If you discover that your refrigerator is not getting cool enough or not cooling down at all, then it is perfectly possible you may need to change your refrigerator thermostat. If you wish to test the thermostat to make sure whether it is working or not, then you should change the refrigerator temperature to something a bit cooler than normal. If the thermostat is working okay then it will take a few hours to maintain a steady temperature. However, if it doesn’t then it will need replacing.

Step 1 – Preparation for Replacing Thermostat

The first thing you should do before undertaking this work is to turn off the appliance from the mains. This is something that should be done with all appliances of an electrical nature for safety reasons. If you find that the plug is hidden away behind cupboards or panels then you should turn off all the power to the entire kitchen.

Step 2 – Locate the Thermostat

Next you need to find the thermostat and where it is positioned inside the refrigerator. For the majority of refrigerators where they have a freezer on the top level, the thermostat will be right at the back of the fridge or on the roof of the fridge on underneath the freezer panel. If you have a refrigerator that is next to the freezer then the thermostat should be found in the freezer at the back.

Step 3 – Remove Shelving

Ensure that you take out all frozen food and shelves that are in your way that many prevent you from working on the job with plenty of space to move about in. In order to take out some of the shelves on the inside you may have to make a few screws loose and take out clips holding it in place.

Step 4 – Remove Wires

There will be some wires that are attached to the thermostat and these need to be pulled away gently using the pliers. You should make sure that you are extremely careful doing this as if you pull too hard or grip the wires in the middle then they could break under the pressure.

Step 5 – Take the Broken Thermostat Out

You are now in a position to take the old faulty thermostat out of the refrigerator after taking out the remaining screws and clips. If the thermostat is around an evaporator tube then you should take care then removing as this may cause damage.

Step 6 – Install the New Thermostat

Once you have gone through all the steps, then you should put the new replacement thermostat in to the refrigerator in the same place as the old one. Ensure that you screw it into place and reconnect all the wires. Ensure that when you have done this and put the panel back on to the thermostat that it is secure. Next put back any shelving you took out before replacing the thermostat.

Step 7 – Test the Refrigerator

Finally, turn the power to the refrigerator back on and then wait for the refrigerator to cool down again to a lower temperature. If the new thermostat is working correctly then it will kick in and maintain a steady temperature within your refrigerator.
