Hotpoint HPS18BTHBB 18 cu ft Top Freezer Refrigerator with LED Lighting and Humidity-Controlled Crispers MECH-05 Error Fix: Runs Constantly — Never Shuts Off

Error code MECH-05 on the Hotpoint HPS18BTHBB 18 cu ft Top Freezer Refrigerator with LED Lighting and Humidity-Controlled Crispers means: Runs Constantly — Never Shuts Off. The compressor runs almost continuously without cycling off — the most common cause is dirty condenser coils; on Hotpoint refrigerators, the condenser coils are located at the bottom rear or underneath the unit and accumulate dust, pet hair, and kitchen grease over time; dirty coils cannot dissipate heat efficiently, so the compressor works overtime; clean the coils every 6-12 months with a coil brush and vacuum; other causes include a worn door gasket allowing warm air to leak in, the temperature control set too cold, the door being opened frequently, a frosted-over evaporator (defrost problem), or low refrigerant charge from a sealed system leak
