If your electric oven is no longer heating, there may be a problem with the bake or broil element, temperature control thermostat, temperature sensor, or control board.
Troubleshooting an electric oven that does not heat can seem complex, but there are some easy things to check first that do not require a lot of expertise, or time spent disassembling or testing parts. We will take you from the easiest and most-common elements and parts to check, to the more complex parts in order to fix your range that does not heat.
Although your electric stove might be a Frigidaire, LG, Samsung, Maytag or Amana, many of these appliances will contain the same types of parts that work in the same way – no matter what the brand. However, you should always go by the model number located on your appliance when looking to replace a part.
When looking to how to fix an oven that no longer heats, here are a few parts you should check out.
Bake or Broil Element
The bake or broil element provides the heat inside your oven. Sometimes you can observe the element turning red when turned on. If your oven is no longer heating, this is an easy part to check for signs of defects. Look for signs of blistering or breakage on the part itself. However, sometimes the part will show no signs of damage, but still be defective. In that case, test the part for continuity. If the element tests negative for continuity, it will need to be replaced.
If your oven is not heating up at all, it might be due to a blown thermal fuse. The thermal fuse is a safety device and shuts off the oven when it is overheating or receiving too much voltage. If the thermal fuse is blown, it will need to be replaced.
The thermostat and sensor monitors the oven temperature and shuts off power to the bake or broil elements once the correct temperature is reached. This cycle is then repeated in order to maintain the proper temperature.
Models that have an electronic control board instead of a thermostat, will use a sensor to monitor the inside oven temperature. If the sensor is faulty, then voltage to the part will be shut off too early, or not at all. A fault code may appear on the display if the temperature sensor is not functioning properly.
The oven control board provides power to the bake and broil elements. If the control board is faulty, it will not send voltage to the heating elements. Since the control board is not easy to test, be sure to check for other causes for your oven not heating, including the above parts, blown fuses, and that the wall outlet works and the proper voltage is flowing from the outlet.
Check for any oven error codes showing that the control board faulty. Remove and inspect the control board for any physical signs of burning along the wiring or part and replace.
