How to Replace Oven Thermostats

Replacing a Cooker or Oven Thermostat

If you’re experiencing temperature issues with your oven, it might be time to replace the thermostat. The thermostat is a crucial component that regulates the temperature inside the oven.

Here’s a step-by-step guide on how to remove and replace an oven thermostat.

Before we begin…

  1. Disconnect the appliance from any power supply and isolate the supply so it cannot be accidentally reconnected while you are working on it.
  2. Wear gloves! While appliances are nice and smooth on the exterior and pose no risk to cuts etc, the inside of appliances can be extremely sharp as they are not designed for consumers hands to be inside the machine.
  3. If you are not confident in attempting any repair to a domestic appliance, then call an expert.

Materials needed:


  1. Locate the Thermostat – The thermostat is usually located at the back of the oven, inside the control panel. You may need to remove the oven door to gain access to the control panel.
  2. Remove the Old Thermostat – To remove the old thermostat, start by removing the screws that hold it in place. Carefully pull the thermostat out of the control panel and locate the wires that are connected to it.
  3. Label the Wires – Before you disconnect the wires, label them with a piece of tape or a marker. This will help you remember which wire goes where when you’re installing the new thermostat.
  4. Disconnect the Wires – Using needle-nose pliers, gently pull the wires off the terminals of the old thermostat. If the wires are connected using wire nuts, unscrew the nuts and pull the wires apart.
  5. Check the Thermostat – Use a multimeter to check the resistance of the old thermostat. If the resistance is not within the range specified in the manufacturer’s instructions, the thermostat is faulty and needs to be replaced.
  6. Install the New Thermostat – Install the new thermostat by connecting the wires to the terminals. Make sure you connect the wires to the correct terminals, using the labels you made earlier.
  7. Secure the Thermostat – Secure the new thermostat in place by screwing it back into the control panel.
  8. Test the Thermostat – Before you reassemble the oven, test the new thermostat to make sure it’s working correctly. Turn the power back on and set the oven to a specific temperature. Use a thermometer to check if the temperature is accurate. If the temperature is not accurate, you may need to adjust the calibration on the thermostat.
  9. Reassemble the Oven – Once you’re satisfied that the new thermostat is working correctly, reassemble the oven. Put the control panel and oven door back in place, and plug the power cord back in or turn the circuit breaker back on.

In conclusion, removing and replacing an oven thermostat is not a difficult process. Ensure that the oven is disconnected from power, remove the old thermostat, install the new one, and reassemble the oven.

Finally, test the new thermostat to ensure it is working correctly. If you encounter any difficulties, contact a qualified technician for assistance.
