Introduction
A Tappan oven that does not heat normally often has a failed bake or broil element. Common signs include an oven that stays cold, uneven cooking, food that takes too long to brown, visible cracks or burned areas in the element, or a broiler that no longer becomes hot. Understanding how to replace a Tappan oven element can restore normal heating and eliminate an unnecessary full appliance replacement.
Tappan ovens were manufactured in many sizes, styles, and eras, and their elements are not interchangeable by appearance alone. The correct replacement must match the appliance voltage, wattage, physical dimensions, terminal arrangement, and intended heating function. The model and serial numbers are therefore the essential starting point.
This guide explains how to identify the correct part, disconnect an element safely, install the replacement, reconnect its terminals, and test the oven. It also covers hidden elements, electrical checks, troubleshooting, and mistakes that can cause a new element to appear faulty.

Recognizing a Failed Oven Element
The heating element is usually the most obvious electrical component inside the oven cavity, but not every heating problem comes from the element itself. Confirm the symptoms before ordering a part.
- No heat at all: The oven reaches its preheat setting but remains cold.
- Slow heating: The oven takes substantially longer than usual, or food remains pale and unfinished.
- Uneven heating: One side of a baking sheet stays noticeably cooler.
- Limited heating: Broiling works but baking does not, or the opposite occurs.
- Visible damage: The element has a crack, break, blister, burned section, or unusually large gap.
- Physical movement: A bake element is hanging loose or no longer seated in its support brackets.
A glow that differs from normal can also indicate damage, although not every bake element glows visibly. Some elements remain dark or glow only briefly. Temperature behavior and electrical testing are more reliable than appearance alone.
Before replacing the element, rule out simple causes such as an incorrect oven mode, delayed electronic heating, a severely worn door gasket, blocked air vents, or a temperature sensor issue. If the oven does not heat in any mode and shows an error code, the control system may require diagnosis before the element should be replaced.
Safety Before You Begin
Oven elements operate on a high-voltage, high-current circuit. Even a small visible defect does not make energized terminals safe to touch. Follow these precautions before beginning:
- Disconnect the electrical supply. Switch off the oven, shut off the range circuit at the breaker, and confirm that power is disconnected before removing a panel. Do not rely only on the oven control or clock.
- Allow the oven to cool completely. The cavity, element, racks, side walls, and terminal area may remain hot for a long time after use.
- Protect the range finish. Place a folded towel or protective material on the cooktop or range top if panel screws could fall into the oven cavity. Do not block element vents during the work.
- Avoid sharp impacts. Bake elements can be brittle, especially after years of heating. Do not strike the element housing, force it around supports, or use it as a handhold.
- Keep liquids away from electrical parts. Do not pour water into the terminal compartment or wash a control area while it is connected to power.
- Stop if the circuit trips. If a newly installed element repeatedly trips the breaker or creates a burning smell, disconnect power again and investigate the wiring, insulation, mounting, and part compatibility.
If the Tappan appliance has a gas connection as well as an electric oven, follow the appliance manual for gas shutoff and access procedures. Do not loosen, move, or disturb sealed gas lines while servicing the oven element.
Finding the Model and Correct Tools
The model number is more important than the oven’s apparent size or brand styling. Tappan products may be associated with different manufacturers, and visually similar ovens can use different heating assemblies. Locate the model and serial number on a plate inside the door frame, under the control panel, on a door rail, or on the range body. Older models may place the information inside a storage drawer or beneath the oven door.
Use the model number to find the appliance manual and original parts diagram. Compare the replacement listing against the existing element. Confirm all of the following:
- Correct bake, broil, upper, or lower function
- Required voltage and wattage
- Overall length, width, and mounting flange dimensions
- Terminal and lead configuration
- Element shape, bracket positions, and attachment method
- Manufacturer or original-equipment part number
A high-quality replacement may have slightly different resistance from the original element. Exact resistance can vary with temperature and design, so use the service manual for an exact limit. When in doubt, the manufacturer’s listed compatible part is safer than a visually similar substitute.
Common tools include a Phillips screwdriver, straight screwdriver, socket or nut driver, pliers, work gloves, a flashlight, and a multimeter. A multimeter is optional if the failed element has unmistakable physical damage, but it helps distinguish an open element from a control, wiring, or temperature-sensor problem.
Understanding Bake, Broil, and Hidden Elements
Some Tappan ovens use one element, while others use separate upper and lower elements. Knowing the installed system prevents ordering the wrong part or replacing a healthy component. (See Also:How To Unlock Electrolux Oven Door)
| Element type | Heating purpose | Typical location and behavior | Replacement consideration |
|---|---|---|---|
| Bake element | Provides steady heat for general cooking | Usually at the lower rear or lower portion of the oven; may not glow noticeably | Match voltage, wattage, dimensions, and terminal arrangement |
| Broil element | Produces intense, concentrated heat from above | Usually near the top and more likely to glow during operation | Verify that the replacement is specifically a broil element, not a bake element |
| Upper or lower bake element | Separates top and bottom heating | Two-element systems use distinct connectors and operating controls | Do not interchange upper and lower elements unless the parts diagram approves it |
| Hidden bake element | Protects and conceals the bake element beneath the oven floor | Requires removal of the floor liner or concealed bake cover | Replace the complete concealed assembly and restore all seals and supports correctly |
Some concealed assemblies include both the element and a protective bottom panel. A replacement that is only the bare heating element may not restore the original heat circulation or structural protection.
How to Replace a Tappan Oven Element?
Use the following process only after confirming that the replacement part is correct and the oven is disconnected from power. Procedures vary by model, so treat the service manual as the final authority when it differs from general instructions.
Accessing and Removing the Old Element
- Verify the replacement before starting. Compare the new element with the removed or accessible original. Check the part number, wattage, lead length, connector style, and mounting points. Do not install a part solely because it fits loosely.
- Remove the oven racks. Pull the racks forward and lift them out carefully. If a rack support must be moved, note its position before removal.
- Remove the oven or rear access panel. Depending on the model, this may require removing the door, control-panel trim, rear panel, side screws, or a floor cover. Store screws by location because different fasteners may have different lengths.
- Expose the wiring. Move any wiring or insulation that conceals the element terminals. Photograph the original wire connections before disconnecting anything. A clear image can reveal which lead belongs to which terminal and how the wires are routed.
- Disconnect the leads in the correct order. Terminal styles vary. A spade connector slides onto a male terminal, while a ring or bare wire may attach beneath a screw. Pull straight off a terminal rather than pulling the wire. If a screw clamps a bare lead, loosen it carefully without stripping the screw.
- Support and lift out the element. Remove any retaining screws, brackets, or floor clips that prevent movement. Lift the element without twisting sharply. If it is fixed to the floor with screws or hidden beneath a bake plate, remove only the hardware specified by the service documentation.
Do not assume that all visible wires are element leads. A temperature-sensor wire may be a thin, insulated cable, and a ground wire may be connected separately. The replacement element should normally have only its two heating leads unless the assembly includes another component.
Inspect the exposed cavity after removal. Look for melted insulation, soot around terminals, loose brackets, damaged wiring, or signs that the element overheated because of a blocked vent. If the terminal block is burned or brittle, replacing the element alone may not solve the problem.
Installing and Connecting the New Element
- Keep the breaker off. Leave the oven disconnected while positioning and securing the new element.
- Place the element in the original position. Route the leads through the same channels and around the same clips as the old element. This prevents pinching, kinking, contact with sharp metal, or interference with racks and doors.
- Reinstall supports without overtightening. Tighten mounting screws until secure, but avoid crushing fragile element connections or stripping the oven liner.
- Connect each lead correctly. Slide a fully seated spade connector onto its matching terminal. If the old connection used a ring terminal, place the ring beneath the terminal screw and tighten it securely. For a bare-wire connection, keep all strands under the clamp with no loose strands touching the terminal housing.
- Inspect the connections again. Confirm that insulation is not pinched, connector metal is not touching the cabinet, and no wire is routed near a sharp edge or heating area. A connector must not be installed backward if it has keyed features.
- Reassemble the oven. Replace the floor liner, access panel, trim, door, racks, and any retainers removed earlier. Confirm that the new element does not touch the oven door, rack supports, fan shroud, or rear panel.
For a hidden element, reinstall the bottom liner and concealed heating assembly in the manufacturer’s specified sequence. Missing screws, misaligned gaskets, or an incorrectly positioned floor panel can affect airflow, heat distribution, and door closure.
Reconnecting and Testing the Oven
Before restoring power, visually inspect the entire installation. Every screw should be present, wires should be secured, and the element should sit level without strain on its terminals. Replace any damaged insulation before proceeding.
If the old element can be tested while removed, disconnect the oven from power and measure between its two electrical terminals with a multimeter set to resistance. A functioning cold heating element normally shows finite resistance rather than an open circuit. A reading of zero or infinite resistance can indicate a failed element, although the appliance’s other circuits and control components must be checked separately. Compare the result with the manual when an exact resistance specification is available.
A new element should also show continuity or a stable resistance value when cold. Do not use a low-voltage continuity test to prove that an element can safely operate under full oven load.
Restore the breaker after the panel and wiring are fully reassembled. Set the oven to bake and observe it for the first several minutes. Listen for the relay or control-system operation and watch for normal heat near the element or at the oven floor. Some models delay heating for several minutes while the control checks the system or enters a learning process.
Allow the oven to complete a full preheat cycle. Place an oven thermometer in the center of the cavity and compare the displayed and measured temperatures after at least 30 minutes. The element may not glow, but the oven should heat consistently. If the display indicates that preheat is complete, compare the temperature with the expected oven setting, allowing for normal measurement differences.
Test baking and broiling separately when the appliance has multiple elements. Use a short, supervised test rather than leaving an unattended oven at a high temperature. Check for burning odors, unusual sounds, repeated breaker trips, error messages, or one zone failing to heat.
Troubleshooting After Replacement
A replacement element does not heat when the fault was actually caused by another component. Use a logical sequence rather than repeatedly disconnecting the new element.
If the oven still does not heat
- Confirm that the correct cooking mode and temperature were selected.
- Wait through any electronic delay, control reset, or temperature-calibration process specified in the manual.
- Check that the breaker and outlet connections are secure.
- Verify that the element leads were connected to the correct terminals.
- Inspect the temperature sensor and its connector. A shorted sensor can tell the control that the oven is already hot.
- Check for an open thermal fuse, thermal cutoff, relay, or control board output where the model uses them.
- Compare the new element’s cold resistance with the manual or original specification.
If only baking or broiling fails
If the bake function works but broiling does not, confirm that the oven has a separate broil element and that it is installed in the correct position. Reverse the diagnosis if only the bake element fails. On electronically controlled models, check whether the operator interface is calling for the element that was replaced. Some control systems assign different circuits to upper, lower, and rear elements, so a physically correct part may still be connected to the wrong output. (See Also:How To Make Frozen Bacon In Oven)
If the oven heats unevenly
An uneven bake can be caused by a worn door gasket, blocked vents, heavy bakeware, incorrect rack placement, a failed heating element, or a temperature sensor problem. Compare the top and bottom of the oven. If one side is consistently cooler, inspect element alignment and ensure that the element is not being obstructed. Hidden elements also require correct installation of their protective panel, because a bent or missing panel can disturb airflow.
If the breaker trips
Disconnect the oven immediately. Repeated breaker trips can result from a damaged element, exposed conductor, loose terminal, incorrect wiring, an internal wiring fault, or a short to the oven cabinet. Do not continue testing by repeatedly resetting the breaker. Allow the appliance to cool and have the installation or wiring checked before using it again.
If the element does not glow
A visible glow is not a universal test. Many lower bake elements glow faintly, briefly, or not at all, especially on models with concealed elements or high-voltage ignition systems. An upper broil element is more likely to glow during operation. If the oven reaches temperature in the expected time, lack of visible glow alone does not indicate failure.
Tips and Best Practices
- Use the exact compatible part. Match part numbers and electrical ratings, not just the oven dimensions.
- Photograph the original wiring. A photograph prevents confusion between element leads, sensors, grounds, and other wires.
- Keep the oven cavity clean. Grease and food debris can burn onto the element and reduce performance. Clean only after the oven is cool and use a product approved for oven surfaces.
- Do not use the self-clean cycle until normal operation is confirmed. Some older Tappan models use the bake element during cleaning. Follow the manual’s replacement and cleaning guidance, and avoid high-temperature cleaning if the element has not been tested.
- Maintain airflow. Keep vents and the area around the element free of foil, cookware, and baked-on residue.
- Check the door gasket. A torn or compressed gasket allows heat loss and can produce longer preheating or uneven cooking after the element is replaced.
- Expect a new element to change resistance slightly. A modest difference from an aged original is normal if the replacement matches the design and specifications.
- Test before loading food. Complete an empty, supervised preheat cycle and verify temperature before relying on the oven for a long meal.
Common Mistakes to Avoid
- Installing a visually similar element: Similar dimensions may hide differences in wattage, voltage, terminal orientation, or heating area.
- Leaving the breaker on: Oven terminal blocks can remain energized even when the range clock is off. Always disconnect and verify the circuit.
- Pulling wires instead of connectors: This can damage the insulation or terminal and create an intermittent connection.
- Reversing or loosening terminal connections: Loose terminals can arc, overheat, trip the breaker, or stop the oven from recognizing that the element is present.
- Pinning wires beneath a sharp panel edge: This may not be visible until the element heats, at which point the insulation can short out.
- Overtightening element screws: Excess pressure can create stress at fragile connections or damage the oven liner.
- Ignoring damaged terminals: A new element installed onto burned, loose, or discolored connections may fail immediately or create a fire risk.
- Replacing every component at once: Replacing the element, control board, sensor, and wiring without diagnosis makes the actual fault harder to identify.
- Assuming no glow means failure: Some functioning bake elements remain dark. Measure temperature and use electrical specifications instead.
- Skipping model-specific instructions: Tappan oven designs vary considerably. Service instructions for a different model may result in incorrect routing, grounding, or panel reassembly.
Frequently Asked Questions
Are all Tappan oven elements the same?
No. Tappan ovens may use different bake elements, broil elements, upper and lower assemblies, or concealed elements. Voltage, wattage, size, mounting brackets, and terminal arrangements must match the model’s parts diagram.
How can I know whether the element is actually bad?
Visible cracking or a broken heating section is a strong sign, but an electrical test is often more reliable. With the oven disconnected, measure resistance across the element’s two terminals. An open reading commonly indicates failure. However, a new element will not solve an unpowered circuit, failed control relay, open thermal cutoff, or defective temperature sensor.
Should an oven element glow?
Broil elements commonly glow bright red or orange, while many bake elements glow faintly, briefly, or not at all. Element design and visibility also matter. Confirm heating with an oven thermometer and a complete preheat cycle rather than relying on visible glow alone.
Can I replace a hidden Tappan bake element?
Only if the manufacturer’s documentation identifies it as a serviceable assembly. A hidden element may sit beneath a removable or permanently bonded floor panel, making replacement more involved than a conventional exposed element. Do not cut, pry, or remove a bonded liner without the correct replacement procedure. If the original part cannot be obtained, confirm whether a complete concealed element and bake plate are available.
Is replacing a Tappan oven element safe to do yourself?
It can be safe when the correct manual is available, the breaker is properly disconnected, and you are comfortable with basic wiring and appliance repair. A concealed element, burned terminal block, complex electronic control, repeated breaker trips, or uncertainty about safe disconnection is a strong reason to use an appliance repair professional.

Why does a new Tappan oven element fail to heat?
Common causes include an incorrect control mode, an electronic heating delay, a loose or incorrectly connected lead, a failed temperature sensor, an open thermal cutoff, a control-board output problem, or a damaged wiring harness. Verify the element itself and then diagnose the circuit supplying it. If the breaker trips, stop testing and disconnect the appliance immediately.
How long does the replacement take?
For an experienced person working on an exposed element, the actual replacement may take about 30 to 90 minutes after the oven is fully cool. First-time repairs can take longer because of model identification, hidden fasteners, access panels, terminal types, or unexpected wiring problems.
Can I use the self-cleaning cycle after changing the element?
Use the oven normally and verify that both bake and broil functions work first. Then follow the appliance manual for self-cleaning instructions. If the manual specifies a waiting period or special procedure, follow it. Keep the oven empty during an initial supervised test and never assume a replacement restores every part of a self-cleaning system.
Conclusion
Knowing how to replace a Tappan oven element can restore normal cooking performance when the element is the failed component. The key is to identify the exact model, order a compatible bake or broil part, disconnect power completely, follow the correct access and wiring procedure, and restore the element’s original position before testing.
A new element may not solve the problem if the actual fault lies in a temperature sensor, control system, thermal cutoff, terminal block, or wiring harness. Test the installed part, inspect the electrical connections, and verify the oven temperature under supervision. With the correct part and careful installation, a Tappan oven can return to dependable, even heating without unnecessary appliance replacement.
