How to Replace Range/Stove/Oven Temperature Control Thermostat

  1. Disconnect power supply:
    Locate the circuit breaker for the oven and switch it off before starting work to prevent electric shock.

  2. Remove control knobs:
    Gently pull the control knobs straight off the stems on the stovetop to access the thermostat.

  3. Take off the backguard:
    Unscrew any screws or brackets on the backguard and remove it to access the rear of the thermostat.

  4. Disconnect wiring:
    Identify each thermostat wire connection and remove them. Tape the wires to keep them organized for reassembly.

  5. Unmount the old thermostat:
    Remove the mounting screws to detach the old thermostat from the oven. Be careful not to lose any parts.

  6. Install the new thermostat:
    Secure the new thermostat in place with the mounting screws. Reconnect the wires, matching them to their original connections.

  7. Replace the backguard:
    Carefully reattach the backguard with the screws and brackets, ensuring all wires are secure.

  8. Reattach the knobs:
    Line up the knobs and gently push them back onto the control stems until fully seated.

  9. Restore power:
    Return to the circuit breaker and switch the oven power back on.

  10. Test operation:
    Set the oven to various temperatures and verify accurate readings. Calibrate if needed according to the manufacturer’s instructions.

By following these steps, you can effectively replace the temperature control thermostat in your range or oven, ensuring accurate temperature settings and reliable operation.

Most Common Solution

The oven thermostat is responsible for regulating the temperature of the broiler. If there is a malfunction with the broiler, it could be due to a faulty thermostat. This component consists of a thin copper tube connected to a slightly thicker one that extends into the oven. Inside the tube, there is a specialized hydraulic fluid. As the broiler heats up, the fluid expands, exerting pressure on a small mechanism within the thermostat to shut off the heat. Once the broiler cools down, the pressure decreases, allowing the heat to resume. Testing the oven thermostat can be challenging, and if it is indeed broken, it will need to be replaced to resolve any issues with the broiler's operation.
