Temperature Sensor
It’s possible that the reason your oven is too hot is a fault in the temperature sensor, which regulates oven temperature in modern ranges, like a thermostat. It’s located on the back wall of the inside of your oven, near the broiler on the top wall. On a newer oven, there may be a fault code displayed. Check your owner’s manual or the manufacturer website to find out the proper resistance of the temperature sensor, unplug the oven, and use a multi-meter to see if your sensor’s at the correct resistance.
Oven Control Thermostat
If your oven is running too hot, your problem could be a thermostat that isn’t working. The thermostat, part of the main control panel, regulates the broil and bake elements via temperature-sensitive contacts that send electricity to those elements. Since the thermostat’s rarely at fault for an oven that’s not getting too hot, check the other components before looking at the thermostat First, unplug the oven. Then use a multi-meter to check the contacts of the thermostat for continuity. If there’s an adjustment screw on the back of the thermostat, that means it can be re-calibrated using an accurate thermometer. Some thermostats allow you to move the calibration as much as 50 degrees F.
