LG Refrigerator Troubleshooting
Top Freezer Cold but Bottom Fridge Not Cooling
Fridge Not Cold but Light Is On
Common reasons:
Blocked air vent or duct
Faulty evaporator fan
Defective lower compartment sensor
Try this first:
Clear out both top and bottom sections for better airflow
Listen for fan sound near the freezer
Manually defrost by unplugging for 6 hours
➡️ If the bottom still doesn’t cool after that, it might need sensor or fan replacement.
Possible causes:
Gas leak or low refrigerant
Faulty fan motor
Broken temperature sensor
Main PCB failure
What to try first:
Unplug the fridge for 10 minutes and plug it back (soft reset)
Listen for fan sound inside the fridge
Check if there's ice buildup in the freezer
➡️ If everything seems normal but the fridge is still not cooling, it may be a compressor or sensor issue.
Water Leaking Near Vegetable Tray
Likely causes:
Clogged defrost drain
Ice buildup due to frequent door openings or loose door seal
DIY Steps:
Remove vegetable box and check for standing water
Access the drain hole behind the box → gently blow or use warm water
Use hair dryer to melt any blockage in the defrost drain
➡️ If the leak returns the next day, it might need full disassembly and deep clean.
