• Helps resolve symptoms like warm fridge/freezer, heavy frost on evaporator, or long/no defrost cycles
• Can cause frequent temperature swings or compressor short cycling if failing
• Typically mounted on or near the evaporator coil in the freezer

• Disconnect power before servicing; defrost ice as needed to access the evaporator area
• Note wire locations; replace using existing connectors or approved splices
• Ensure the thermostat clips firmly to the evaporator tubing in the original location
