Application
This fan switch is a direct OEM replacement part intended for Williams Comfort Products heating equipment. It controls blower fan operation based on heat exchanger temperature, ensuring the fan turns on once the system reaches 120°F and turns off after the temperature drops by 15°F. This sequencing protects occupants from cold drafts and maximizes heating efficiency.
