The defrost bi-metal thermostat, identified by part number WR50X10070, is compatible with specific refrigerator models from GE, including brands like Hotpoint, General Electric, and Sears-Kenmore. Its primary function is to regulate the evaporator's temperature during the defrost cycle to prevent overheating.
Prior to installation, disconnect the refrigerator from the power source to ensure safety. Consider placing perishable items in a temporary storage solution during this procedure. Wearing work gloves is advised to protect your hands.
