Refrigerator Troubleshooting
Refrigerator troubleshooting guides, starting with the most common complaint: not cooling. Work through the freezer-vs-fridge check first — it splits most cases into a simple airflow fix or a deeper condenser-side problem — then branch into brand-specific error codes where available.
Common Refrigerator Problems
Refrigerator problems split on one question: is the freezer still cold? If the freezer is cold but the fridge side is warm, cold air isn't making it through. That's usually a blocked vent, a frosted-over evaporator or a stalled fan. If both sections are warm, the unit isn't getting rid of heat. Start with the condenser coils and fan, and only suspect the sealed system once those check out. On an LG, work through these basics first, then rule out Demo Mode, then check the display for a fault code.
Choose by Symptom
Open both doors. Is the freezer cold while the fridge is warm, or are both warm? Your answer tells you which half of the guide to follow.
Start troubleshootingSafety First
Unplug the fridge or switch off its breaker before touching the condenser coils or taking off a rear panel. If anything points to a refrigerant leak, stop there. Sealed-system work needs certified equipment.
