactly as directed.
When to Call a Technician
Call an appliance technician or qualified electrician if the breaker repeatedly trips, the terminal block is damaged, the terminal block is not loose, or the replacement wire becomes hot without normal element operation. Persistent burnt odors should be investigated before the oven is used again.
Professional help is also sensible when the oven is built into a cabinet and cannot be safely accessed, when the element is concealed, or when the model requires the oven to be removed from the gas or electrical connection. If the oven is powered by a gas line, do not disconnect fittings yourself unless you are specifically trained and authorized to do so.
A technician is the safer option when you are uncertain how to test for voltage, cannot identify the correct terminal arrangement, lack tools rated for the appliance, or see signs of water intrusion, arcing, or heat damage around the control board. Repairing the element itself is not worth risking a shock, gas leak, fire, or damage to the appliance’s wiring system.
Frequently Asked Questions
How much does it cost to replace an oven heating element?
Replacement elements commonly cost from roughly $20 to $100 or more, depending on the oven brand, element type, and whether you need a terminal, gasket, or thermal fuse. Labor adds another cost when a technician performs the work. The main expense is often shipping or sourcing the correct part, so identifying the full model number before ordering can prevent an incorrect purchase.
Can I replace an oven element with a different brand?
You should use a part designed for the exact oven model and position, not merely the same shape. The replacement must have the correct voltage, wattage, resistance, physical dimensions, mounting pattern, and terminal arrangement. A manufacturer-compatible aftermarket part can be suitable if its specifications meet the appliance manual’s requirements.
Do I need to turn off the breaker before replacing the element?
Yes. Turn off the appropriate circuit breaker or unplug the countertop oven, and verify that the terminals are de-energized before removing wiring. The control being switched off does not guarantee that the element is safe to touch electrically. If you cannot confidently identify and verify the supply, stop and obtain qualified assistance.
How do I test an oven heating element for continuity?
Disconnect the element and use a multimeter set for the appropriate resistance or continuity function. Touch the probes to the two element terminals. An intact element should show continuity, although the resistance reading can vary significantly by model. An open or infinite reading often indicates a broken element. Never test resistance while the element is connected to power, and follow the appliance service instructions when accessible.
What if the new element looks different from the old one?
Stop and verify the part number and oven model. Some ovens use a lower element, upper broil element, convection heater, or concealed ceramic element that can differ in appearance and mounting. If the replacement does not match the manual, do not modify the oven or alter the terminals to make it fit.
What should I do if the oven still does not heat after replacing the element?
First confirm that the oven is in the correct bake or broil mode and that its control lock or delay setting is not interfering. Then check for a tripped breaker or control error. If power and settings are normal, the fault may be in the thermostat, temperature sensor, thermal fuse, relay, control board, or wiring. Do not repeatedly replace elements until the electrical path has been tested.
Conclusion
Can You Replace Heating Element in Oven? For many conventional electric ovens, the answer is yes, provided you identify the exact replacement and follow the appliance’s safety and wiring instructions. The main tasks are to disconnect the power, remove the damaged element, compare the new part, reconnect the terminals securely, reinstall the covers, and test the oven carefully.
The most important safety step is to treat the terminal block as live until power has been physically disconnected and verified. Never ignore smoke, arcing, a burning odor, heat-damaged wiring, or a breaker trip. If the fault affects both elements, involves the control system, or requires access to concealed components, call a qualified technician.
With the correct part and careful workmanship, replacing a failed heating element can restore reliable oven performance and extend the useful life of the appliance.
