There are a variety of reasons a refrigerator isn’t cooling. If you want to spare yourself a little time and burden, give Gaithersburg Appliance Repair a call for refrigerator repair in Gaithersburg, MD. We are happy to come out and troubleshoot the cooling issue as well as fix it for you.

When a refrigerator is no longer cold anymore, it’s time to figure out what the issue might be. Most times it’s something as basic as a routine coil cleaning behind the refrigerator. But, with these new fridges, they are manufactured with a variety of sensors too.

Before we look too deep, we inspect the most common and easy causes for this problem. Here are some things that we have found lead to a refrigerator not cooling:

Is the refrigerator plugged into an outlet? This will seem like it is a odd question, but we have been called out to appointments that this was the problem. For some reason, it was unplugged. Maybe a child or pet unplugged it, or an electrician doing a service visit. Whatever the cause might be, be sure the refrigerator is plugged in.

Check the thermostat inside. This is a very typical issue for families with children in their house. After all, children are fascinated with buttons and dials and so, without understanding they’re doing anything wrong, they mess with them. So, be sure that the thermostat setting isn’t the reason for the warm refrigerator.

Refrigerator Components to Troubleshoot?

Be sure all of the vents inside the freezer area are not blocked with boxes or food. This is common since sometimes frozen vegetables get stuck in the back of the freezer. There can be food in the very back of a freezer that has long been forgotten.

Check that the condenser cooling fan is clear and clean of debris. To do this, unplug the refrigerator and slide it away from the wall. The cooling fan for many models is just at the bottom or somewhere in the back part of the freezer portion. Many times, people don’t think to clean this section of the fridge. But, it is very important to keep it clean. And, it fills up with dust and fuzz quickly, especially in homes that have pets. So, find a rag and get the dust out of the refrigerator coils and fan.

This is not a suggestion for refrigerators that have the rear coil system. Once all clean, plug it back into the wall and notice if the fan spins.

The Freezer is Cold but the Fridge is Not

There are a few more causes for a refrigerator not cooling after these more common ones to start to take a look at if the freezer is cold but your fridge isn’t. The evaporator coils have frost on them. This occurs because there is a malfunction in the defrost heating system. Or if the automatic defrost experiences a problem. The evaporator fan motor is another cause.

Every refrigerator has a set of evaporator coils. These evaporator coils are what gets cold and then the fan moves the cold air around inside the appliance. The damper control assembly working correctly. The temperature control board which provides the electricity to the compressor and fan, this probably isn’t the issue but it’s worth troubleshooting.

And, the thermistor could be defective, which is a little sensor in the appliance that displays the temperature. Having one of our repairmen look at it is the best option but these are a few of of the most common problems.
