All Posts

When your refrigerator stops cooling, it can quickly turn into a household emergency. Spoiled food, melted ice, and a frustratingly warm fridge can disrupt your daily life and cost you money. Before you panic and start pricing new appliances, take a moment to troubleshoot. Many refrigerator cooling problems can be resolved with a bit of know-how and a few tools.

In this comprehensive guide, we’ll break down the most common causes behind a refrigerator not cooling and show you step-by-step how to diagnose and fix them.

1. Check the Power Supply

It may seem obvious, but your refrigerator needs consistent power to operate. Start by making sure it’s plugged in securely. Inspect the power cord for damage and verify that the outlet is functioning.

Quick Tip: Unplug the fridge and plug in another appliance to confirm the outlet is live.

2. Inspect the Thermostat Settings

Accidentally bumped the temperature dial? Double-check the thermostat inside the fridge and ensure it's set between 35°F and 38°F. If your unit has digital controls, reset them to factory settings and monitor changes.

3. Clean the Condenser Coils

Dusty or dirty condenser coils can prevent your fridge from cooling properly. These coils are typically located at the back or bottom of the unit and help release heat from inside.

How to Clean Coils:

  • Unplug the fridge.

  • Use a coil brush or vacuum to remove dirt and dust.

  • Clean coils every 6 months to maintain efficiency.

4. Examine the Evaporator Fan

The evaporator fan circulates cold air throughout the fridge. If it’s not working, your freezer might stay cold while the refrigerator warms up.

Troubleshooting:

  • Open the freezer door and listen for the fan.

  • If silent, remove the back panel in the freezer and test the fan motor with a multimeter.

  • Replace the fan if it’s faulty.

5. Assess the Condenser Fan Motor

Some refrigerators have a condenser fan motor near the compressor. If it fails, the fridge may overheat and stop cooling.

Steps:

  • Locate the fan near the compressor.

  • Clear away debris.

  • Use a multimeter to test continuity.

6. Look for Frost Buildup on the Evaporator Coils

If your fridge has frost buildup, the defrost system might be to blame. This can prevent air from circulating properly.

Defrost System Includes:

  • Defrost timer

  • Defrost heater

  • Defrost thermostat

Tip: Manually defrost the fridge by unplugging it for 24 hours and observe whether the cooling returns.

7. Check the Start Relay

The start relay helps the compressor turn on. A faulty relay can lead to a non-functional compressor.

How to Test:

  • Unplug the fridge.

  • Locate the relay on the compressor.

  • Test for continuity with a multimeter.

8. Inspect the Compressor

If none of the above issues are present, the compressor may be defective. This component compresses refrigerant and is essential for cooling.

Signs of a Bad Compressor:

  • Clicking noise followed by silence

  • No humming or vibration

Note: Replacing a compressor is a job best left to professionals. You can always call a Puls technician, who is trained to handle all types of refrigerators and brands with efficiency and care.

9. Door Seal Problems

A broken or loose door gasket allows cool air to escape, making your fridge work harder.

DIY Fix:

  • Clean the seal with warm soapy water.

  • Replace if cracked or doesn’t form a tight seal.

10. Internal Airflow Issues

Improperly loaded fridges can block vents and restrict airflow.

Solution:

  • Keep food away from vents.

  • Avoid overstuffing your fridge.


When to Call a Professional

If you’ve tried all the steps above and your refrigerator still isn’t cooling, it may be time to bring in an expert. Especially for issues related to the sealed system or refrigerant leaks, professional repair is necessary.

Look for these signs:

  • Burnt smells

  • Electrical sparks

  • Compressor not starting

  • Persistent frost buildup

Don’t wait for a small issue to become a big headache. Puls technicians are experienced with all appliance brands and can quickly identify and fix the root of the problem. Schedule a service today and get your fridge cooling again in no time.


Preventative Tips to Keep Your Fridge Cooling

  • Clean condenser coils regularly.

  • Keep fridge at least ¾ full for consistent cooling.

  • Avoid frequent door opening.

  • Replace door seals every few years.
