It’s always frustrating when you discover that your refrigerator won’t cool. A broken refrigerator can cause hundreds of dollars in wasted food. Obviously, this is a problem that you’ll need to get fixed as soon as possible.

By trying to diagnose the problem yourself, you can save time and money when it comes to hiring a repair technician. Use this guide to troubleshoot why your refrigerator won’t cool properly.

Most Common Reasons
Your Refrigerator Won’t Cool

Temperature Set Incorrectly

The first thing you should always check in the case of a refrigerator not cooling is the temperature gauge. Many times, the temperature gauge will get bumped to the wrong setting. This is an extremely easy fix and happens more often than you might think.

Dirty Condenser Coils

The condenser coils are an essential part of keeping refrigerators cool. Unfortunately, these coils will get covered in dust and debris over time which causes them to work much harder to cool the fridge down.

If the condenser coils on your refrigerator are dirty, it could be the cause of your refrigerator cooling problems. This is one of the most common reasons for a fridge that won’t cool, and luckily, it’s a pretty easy fix for any repair technician.

Broken Evaporator Fan Motor

The evaporator fan motor is responsible for pulling cooled air into the cabinet of your refrigerator and freezer. If this part breaks, the cooled air from the evaporator coils cannot be drawn into the fridge. Since this is one of the key components of cooling your fridge, even a slight malfunction can cause your fridge to stop cooling properly.

If you think this is what’s wrong with your refrigerator, call a repair technician today to get the part changed out and get your refrigerator back to the right temperature.

Malfunctioning Thermistor

Thermistors are a sensor that takes the temperature of your fridge and freezer cabinets and sends it to the main control board. This ensures that your refrigerator is maintaining the temperature that it’s set to on the temperature controller at all times.

In the case of a malfunctioning thermistor, it could send incorrect signals to the main control board, telling the computer that the refrigerator is at the proper temperature when, in fact, it is much higher than it should be. When this happens the main control board will not turn on the evaporator fan to pump in more cold air, resulting in a refrigerator no cool situation.

In most cases, a refrigerator won’t cool due to a physical part rather than a digital malfunction or sensor defect, but as modern appliances become more advanced, this kind of sensor defect is a more common issue.

Defective Compressor

The compressor is one of the most important parts of any refrigerator. It’s responsible for compressing refrigerant and pumping it through the system that cools your fridge. Usually, the compressor is not the issue when your refrigerator is failing to cool, but if you’ve gone through the list of other commonly defective parts, it could be the culprit. This part will require a specialist to test and replace.
