Supco 18805 Refrigerator Freezer Fan Switch

Product Description

The SUPCO 18805 is a direct-replacement fan switch designed for residential refrigerator and freezer applications. This switch controls the evaporator or condenser fan motor circuit, cycling the fan on and off in response to door or temperature conditions depending on the unit's design. It is manufactured to meet or exceed OEM specifications, making it a reliable choice for appliance repair technicians and knowledgeable DIYers who need a drop-in replacement without modifying existing wiring or mounting hardware. The compact form factor - approximately 0.98 inches on each side - fits tight equipment compartments common in household refrigeration units.

This fan switch is suited for residential refrigerators and freezers where the original Gem 18805 or 188-5 switch has failed or shows signs of wear. Common failure symptoms include a fan that runs continuously, fails to run, or does not respond correctly to door opening and closing. Appliance service technicians install this part during routine refrigeration system repairs to restore proper fan cycling and maintain cabinet temperature stability.
