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 · RefrigeratorLG's own help library describes this pattern on its refrigerators: meltwater from the defrost cycle cannot reach the drain pan because the freezer drain is blocked by ice or debris, so it runs back and freezes on the bottom of the freezer. LG's first step is a full manual defrost; if the ice returns, LG says a technician should clear the drain, which requires disassembly. Repair sites and forums report it repeatedly on LG bottom-freezer and French-door models.
Guide · RefrigeratorOn Sub-Zero units the condenser sits behind the top grille (or the kickplate on undercounter models) and loads up with dust and pet hair; the service indicator generally means a compressor is running too long to hold temperature. The common wrong turn is quoting a sealed-system repair or a board before the condenser has been properly cleaned, the condenser fan confirmed and the unit given a full day to recover.
