LG linear/inverter compressor fridge not cooling
Rule out demo mode, airflow, fans and defrost first, then use LG's forced-run diagnostic to see whether the compressor runs. If the compressor runs but doesn't cool, or won't start with a good board, it's a sealed-system failure: refer it to LG service or an EPA 608-certified technician and check the compressor warranty.
Before you start
- Unplug before touching fans or boards.
- Inverter boards hold dangerous voltage. Live checks are caution work.
- Linear compressor replacement is sealed-system work: diagnose and refer only.
