Why Your LG Refrigerator Is Not Cooling (And How to Fix It)

An LG refrigerator that stops cooling can cause frustration and food waste. Several common issues can lead to this problem. This guide explains possible causes and how to fix them. If you need expert help, contact appliance repair San Diego for fast service.

# 1. Dirty Condenser Coils

Condenser coils release heat from the refrigerator. When they collect dust and debris, cooling efficiency decreases.

Fix:

• Unplug the refrigerator.

• Use a vacuum or brush to clean the coils.

• Perform this maintenance every six months to ensure optimal performance.

# 2. Faulty Evaporator Fan

The evaporator fan circulates air over the coils. If it malfunctions, the refrigerator may not cool.

Fix:

• Open the freezer and listen for the fan.

• If the fan does not run, replace it.

• Contact an LG refrigerator repair technician if needed.

# 3. Defective Thermostat

The thermostat controls the cooling cycle. A defective thermostat can prevent the refrigerator from maintaining the right temperature.

Fix:

• Turn the thermostat to the lowest setting.

• If the refrigerator does not start cooling, replace the thermostat.

• Seek professional help if the issue persists.

# 4. Low Refrigerant Levels

Low refrigerant reduces cooling efficiency. This problem typically requires professional repair.

Fix:

• If the refrigerator is not cooling but the compressor runs, low refrigerant may be the cause.

• Call an appliance repair San Diego technician to handle refrigerant issues.

# 5. Broken Door Gasket

A damaged door gasket allows cold air to escape, making it harder to maintain temperature.

Fix:

• Inspect the gasket for cracks or tears.

• Replace the gasket if it shows signs of wear.

• Ensure the door seals tightly after replacement.

# 6. Malfunctioning Start Relay

The start relay powers the compressor. If it fails, the compressor will not run.

Fix:

• Unplug the refrigerator and test the relay with a multimeter.

• Replace the relay if it shows no continuity.

• Consult an LG refrigerator repair expert for further assistance.

# 7. Blocked Air Vents

Blocked vents restrict airflow, causing uneven cooling.

Fix:

• Check the refrigerator for overpacked shelves.

• Rearrange items to allow proper airflow.

• Ensure vents are not obstructed by food containers.

# When to Call a Professional

If the refrigerator continues to have cooling issues, call a professional. An appliance repair San Diego service can diagnose and repair complex problems. Regular maintenance and prompt repairs can extend the life of your LG refrigerator and keep it running efficiently.
