Oven not heating on an electric range usually means a burnt-out bake element, but check the simple things first: the settings, the lock mode and the breaker. A failed temperature sensor, thermal fuse or control board can also stop heat. Always switch the oven off at the breaker before inspecting or touching any element or wiring.
Oven not heating: the quick answer
An electric oven heats through the bake element in the bottom and the broil element at the top. If one element works and the other does not, that element has failed. If neither heats and the display works, look at the sensor, thermal fuse, relay or control board. If the display is dead too, check the breaker and wiring.
| Quick facts: oven not heating | |
|---|---|
| Time needed | 15 minutes for checks; 30 to 60 minutes to swap an element |
| Tools | Screwdriver, multimeter, replacement element |
| Difficulty | Easy to moderate for an element; technician for board faults |
| Safety | Switch off the breaker and let the oven cool before touching parts |
Easy checks
- Check the mode. Make sure the oven is set to bake or convect, with a temperature chosen. Broil-only or timed bake can confuse settings.
- Check for locks or demo mode. A control lock, Sabbath mode or delay start may stop heating.
- Check the breaker. Electric ovens use a double breaker. If one side has tripped, the display may work but the elements will not heat.
- Look at the bake element inside the oven. A visible break, blister or burnt spot means it has failed.
- Check a gas oven's igniter if you have a gas range. See our guide for a gas oven that will not light.
Likely failed parts
| Part | Sign | Fix |
|---|---|---|
| Bake element | Not glowing red, visible damage | Replace the element |
| Broil element | Top does not glow | Replace the element |
| Temperature sensor | Oven heats unevenly or not at all, error code | Test resistance, replace |
| Thermal fuse | No heat at all, display works | Replace after finding the cause |
| Relay or control board | Display works, no heat or erratic heat | Technician |
| Door lock motor (self-clean) | Door locked, oven won't run | Technician |
Replacing a bake element
- Switch off the breaker and let the oven cool.
- Remove the screws holding the element to the back wall.
- Pull the element forward gently, unplug the wires or connectors, and note their positions.
- Connect the new element, secure it, and restore power.
Order the exact element for your model number. Do not touch the wires with power on.
The temperature sensor
The sensor is a thin probe at the back of the oven. At room temperature its resistance is typically around 1,000 ohms, but the exact value depends on the model. A reading far off, or an open circuit, means replacement. A faulty sensor can make an oven not heating, or heating inaccurately.
When the problem is the board
Control boards and relays are the most expensive parts. Burn marks, dead sections of the display, or clicking without heat suggest a relay or board fault. An oven not heating on an older range may be cheaper to replace than to repair, so ask for a quote. Many ovens show an error code when the sensor or board has a fault; write the code down, switch the oven off at the breaker for a minute to reset it, and give the code to the technician, because it often points straight to the failed part.
When to call a professional
Call if the element is fine, if the display is erratic, if you see burnt wiring, or if you smell burning. Gas oven repairs should go to a licensed technician.
Oven not heating: safe checks before a repair
Before calling a technician, check that the oven has power and that the control is set correctly. An oven not heating can result from a tripped breaker, a faulty door switch or a failed element. Look for visible damage on the bake or broil element, and check whether the oven is in self-clean mode, which can lock the controls. Let the oven cool completely before you touch any part. If the oven does not heat after these checks, the sensor, the control board or the wiring may be at fault.

Frequently asked questions
Why is my oven not heating?
On an electric oven, a burnt-out bake element is the most common cause. Others are a tripped breaker, lock mode, a failed temperature sensor, a thermal fuse, or a relay or control board fault.
How can I tell if my oven bake element is bad?
With the oven on bake, the element should glow orange-red. A visible break, blister or burnt spot, or no glow at all, means it has failed. A multimeter test with the power off confirms it.
Why does my electric oven have power but no heat?
The display and lights work on a low-voltage supply. If a leg of the double breaker has tripped, or the element, sensor or thermal fuse has failed, the display works but the oven does not heat. Check the breaker first.
Is it safe to replace an oven element myself?
Usually yes, if you switch off the breaker, let the oven cool, and match the part. If wiring is burnt or you are uncomfortable with electrical work, a technician is the safer choice.
What does the oven temperature sensor do?
It tells the control how hot the oven is, so it can cycle the element on and off. A faulty sensor can cause no heat, poor heating or incorrect temperature. It can be tested with a multimeter and replaced.
Why is my self-cleaning oven not heating after a cleaning cycle?
The high temperature of the cycle can blow a thermal fuse, damage the sensor or burn out an element. The door lock may also have jammed. A technician can check these parts after a cleaning cycle.
Is it worth fixing an oven not heating?
An element, sensor or fuse is usually worth fixing. A failed control board on an old range may cost close to a replacement. Get a quote and compare it with the age and value of the oven.
When should I call a technician for an oven not heating?
Call if the element tests fine, the display is erratic, you smell burning or see burnt wiring, or you are unsure with electrical work. Always call a licensed technician for gas ovens.
Can a tripped breaker stop an electric oven heating?
Yes. Electric ovens use a double breaker, and a tripped breaker can leave the lights on with no heat. Reset it fully and test again. If it trips repeatedly, call a professional.
How long does an oven element last?
Often several years, but heat and wear eventually cause failure. If the element looks blistered or broken, or does not glow red, it needs replacing. Many ovens give years of service, and replacement is straightforward when you match the part to the model.
