How to Fix lg fridge light on but not cooling Step-by-Step Guide

Follow these steps to troubleshoot your LG fridge:

1. Check the Power Cord: Ensure the fridge is plugged securely into a working outlet. Try a different outlet to rule out outlet problems.
2. Inspect the Thermostat: Make sure the thermostat is set to the correct temperature. Try lowering it to see if the fridge starts cooling.
3. Clean the Condenser Coils: Locate the coils (usually on the back or bottom of the fridge) and clean them with a vacuum cleaner or brush.
4. Listen for the Compressor: The compressor should be running intermittently. If you don’t hear it, it could be a sign of a problem.
5. Check the Evaporator Fan: Open the freezer and listen for the fan. If you don’t hear it running, it might be blocked by ice or malfunctioning.
6. Examine the Door Seals: Check the seals around the fridge and freezer doors for cracks or damage. Replace if necessary.
7. Defrost the Fridge: If there is excessive frost buildup, manually defrost the fridge by unplugging it and leaving the doors open for several hours.
8. Check Air Vents: Make sure the air vents inside the fridge and freezer aren’t blocked by food items.
9. Reset the Fridge: Unplug the fridge for 10-15 minutes, then plug it back in. This can sometimes reset the system.
10. Inspect the Start Relay: The Start Relay usually is connected to the compressor and a faulty one will cause the unit to not start the cooling process.
11. Check the Overload Protector: Is a switch that prevents the compressor from overheating and getting damaged.
