How To Fix An Oven That's Too Hot

On modern electronic control ranges, the oven temperature sensor is the part that monitors the oven temperature and signals the electronic control to turn the elements on and off. If it is not working properly it could be the reason why the oven is producing little or no heat. This part can be found inside the oven and is usually located near the broil element. Most modern ovens will display a fault code if the oven sensor is at fault. If you think the sensor may be the issue you can check the resistance with a multi-meter but will need to know the correct resistance of the sensor at room temperature. Remove power from the appliance before performing this test.

The oven control thermostat is located in the main control panel and controls the bake and broil elements. It is a temperature controlled switch and as such will have contacts that supply power to these elements. A malfunctioning thermostat can cause your oven to produce too little, too much or no heat at all. For a symptom of not enough heat the oven thermostat, although unlikely, may be at fault. You should eliminate all other components first. Some controls can be calibrated up to 50 degrees Fahrenheit but you will require an accurate thermometer to perform this task.

The adjustment screw is normally located on the back of the control, but if sealed, it is not meant to be calibrated. Remove power to the appliance before performing this test. If the bake or broil elements are not receiving power, then you can check the appropriate contacts of the oven thermostat for continuity with a multi-meter.
