Tools and Materials
Before embarking on this mission, gather the necessary tools:

- Multimeter
- Replacement thermostat (matched to your oven model)
- Electrical tape
- Wire nuts
Safety Precautions
Safety first! Ensure your oven is unplugged and has cooled down before commencing any work.
Identifying the Thermostat
Locate the thermostat, typically situated behind the oven’s control panel. It’s a small, cylindrical device with wires attached.
Testing the Thermostat
Using a multimeter, check the thermostat’s continuity. Disconnect the wires and set the multimeter to the ohms setting. Touch the probes to the thermostat’s terminals. A reading of zero or close to zero indicates a faulty thermostat.
Disconnecting the Thermostat
Once confirmed as faulty, disconnect the thermostat by unscrewing the wire nuts connecting it to the oven’s wiring harness. Note the position of each wire for reassembly later.
Removing the Thermostat
Remove the mounting screws holding the thermostat in place. Gently pull it out, taking care not to damage the wires.
Installing the New Thermostat
Insert the new thermostat into the mounting bracket and secure it with screws. Connect the wires to the thermostat’s terminals, matching the colors or markings. Tighten the wire nuts securely.
Reassembling the Control Panel
Place the control panel back in position and secure it with screws.
Testing the New Thermostat
Plug the oven back in and set the temperature to a known value. Use a thermometer to measure the oven’s temperature. If it matches the setting, your thermostat replacement was successful.
Troubleshooting
If the oven temperature is still incorrect, check the following:
- Ensure the wires are connected correctly.
- Test the new thermostat again using a multimeter.
- Inspect the oven’s heating element for any damage.
Conclusion: Oven Nirvana Restored
