Hisense Refrigerator Temperature Fuse 1418420

OEM Hisense temperature fuse, categorized by the authorized parts source as a refrigerator thermal-fuse/breaker part.

Is This the Right Part?

Common Symptoms

• Defrost-system fault requiring confirmation of the fuse bundle and heater circuit.
• Excess ice/frost that obstructs cold-air flow and can prevent normal refrigerator operation after a defrost-circuit problem.

Check Before Replacing

• Disconnect refrigerator power before accessing or electrically testing the part.
• For the applicable RF20N6ASE service configuration, check both fuses in the fuse bundle with a digital multimeter; an open reading indicates the complete fuse bundle should be replaced.
• After any repair, restore power and verify the defrost heater only using the manufacturer-specified service test for the exact model; the heater becomes extremely hot during that test.

Pro Tip

Part Details

Key Features

• Genuine OEM Hisense part number 1418420.
• Officially described as a Temperature Fuse and categorized as a refrigerator thermal-fuse/breaker part.
• In the RF20N6ASE service bulletin, 1418420 is identified for the orange-to-orange and gray-to-gray temperature-fuse pairs in the fuse bundle.
• The affected-model service bulletin places the replacement/relocated fuse near the top of the evaporator coils.

Installation Notes

• Disconnect power before service; do not defeat or bypass the safety fuse.
• For the RF20N6ASE bulletin-specific repair, replace the complete fuse bundle when either fuse is open, then locate and secure the new fuse near the top of the coils.
• Reconnect all disconnected fan and freezer-sensor wiring and ensure panels, drawers, and door gasket are fully reinstalled and sealed before returning the refrigerator to service.
• Allow the unit to be completely defrosted when ice is blocking airflow; residual ice can keep the refrigerator from resuming normal operation.
