In some cases, the issue may not be with the bake element, but with the broil element or the oven’s wiring. If you are unsure about oven repairs or replacements, it is always best to contact a professional technician.

Temperature Sensor Problems

One of the most common reasons for an oven not heating properly is due to problems with the temperature sensor. The temperature sensor is responsible for monitoring the oven’s temperature and signals the control board to turn the heating element on or off to maintain the desired temperature. If the temperature sensor is not working correctly, your oven may not heat up or may overheat.

To troubleshoot the temperature sensor, you will need a multimeter to test the sensor’s resistance. Unplug the oven and locate the sensor probe, typically located at the back of the oven. Remove the sensor and disconnect the wiring harness. Using the multimeter, test the sensor’s resistance at room temperature; it should read between 1000-1100 ohms. If it reads higher or lower than that, the sensor is faulty and will need to be replaced.

To replace the temperature sensor, first, ensure the oven is unplugged. Locate the sensor probe and remove it from the oven cavity. Disconnect the wiring harness and remove any mounting screws or clips. Install the new sensor probe in the same location and reattach the wiring harness and mounting clips or screws.

If you’re uncomfortable performing these tasks yourself, it’s best to consult a professional technician to diagnose and repair your oven.

Oven Control Board Malfunction

If your oven is not heating up, it could be due to a faulty oven control board. This component controls the oven’s heating elements, and if it malfunctions, your oven will not heat up as it should. Some common signs of a malfunctioning control board include the control panel not responding or showing error messages.

To troubleshoot this issue, first, check the power supply to your oven. If the power supply is functioning correctly, then the issue is likely with the control board. You can try resetting the control board by turning off the power to your oven for a few minutes and then turning it back on. If this doesn’t resolve the issue, you may need to replace the control board.

Replacing the control board can be a complicated process, and if you’re not comfortable doing it yourself, it’s best to consult a professional technician. They can diagnose the issue and replace the control board if necessary.

Common Control Board Error Codes
