Refrigerator Not Cooling? Here’s How to Troubleshoot and Fix It


When your refrigerator stops cooling, it’s a major inconvenience. Food spoils quickly, and you need to act fast. In Calgary and the surrounding area, Fast Appliance Repair- Fridge Repair Calgary is here to help. Follow this guide to troubleshoot and fix your refrigerator.

Common Reasons Your Refrigerator Isn’t Cooling

1. Power Issues

First, check if your refrigerator is receiving power. Plug another appliance into the same outlet to test it. If it doesn’t work, check your circuit breaker. Sometimes, a tripped breaker can be the problem. Reset it and see if your refrigerator starts working.

2. Thermostat Settings

Next, check the thermostat settings. Make sure the dial is set to the correct temperature. Sometimes, it can get accidentally adjusted. Set it between 35 and 38 degrees Fahrenheit (1.7 to 3.3 degrees Celsius). Wait a few hours to see if the temperature improves.

3. Blocked Vents

Airflow is crucial for your refrigerator. Check the vents inside the fridge and freezer. Make sure they are not blocked by food items. Blocked vents restrict airflow, causing cooling issues. Rearrange your food to clear the vents.

4. Dirty Condenser Coils

Condenser coils dissipate heat. When they are dirty, they can’t do their job effectively. Pull your refrigerator away from the wall and locate the coils. Use a coil brush or vacuum to clean them. Be gentle to avoid damaging the coils.

5. Faulty Evaporator Fan

The evaporator fan circulates air inside your refrigerator. If it stops working, your fridge won’t cool properly. Listen for a fan noise when you open the fridge door. If you don’t hear it, the fan might be faulty. You may need to replace it.

6. Defective Door Seals

Check the door seals for any gaps or cracks. A tight seal is essential for maintaining the internal temperature. Close the door on a piece of paper. If you can pull it out easily, the seal is worn out. Replace the door seals to improve cooling.

7. Refrigerant Leak

A refrigerant leak is a serious issue. Your refrigerator won’t cool without enough refrigerant. If you suspect a leak, call Fast Appliance Repair. We can handle refrigerant issues safely and efficiently.

Step-by-Step Troubleshooting Guide

Step 1: Check the Power

Ensure your refrigerator is plugged in. Check the outlet with another appliance. If there’s no power, reset your circuit breaker. Still no luck? You might have an electrical issue. Contact an electrician to inspect your wiring.

Step 2: Adjust Thermostat Settings

Locate the thermostat inside your refrigerator. Adjust it to the recommended temperature. Wait a few hours to see if the temperature stabilizes. If it doesn’t, move on to the next step.

Step 3: Clear the Vents

Inspect the vents inside your fridge and freezer. Remove any food items blocking them. Ensure air can flow freely. This simple step can solve many cooling problems.

Step 4: Clean the Condenser Coils

Unplug your refrigerator before cleaning. Pull it away from the wall and find the condenser coils. Use a coil brush or vacuum to remove dust and debris. Clean coils improve efficiency and cooling performance.

Step 5: Inspect the Evaporator Fan

Open your refrigerator door and listen for the fan. If you don’t hear it, the fan might be broken. You’ll need to replace it. Fast Appliance Repair can assist with this repair.

Step 6: Examine the Door Seals

Check the door seals for damage. Use the paper test to check for gaps. Replace any worn-out seals to ensure a tight closure. Proper seals keep cold air inside.

Step 7: Look for Refrigerant Leaks

If your refrigerator still isn’t cooling, you might have a refrigerant leak. This is a complex issue requiring professional help. Fast Appliance Repair can diagnose and fix refrigerant problems.

Preventive Maintenance Tips

Clean the Coils Regularly

Dirty coils reduce efficiency. Clean them every six months to keep your fridge running smoothly. This simple task can prevent many cooling issues.

Check Door Seals

Inspect door seals for wear and tear. Replace them if you notice gaps. This ensures a tight seal, keeping cold air in and warm air out.

Set the Right Temperature

Keep your refrigerator between 35 and 38 degrees Fahrenheit. This prevents spoilage and keeps your food fresh. Avoid setting it too cold, as this can freeze your food.

Don’t Overload the Fridge

Overloading restricts airflow. Leave space around the vents to ensure proper circulation. This helps maintain an even temperature.

Regularly Defrost Your Freezer

If your freezer doesn’t have auto-defrost, do it manually. Ice buildup can affect cooling. Defrosting prevents this issue and improves efficiency.
