Oven Thermostat

RepairClinic Item # 627538

The oven thermostat regulates the oven temperature. If there is an oven temperature problem, this thermostat might be defective. The thermostat is very difficult to test due to its complexity. The oven thermostat has a thin copper tube attached to a slightly thicker tube which sticks into the oven. Inside this tube is a type of hydraulic fluid. As the temperature in the oven rises the fluid expands which puts pressure on a small activator inside the thermostat and shuts off the heat. As the oven cools, the pressure reduces and the activator allows the oven to heat. If there is an oven temperature problem it could be that the thermostat activator is broken, or that the calibration has changed. The solution is to replace the oven thermostat.
