When a refrigerator isn’t cold anymore, it is time to see what the issue might be. Often times it’s something as common as a routine coil cleaning behind the refrigerator. However, with modern refrigerators, they are manufactured with various sensors as well.

Before we look too deep, we look at the most common and common causes for this problem. Here are a few of issues that we’ve determined can lead to a refrigerator not cooling:

Is the cord plugged into an outlet? This may seem like it is a silly question, but we’ve been hired for jobs that this was the issue. Somehow, the refrigerator was not plugged in. Maybe a a pet unplugged it, or an electrician while doing a service visit. Whatever the cause might be, be sure the refrigerator is plugged in.

Check the thermostat inside of the unit. This is a common problem for customers with small children in the house. After all, children are fascinated with buttons and dials and so, without understanding they are doing anything wrong, they mess with them. So, be sure that the thermostat setting isn’t the reason for the warm refrigerator.

Refrigerator Parts to Inspect?

Be sure each of the vents inside of the freezer are not blocked with food or containers. This is very common since frozen vegetables get jammed in the back of the freezer. There might be food in the way back of a freezer that has been forgotten about.

Check that the condenser cooling fan is clear and clean of all debris. To be sure, unplug the refrigerator and pull it out from the wall. The cooling fan for many models is right at the bottom or in the back part of the freezer unit. A lot of times, people don’t think about cleaning this area of the fridge. But, it is very important to clean it. And, it piles up with dust and fuzz quickly, especially in houses that have pets. So, get a clean rag and get the built-up dust out of the coils and fan.

This is not suggested for refrigerators that have a rear coil system. Once everything is clean, plug it into the wall and notice if the cooling fan moves.

The Freezer is Cold but the Refrigerator Isn’t

There are many causes for a refrigerator that won’t cool after these more common ones to start to check if the freezer is cool but the refrigerator is not. The evaporator coils have frost on them. This happens if there’s a failure in the defrost heating system. Or the automatic defrost has a problem. The evaporator fan motor can be another cause.

Every fridge has a pair of evaporator coils. These coils are what gets cold and then the fan moves the cool air throughout the appliance. The damper control assembly working correctly. The temperature control board which transports the electricity to the fan and compressor, this probably isn’t the problem but it is worth mentioning.

And, the thermistor could be defective, which is a tiny sensor within the appliance that tells the temperature. Having one of our repairmen inspect it is the best course of action but these are some of the most common problems.
