When your refrigerator is no longer cold, it’s time to see what the issue could be. A lot of times it is something as simple as a routine coil cleaning behind the refrigerator. However, with these modern fridges, they are manufactured with various sensors too.

Before we investigate further, we look at the most typical and common reasons for this problem. Here are a few of issues that we’ve determined lead to a refrigerator that won’t cool:

Is the cord plugged into an electrical outlet? This will seem like it’s a odd question, but we have been hired for appointments that this was the reason for the issue. Somehow, it was unplugged. Maybe a child or pet unplugged it, or an electrician during a service visit. Whatever the case might be, make sure it is plugged in.

Look at the thermostat inside. This is a very typical problem for anyone with small children in the house. After all, children like buttons and dials and so, without knowing they’re doing something bad, they play with them. So, check that the thermostat temperature isn’t the cause of the warm fridge.

Which Refrigerator Components to Inspect?

Be sure all of the vents inside of the freezer area aren’t blocked with boxes or food. This is common because sometimes bags of frozen veggies get stuck in the back. There could be food in the back of a freezer that has long been forgotten about.

Be sure the condenser cooling fan is clear and clean of all debris. To be sure, unplug the fridge 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 part of the freezer section. Often times, people don’t think about cleaning this section of the appliance. But, it is very important to clean it. And, it piles up with fuzz and dust quickly, especially in houses that have dogs and cats. So, get a clean rag and get the built-up dust out of the coils and fan.

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

The Freezer is Cold but the Refrigerator Isn’t

There are many reasons for a refrigerator that won’t cool after these more common ones to start to take a look at if your freezer is cool but the fridge is not. The evaporator coils have frost on them. This occurs when there is a malfunction in the defrost heating system. Or the automatic defrost has an issue. The evaporator fan motor is another cause.

Every fridge has a set of evaporator coils. These evaporator coils are what gets cold and then the fan pushes the cold air around inside the unit. The damper control assembly isn’t working correctly. The temperature control board carries the electricity to the compressor and fan, this probably is not the issue but it is worth troubleshooting.

And, the thermistor could be defective, which is a little sensor within the unit that displays the temperature. Having one of our repairmen look at it is the best course of action but these are some of the most typical issues.
