The bake element is the main heat source in an electric oven. It fails open, often with a visible break or blister, and the oven stops heating while the stovetop keeps working.

Oven Repair: No Heat, Uneven Baking and Door Problems
Diagnose an oven that won't heat, bakes unevenly, runs hot or cold, or has a door that won't close. Test the elements, temperature sensor and control board.
Ovens fail in a small number of predictable ways. An electric oven that will not heat usually has a broken bake element or a failed control relay; a gas oven usually has a weak igniter or a dirty flame sensor. Uneven baking with a working element points to a temperature sensor, a failing fan in convection models, or a door that does not seal.
The control board is the most over-diagnosed part in an oven. Test the element for continuity and the sensor for resistance first — both are inexpensive and easy to reach. Only after those check out does the board become the likely cause.
Symptoms this guide covers
- Oven does not heat at all
- Bakes unevenly or burns one side
- Oven runs too hot or too cold versus the dial
- Door will not close flush or springs back open
- Self-clean cycle locks the door or errors out
- Error code on the display
Test order before you replace anything
- Test the bake element for continuity and look for a visible break or blister
- Test the oven temperature sensor resistance and compare it to the service sheet for the model
- For gas ovens, watch the igniter glow and confirm the burner lights within the normal time
- Inspect the door hinge, spring and gasket; a door that does not seal ruins temperature stability
- Check the control board for burnt relay contacts or a failed solder joint before replacing it
Parts involved in oven repair
The broil element sits at the top of the cavity and provides high heat for broiling. A failed broil element leaves the oven usable for baking but unable to broil, and it is tested the same way as the bake element.
The sensor reports cavity temperature to the control board. A drifting sensor causes over- or under-baking, uneven results and temperature error codes even though the elements still work.
Hinges hold the door against the gasket and control how it opens. A worn hinge lets the door sag, which breaks the seal and causes uneven baking, or makes the door spring shut.
The igniter both sparks the burner and, on many gas ovens, proves the flame to the safety valve. A weak oven igniter glows but draws too little current, so the valve never opens and the oven never lights.
The control board runs the cycle and switches the loads. It is the most over-diagnosed part in appliance repair: failed elements, sensors, switches and pumps cause most 'board' symptoms.
What drives the cost
- Electric versus gas: gas adds ignition and burner service
- Whether the oven is part of a range or a separate built-in unit
- Control board availability for older models
- Door hinge and gasket parts on European brands
Safety first
- Ovens run on 240 V — shut off the breaker before removing elements, sensors or panels
- For gas ovens, if you smell gas, shut the supply off and ventilate before doing anything else
- Never force a self-clean door lock; the latch mechanism and control board can both be damaged

Common questions
Why did my oven stop heating but the stovetop works?
The cooktop and oven usually use separate circuits. A dead oven with a working cooktop points to the bake element, the oven control board or the oven's thermal fuse — not the main power supply.
How do I know if the oven sensor is bad?
Symptoms include inaccurate temperature, error codes and food that consistently over- or under-cooks. A multimeter resistance check against the model's service values confirms it.
Can I replace an oven element myself?
On most freestanding ranges, yes. The element is held by two screws at the back of the cavity and plugs into a connector. Turn off the breaker and test the old element first.
Why does my oven take so long to preheat?
A weak bake element, a failing sensor or a convection fan that is not running will all stretch preheat times. On gas models, a partially clogged burner or weak igniter is the usual cause.
