Introduction
Replacing a faulty heating element in a Tappan oven is a repair that many homeowners can handle without calling a service technician. When the bake or broil element stops glowing, the oven cannot reach the temperature you set, leading to undercooked meals and frustration. Understanding how to replace Tappan oven element safely saves money, reduces downtime, and gives you confidence in maintaining a major kitchen appliance. This guide walks you through every stage, from identifying the problem to testing the new part, while emphasizing safety and best practices.

Understanding Your Tappan Oven Element
Tappan ovens typically use two distinct heating elements: a lower bake element and an upper broil element. Both are metal coils that convert electrical energy into heat, but they operate under different conditions. The bake element runs at lower temperatures for longer periods, while the broil element endures intense, short bursts of heat. Knowing which element has failed helps you purchase the correct replacement and avoid unnecessary work.
Types of Elements
Most Tappan models use a calrod style element, a metal sheath surrounding a nichrome wire. Some newer units feature a ceramic or quartz element that heats faster and distributes heat more evenly. The part number is usually stamped on the metal bracket or printed on a label inside the oven cavity. Always verify the model number on the oven’s rating plate before ordering a replacement.
Signs of Failure
Common indicators include the oven not reaching the set temperature, visible cracks or blistering on the element surface, a burnt‑out smell during operation, or the element glowing only in sections. A multimeter test for continuity can confirm an open circuit. If the element shows infinite resistance, it must be replaced.
Tools and Materials Needed
Gather the following items before you begin: a replacement element matched to your model, a Phillips‑head screwdriver, a ¼‑inch nut driver or socket, a pair of needle‑nose pliers, a multimeter (optional for verification), work gloves, and a flashlight. Having a small container for screws prevents loss. If the oven is built into a cabinet, a step stool may be needed for comfortable access.
Safety Precautions Before Starting
Electric ovens operate on 240 V in most North American homes, which can cause severe injury or death. Always turn off the dedicated circuit breaker for the oven and verify the power is off by attempting to turn the oven on. Use a non‑contact voltage tester on the element terminals for extra assurance. Wear insulated gloves and avoid touching any metal parts until you are certain the circuit is dead. Keep the work area dry and free of flammable materials.
Step‑by‑Step Replacement Guide
Follow these ordered steps carefully. Each step includes the reason behind the action to help you understand the process.
Step 1: Disconnect Power
Locate the oven’s circuit breaker in the main panel and switch it to the OFF position. If the oven is plugged into a receptacle, unplug it. Confirm the power is off by turning the oven control knob; the display should remain dark. (See Also:How To Light Wood Pellets Pizza Oven)
Step 2: Remove Oven Racks
Slide the racks out of the cavity. This provides clear access to the element mounting brackets and prevents damage to the racks during the repair.
Step 3: Access the Element
Most Tappan ovens have a rear access panel secured by screws. Remove the screws with the Phillips screwdriver and set the panel aside. In some models the element is reachable from the front after removing the bottom drawer; consult your owner’s manual for the exact method.
Step 4: Detach the Old Element
Using the nut driver, loosen the mounting bolts that hold the element to the oven wall. Gently pull the element forward to expose the wire terminals. Note the orientation of the wires (usually a black and a red lead) and disconnect them with needle‑nose pliers. If the terminals are corroded, clean them with a wire brush before installing the new element.
Step 5: Install the New Element
Attach the wire leads to the new element’s terminals in the same configuration as the old one. Secure the mounting bolts, ensuring the element sits flush against the oven wall without bending. Over‑tightening can crack the ceramic insulator.
Step 6: Reassemble and Test
Replace the rear access panel and screws. Re‑insert the oven racks. Restore power at the breaker, then set the oven to a moderate temperature (350 °F). Observe the element; it should glow evenly within a few minutes. Use an oven thermometer to verify the cavity reaches the target temperature.
Comparison: OEM vs. Aftermarket Elements
Choosing between an original equipment manufacturer (OEM) part and an aftermarket alternative affects cost, longevity, and warranty coverage. The table below highlights key differences.
| Feature | OEM Element | Aftermarket Element |
|---|---|---|
| Price | Higher (typically $30‑$55) | Lower (often $15‑$30) |
| Fit & Finish | Exact match to factory specifications | May require minor adjustment |
| Warranty | Usually 1‑year manufacturer warranty | Varies; often 90‑day limited warranty |
| Longevity | Designed for rated cycle life | Can be comparable, but quality varies |
| Availability | Ordered through authorized dealers | Widely available online and at hardware stores |
Tips for a Longer Element Life
- Preheat the oven only when necessary; excessive cycling stresses the element.
- Clean spills promptly to prevent carbon buildup that can cause hot spots.
- Avoid using aluminum foil directly on the element; it reflects heat and can cause overheating.
- Inspect the element annually for signs of warping or discoloration.
- Use the self‑clean cycle sparingly, as the extreme temperatures accelerate wear.
Common Mistakes to Avoid
- Forgetting to verify the breaker is off – the most dangerous oversight.
- Mixing up the bake and broil elements; they are not interchangeable.
- Over‑tightening mounting bolts, which can crack the element’s ceramic insulator.
- Reusing corroded wire terminals without cleaning, leading to poor conductivity.
- Skipping the post‑install temperature verification, which can hide a faulty connection.
Troubleshooting After Replacement
If the oven still fails to heat correctly after installing a new element, check the following: ensure the circuit breaker is fully engaged, verify the wire connections are tight and on the correct terminals, test the new element for continuity with a multimeter, and inspect the oven’s temperature sensor (thermistor) for damage. A faulty control board can also mimic an element failure; if all else checks out, consult a professional for board diagnostics. (See Also:What Oven Temp To Cook Butternut Squash)
Frequently Asked Questions
How do I know which element is bad?
Set the oven to bake and watch the lower element; if it does not glow, the bake element is likely faulty. Set to broil and observe the upper element. A multimeter continuity test on each element provides a definitive answer.
Can I replace the element without turning off the breaker?
No. Working on a live 240 V circuit is extremely hazardous. Always disconnect power at the breaker and verify with a voltage tester before touching any wiring.
What if the new element does not fit the mounting holes?
Double‑check the part number against your model. Some aftermarket elements have slightly different bracket spacing; you may need to enlarge the mounting holes with a drill or order the exact OEM part.
How long does a typical Tappan oven element last?
With normal use, a bake element lasts 8‑12 years, while a broil element may last 5‑8 years due to higher heat cycles. Regular cleaning and avoiding foil contact can extend life. (See Also:How Long French Fries In Oven)
Is it worth repairing an older Tappan oven?
If the oven is otherwise in good condition and the repair cost is under $100, replacing the element is usually economical. For units over 15 years with multiple failing components, a replacement oven may be more cost‑effective.
Conclusion
Replacing a Tappan oven element is a straightforward DIY task when you follow a clear, safety‑first process. By identifying the faulty element, gathering the right tools, and carefully executing each step, you restore full heating performance without the expense of a service call. Remember to choose a quality replacement—whether OEM or a reputable aftermarket part—and to test the oven thoroughly after installation. With proper maintenance and the tips outlined above, your new element will provide reliable service for years to come. Now that you know how to replace Tappan oven element safely, you can tackle this repair with confidence and keep your kitchen running smoothly.
