When your refrigerator is not cold anymore, it’s time to see what the problem could be. Most times it is something as common as a routine coil cleaning behind the appliance. But, with these modern models of refrigerators, they are equipped with a variety of sensors too.

Before we look too deep, we inspect the most typical and common causes for this problem. Here are a few of of the things that we’ve found can lead to a refrigerator that will not cool:

Is it plugged into an outlet? This may seem like a odd question, but we’ve been hired for jobs that this was the reason for the problem. For some reason, the refrigerator was not plugged in. it’s possible a kid unplugged it, or an electrician during a project. Whatever the reason might be, make sure it is plugged in.

Check the thermostat inside of the appliance. This is a very typical problem for anyone with children in their house. After all, kids love dials and buttons and so, without understanding they’re doing something wrong, they play with them. So, check that the thermostat setting isn’t the cause of the warm refrigerator.

Refrigerator Parts to Inspect?

Check that the vents in the freezer area aren’t blocked with containers or food. This is very common since bags of frozen veggies get stuck in the back. There can be food in the way back of a freezer unit that has long been forgotten.

Be sure the condenser cooling fan is clear and clean of all debris. To be sure, unplug the refrigerator and slide it away from the kitchen wall. The fan for most models is right at the bottom of the appliance or somewhere in the back of the freezer unit. A lot of times, customers don’t think to clean this section of the appliance. But, it is important to keep it clean. And, it piles up with fuzz and dust quickly, especially in houses that have pets. So, get a rag and clean the dust out of the refrigerator coils and fan.

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

The Freezer is Cold but the Refrigerator Isn’t

There are a few more reasons for a refrigerator that won’t cool after these obvious ones to start to take a look at if the freezer is cold but the refrigerator is not. The evaporator coils are frosted over. This happens because there is a malfunction in the defrost system. Or if the automatic defrost has an issue. The evaporator fan motor is another reason.

Every fridge has a pair of evaporator coils. These evaporator coils are what cool and then the fan moves the cool air around inside the unit. The damper control assembly is not working the right way. The temperature control board provides the electricity to the fan and compressor, this is not likely the problem but it’s worth mentioning.

And, the thermistor might be defective, which is a small sensor within the appliance that displays the temperature. Having one of our technicians look at it is the best option but these are a few of of the most common issues.
