Coleman OEM 7975-3281 Furnace Fan Switch | F120 Long Auto Reset Replacement (Replaces 4066-3281)
Product Description
Restore proper blower operation with the Coleman OEM 7975-3281 Furnace Fan Switch. This genuine OEM F120 Long automatic fan switch is designed to control the furnace blower motor based on plenum temperature, helping ensure efficient airflow and proper heating system performance.
The 7975-3281 automatically closes its contacts as the furnace warms to start the blower motor and opens them as the furnace cools to shut the blower off. This timed operation helps improve comfort, prevents cold air from circulating during startup, and extends the life of heating system components.
Manufactured to Coleman and York OEM specifications, the 7975-3281 replaces the older 4066-3281 fan switch and is commonly used in select Coleman, Evcon, and York oil and gas furnaces. Its long sensing element allows accurate temperature monitoring within the heat exchanger compartment for dependable blower control.
Always disconnect electrical power before servicing your furnace and verify your furnace model and part number before ordering.
