Copeland Comfort Control (White Rodgers) 3F01-180 Snap Disc Fan Switch 180°F Cut-in 160°F Cut-out Auto Reset Close on Rise

The Emerson Climate-White Rodgers 3F01-180 Snap Disc Fan Control manages fan operation by responding to temperature changes within equipment. This control activates or interrupts the fan circuit when specific temperature points are reached during operating cycles. It operates through a temperature-sensitive disc mechanism with a 3/4" size, 180F cut-in, and 160F cut-out ratings to regulate switching action. The component is mounted on compatible heating equipment and HVAC systems during service or replacement work. It helps coordinate fan cycling and supports proper temperature-based control operation.
