How to Replace a Faulty Refrigerator Thermostat at Home

A faulty thermostat is one of the most common causes behind cooling issues in refrigerators. If your fridge feels warmer than it should or runs constantly without shutting off, the thermostat could be to blame. At Beach 2 Bay Appliance Services, LLC, we want to help you understand how to handle basic refrigerator repair tasks at home—starting with thermostat replacement.

Signs Your Refrigerator Thermostat May Be Failing

Before replacing anything, it’s important to confirm the issue. Here are a few signs that your thermostat might be the problem:

• Fridge isn’t cooling properly

• Fridge is too cold or freezing food

• The compressor runs constantly or not at all

• The temperature dial has no effect

If you notice any of these, it’s time to test and possibly replace the thermostat.

Tools You’ll Need

You don’t need a professional toolkit for this. Just gather these basic items:

• Screwdriver set

• Needle-nose pliers

• Multimeter (for testing continuity)

• Replacement thermostat (check your refrigerator’s model number)

Step-by-Step Guide to Replacing a Refrigerator Thermostat

Step 1: Unplug the Refrigerator
Always start by cutting the power. Unplug the fridge to avoid any electrical hazards while working.

Step 2: Locate the Thermostat
In most models, the thermostat is inside the fridge, near the temperature control dial. You may need to remove a cover or panel.

Step 3: Remove the Faulty Thermostat
Unscrew the thermostat from its mount. Carefully disconnect the wires, taking note of where each one connects.

Step 4: Test the Thermostat (Optional)
Use a multimeter to check for continuity. If there’s none, the thermostat is bad and needs replacement.

Step 5: Install the New Thermostat
Attach the wires to the new thermostat just as they were connected before. Mount it securely in place and reattach any covers or panels.

Step 6: Plug the Fridge Back In
Power the fridge on and wait a few hours to see if the cooling improves.
