Guide · RefrigeratorFirst decide if it's really a problem. Whirlpool says 40-80% run time is normal at average room temperature, and newer variable-speed compressors are designed to run long at low speed. If it's truly excessive, the usual causes are heat-rejection problems (dirty condenser, dead condenser fan), air leaks (gaskets, doors) and a frosted evaporator. A compressor or refrigerant fault is a referral.
Guide · RefrigeratorRule out settings, demo/cooling-off mode and airflow first, then confirm whether the compressor and condenser fan run. If the compressor is running but nothing gets cold, or it won't start even though the start components and power check out, it's a sealed-system problem and goes to an EPA 608-certified tech.
Guide · RefrigeratorRule 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.
