When a refrigerator is no longer cold, it’s time to see what the issue is. Most times it is something as simple as a good coil cleaning. However, with these latest models of refrigerators, they’re manufactured with a variety of sensors too.

Before we investigate further, we look at the most common and simple reasons for this problem. Here are a couple of of the things that we’ve found lead to a refrigerator that won’t cool:

Is the cord plugged in? This might seem like it is a odd question, but we’ve been called out to jobs that this was the reason for the issue. Somehow, the refrigerator was not plugged in. it’s possible a a pet did it, or an electrician during a project. Whatever the case may be, make 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 like dials and buttons and so, without understanding they are doing anything bad, they mess with them. So, be sure that the thermostat setting is not the cause of the warm fridge.

Which Refrigerator Parts to Inspect?

Check that the vents inside the freezer area are not blocked with containers or food. This is very common since bags of frozen veggies get pushed in the back. There might be food in the back of a freezer that has long been forgotten.

Check that the refrigerator’s condenser cooling fan is clean and clear of all debris. To be sure, unplug the refrigerator and slide it out from the wall. The cooling fan for many models is right at the bottom or somewhere in the back of the freezer portion. A lot of times, customers do not think to clean this section of the fridge. But, it’s important to keep it clean. And, it piles up with fuzz and dust quickly, especially with homes that have dogs and cats. So, find a clean rag and clean the built-up dust out of the refrigerator coils and cooling fan.

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

The Freezer is Cold but the Fridge is Not

There are many reasons for a refrigerator not cooling after these more common ones to check if the freezer is cold but the refrigerator is not. The evaporator coils have frost on them. This happens because there’s a malfunction in the defrost heating system. Or the automatic defrost experiences a problem. The evaporator fan motor is another reason.

Every refrigerator has a pair of evaporator coils. These coils are what gets cold and then the fan moves the cool air around inside the unit. The damper control assembly is not working correctly. The temperature control board provides 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 appliance that tells the temperature. Having one of our repairmen look at it is the best option but these are some of the most common problems.
