When your refrigerator is not cold anymore, it’s time to figure out what the problem could be. A lot of times it is something as common as a routine coil cleaning. But, with these modern models of refrigerators, they’re equipped with various sensors as well.

Before we investigate further, we monitor the most common and easy causes for this issue. Here are some things that we have determined can lead to a refrigerator that will not cool:

Is it plugged into an outlet? This will seem like a odd question, but we have been called out to appointments that this was the issue. For some reason, the refrigerator was not plugged in. it’s possible a kid unplugged it, or an electrician during a project. Whatever the case may be, make sure it’s plugged in.

Check the thermostat inside. This is a common problem for customers with children in the house. After all, kids are fascinated with buttons and dials and so, without knowing they are doing something bad, they mess with them. So, check that the thermostat temperature is not the reason for the warm fridge.

Refrigerator Parts to Troubleshoot?

Check that each of the vents inside the freezer area are not blocked with boxes or food. This is very common because frozen veggies get stuck in the back. There could be food in the very back of a freezer that has long been forgotten about.

Check that the condenser cooling fan is clean and clear of all debris. To do this, unplug the fridge and slide it away from the kitchen wall. The cooling fan for most models is right at the bottom of the appliance or in the back of the freezer section. Many times, customers don’t think to clean this area of the fridge. But, it is very important to keep it clean. And, it fills up with fuzz and dust quickly, especially in homes that have pets. So, grab a rag and get the built-up dust out of the coils and cooling fan.

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

The Freezer is Cold but the Fridge Isn’t

There are a few more causes for a refrigerator not cooling after these obvious ones to check if your freezer is cold but the refrigerator is not. The evaporator coils are frosted over. This occurs if there is a failure in the defrost heating system. Or the automatic defrost has a problem. The evaporator fan motor is another cause.

Every refrigerator has a pair of evaporator coils. These coils are what cool and the fan pushes the cool air throughout the appliance. The damper control assembly isn’t working properly. The temperature control board which carries the electricity to the compressor and fan, this is not likely the problem but it’s worth mentioning.

And, the thermistor could be defective, which is a tiny sensor inside the unit that tells the temperature. Having one of our technicians look at it is the best solution but these are a few of of the most common issues.
