Appliance GrandMasters offers expert LG refrigerator repair in Greenville SC and Asheville NC.
At Appliance GrandMasters, we’ve repaired hundreds of LG refrigerators across Greenville SC and Asheville NC. We’ve seen everything—from quick sensor resets to full compressor replacements. This guide helps you catch issues early, stay informed, and know what to do next.
Let’s start with the basics: what’s going wrong and what you can check on your own.
Possible Causes:
Dirty condenser coils
Blocked air vents
Malfunctioning fan motors
Thermistor or temperature control board issues
What to Try:
Unplug and clean coils (behind or underneath the fridge)
Make sure food isn’t blocking airflow
Verify that doors are sealing properly
If you’ve done these and the fridge still won’t cool, it may be a sealed system issue or compressor failure—time to call a pro.
Causes Could Include:
Clogged or frozen defrost drain
Damaged water inlet valve
Cracked water filter housing
Misaligned drain pan
What You Can Do:
Check for puddles under crispers
Remove rear panel and inspect for ice buildup
Replace worn tubing or cracked parts
Leaks left untreated can cause mold or damage to your floors.
Most Common Reasons:
Freezer not cold enough (should be below 10°F)
Faulty inlet valve
Blocked fill tube
Broken ice maker assembly
DIY Steps:
Check freezer temp
Reset the ice maker (consult your model’s manual)
Inspect water line for kinks or leaks
Some noise is normal. But if your LG fridge suddenly gets loud, something’s off.
Noises to Watch For:
Buzzing = Compressor or fan issue
Clicking = Relay trying to start a failing compressor
Rattling = Loose parts or coils
Humming = Motor may be failing
If you hear noises and notice performance issues, don’t ignore it.
LG refrigerators are known for displaying error codes when things go wrong.
Common Codes:
ER IF – Ice fan not working
F dH – Defrost heater issue
ER CO – Communication error with control board
r dS – Refrigerator defrost sensor error
What to Do:
Try unplugging the unit for 30 seconds
If the error returns, take a photo and call a technician
You’ve done all the right steps. But if the fridge is still acting up, here’s when to get expert help:
Fridge isn’t cooling after basic cleaning
Error codes keep coming back
Ice maker leaks or produces no ice
Loud noises or visible part damage
The unit is over 8 years old and showing multiple issues

A few simple habits can keep your LG fridge running smoothly:

Don’t overload the shelves—air needs to circulate
Wipe door seals monthly to maintain tight closure
Leave an inch of space behind the unit for airflow
