Hotpoint HSS25GFTWW 25.3 cu ft Side-by-Side Refrigerator with Ice & Water Dispenser and LED Interior Lighting MECH-04 Error Fix: Loud Humming, Buzzing, or Clicking Noise

Error code MECH-04 on the Hotpoint HSS25GFTWW 25.3 cu ft Side-by-Side Refrigerator with Ice & Water Dispenser and LED Interior Lighting means: Loud Humming, Buzzing, or Clicking Noise. The refrigerator is making abnormal noises — a loud, repetitive clicking every few minutes usually indicates a failing compressor start relay (the compressor tries to start, fails, and the overload clicks it off); a constant loud buzzing or humming means the compressor is trying to run but is struggling — may be failing bearings or a locked-up compressor; a high-pitched whine or squeal from the back or top indicates the evaporator or condenser fan motor bearings are worn; a rattling or vibrating noise can be the refrigerator touching a wall, the drain pan being loose, or the condenser fan blade hitting something; the evaporator fan motor is in the freezer section behind the rear panel
