A freezer’s thermostat is used to regulate the temperature inside the appliance. It works with a probe that measures the current temperature in the freezer. If the temperature rises above a fixed limit temperature, the sensor triggers the cold unit to bring the temperature back down.
If you observe frost constantly in your freezer, without the freezing mode being activated, your thermostat may be damaged.
The thermostat is located in the control box, usually located either on the front or the back of the unit.
The thermostat is a critical component of your freezer. It’s the tool that regulates temperature and keeps your food properly frozen. However, like any component, it can fail over time. Here’s a guide on how to replace your freezer’s thermostat if it ever malfunctions.
Disclaimer: Remember, working with appliances can be dangerous, particularly when you’re dealing with electrical parts. If you’re not confident about doing this safely, it’s best to call a professional.
Tools You’ll Need:
- Screwdriver
- Replacement thermostat

Steps to Replace a Freezer Thermostat
Step 1: Unplug the Freezer
Before you begin any appliance repair, it’s crucial to unplug the unit from the power source. This prevents any accidental electrical shocks during the repair process.
Step 2: Locate the Thermostat
The thermostat is typically found inside the freezer, usually in the upper part. It might be concealed behind a cover panel, which you will need to remove.
Step 3: Remove the Cover Panel
Using a screwdriver, remove the screws holding the panel in place and carefully lift it off to expose the thermostat.
Step 4: Disconnect the Old Thermostat
First, take a picture or make a note of how the wires are connected to the thermostat. This will make it easier to connect the new thermostat correctly. Next, disconnect the wires from the thermostat. Depending on your model, you might need to cut the wires or unfasten any screws holding them in place.
Step 5: Remove the Old Thermostat
After disconnecting the wires, remove the thermostat from its mounting. It might be held in place by screws, clips, or it might just be a pressure fit.
Step 6: Connect the New Thermostat
First, attach the new thermostat to the mounting in the same way the old one was attached. Next, connect the wires to the new thermostat as per the note or picture you took earlier. Secure the connections with wire connectors or electrical tape.
Step 7: Reinstall the Cover Panel
Once the new thermostat is installed and all connections are secure, replace the cover panel and tighten it with the screws you removed earlier.
Step 8: Plug in the Freezer
Finally, plug the freezer back into the power source. Set your desired temperature on the thermostat and monitor the freezer for a few hours to make sure it’s working correctly.
By following these steps, you should be able to replace your freezer’s thermostat successfully. If at any point you feel uncertain or the task becomes too complex, don’t hesitate to call a professional for help. It’s always better to prioritize safety over trying to handle things yourself.
