When you come across the issue of your LG refrigerator running but not cooling, it can be both puzzling and frustrating. At TheKitchenApplianceDad.com, we understand how crucial it is to get your fridge back in optimal working condition. In this detailed guide, we’ll explore the common reasons behind this problem and provide step-by-step solutions to help you fix your LG fridge without necessarily having to call in a professional.
Before diving into troubleshooting, it’s important to understand how a refrigerator works. Essentially, a fridge uses a compressor and a coolant (usually a refrigerant gas) that circulates through coils to remove heat from the fridge and freezer compartments. Anything that disrupts this process can cause your fridge to stop cooling properly while still running.
Problem: Over time, the condenser coils on the back or bottom of your fridge can accumulate dust, dirt, and pet hair. This buildup can insulate the coils and hinder their ability to release heat, causing the refrigerator to work harder and less efficiently.
Solution: Unplug your refrigerator, locate the condenser coils, and gently clean them with a refrigerator coil brush and a vacuum cleaner with a soft brush attachment. Doing this at least twice a year will help maintain the efficiency of your refrigerator. For a visual guide, you might find this resource from Family Handyman helpful.
Problem: The evaporator fan is responsible for circulating cold air from the coils throughout the unit. If the fan is malfunctioning or obstructed, the fridge will run but not cool adequately.
Solution: Check if the fan is running by listening for it or opening the freezer and pressing the door switch (if applicable). If the fan isn’t working, it may need to be replaced. Refer to your LG refrigerator manual for specific guidance on replacing the evaporator fan.
Problem: The start relay assists the compressor in starting up. If the relay fails, the compressor might not run and, as a result, the fridge will not cool even though it’s running.
Solution: Locate the start relay on the side of the compressor; it may be secured by a clip or screws. Remove it and shake it; if it rattles, this indicates it’s likely defective and should be replaced. You can purchase a replacement from an appliance parts store or online.
Problem: Sometimes, the issue is as simple as incorrect temperature settings.
Solution: Check the thermostat settings on your LG fridge. It should typically be set between 37°F and 40°F for the fridge and 0°F for the freezer. If your settings are too high, adjust them accordingly and allow 24 hours for the temperatures to stabilize.
Problem: Blocked or frozen air vents can also prevent cold air from circulating properly throughout the fridge.
Solution: Ensure that food containers or freezer items are not blocking the vents. You might need to defrost the freezer if you notice a buildup of ice that could be blocking the vents.
A faulty thermostat can fail to regulate the fridge’s temperature properly, leading to cooling issues.
Solution: To test the thermostat, rotate it from the lowest setting to the highest setting and listen for a click. If you don’t hear a click, it’s likely that the thermostat needs replacing.
The compressor is the heart of your refrigerator’s cooling system. If it fails, the fridge will not cool at all even though it might still run.
Solution: Compressor issues are complex and usually require professional intervention. However, if your LG fridge is still under warranty, contact LG customer service for support.
If you’ve tried all the above solutions and your LG fridge is still not cooling, it might be time to call in a professional. This is especially true if you suspect compressor issues or if you’re uncomfortable performing any of the suggested fixes.
Addressing the issue of an LG fridge that runs but doesn’t cool can range from simple fixes like adjusting the temperature settings to more complex issues like a faulty compressor.
