This is the ultimate guide for how to fix an electric oven that won’t heat. In this guide, we will discuss why this is most likely happening and how you can fix it.
The main reasons this can happen are a faulty bake element, faulty wiring, faulty power supply, defective thermal fuse, a defective thermostat, or in rare cases a defective control board that needs to be replaced.
Simply start with the first reason on our list and work your way down. Hopefully, you’ll have your oven working again in no time. Please note that to carry out the majority of checks in this guide you will have to have a multi-meter device handy. If you don’t, you’ll need to call a technician to come and inspect your oven.
The main component in your electric oven responsible for heating it is the bake element. When the electrical components within the element short out or the element becomes physically broken it can stop working and your oven won’t heat.
Here’s how to inspect the bake element, and if necessary, replace it:
The next possible cause of your electric oven not heating to check out is faulty wiring. This can be checked by checking the writing that connects the heating element to the control board and the power supply.
Here’s how to inspect the wiring, and if necessary, replace it:
Most electric ovens require two legs of 120 volts (240 total) of current (AC) to be able to heat. If your power supply becomes faulty, your oven might not be able to heat.
Here’s how to inspect the power supply:
If your oven has a thermal fuse (check your user manual) it might have blown which will stop your oven from working. The purpose of the thermal fuse is to monitor the temperature in your oven and turn it off if it overheats.
Here’s how to inspect, and if necessary, replace the thermal fuse:
Some electric ovens have a thermostat with a sensor attached that monitors the oven temperature. When the thermostat believes the oven is at the right temperature, it tells the control board to reduce the voltage being sent to the element. If the thermostat becomes faulty, your oven might not heat.
Here’s how to inspect, and if necessary, replace the thermostat:
If you still haven’t found the cause of your electric oven not heating, your final option is to replace the main control board in your oven. However, given the risk of this not solving the problem, you might be better off getting a 2nd opinion from a technician or purchasing a new oven.
