When your refrigerator stops cooling, it doesn’t just disrupt your kitchen it threatens your food supply, your budget, and your daily routine. Whether you hear the fan running but feel no chill or everything seems dead silent, this guide will walk you through how to troubleshoot a refrigerator that’s not cooling before calling in the professionals.
In this article, we will discuss the most frequent causes as well as DIY things you can do before calling for refrigerator repair assistance.
Common Causes Why Your Refrigerator Won’t Cool
Understanding the core reasons behind cooling issues can save you time and stress. Below are some of the most frequent causes:
1. Filthy Condenser Coils
Dust and debris buildup on condenser coils force your refrigerator to work harder and can reduce cooling efficiency or stop it entirely.
Solution: Unplug your unit, find coils (typically on back or bottom), and clean with a coil brush or vacuum.

2. Thermostat Issues
If it is set too high or if it is malfunctioning, then your refrigerators will not cool properly.
Solution: Check that your thermostat is between 37°F and 40°F. In case changing the temperature does nothing, a malfunctioning thermostat may require replacement.
3. Faulty Evaporator Fan
The evaporator fan blows cold air from the coils into the rest of the fridge. Without it, your fridge won’t cool evenly or at all.
Solution: Check the freezer and listen for the fan while running. The absence of noise may mean you need a replacement.
4. Malfunctioning Start Relay
Start relay assists with powering the compressor. In case it is damaged, then your compressor will not start, meaning no cooling.
Solution: A technician will use a multimeter to test this component. Replacing a defective start relay is a typical refrigerator repair solution.
5. Frosted Evaporator Coils
Excessive frost on evaporator coils impedes air movement, decreasing cooling.
Solution: Defrost your refrigerator manually by unplugging it for 24 hours. In case the issue comes back soon, you can have a defrost system failure, and you will need professional help.
6. Blocked Vents
Lacking sufficient air circulation due to obstructed vents can cause temperature variations.
Solution: Make sure food products aren’t stored too near the air vents of both the fridge and freezer sections.
DIY Refrigerator Troubleshooting Checklist
Before scheduling a service call, try the following steps:
- Verify power connections and make sure the unit is connected
