Sail Switch 31093MC Atwood AFS MC Enterprises is designed for use with Atwood AFS Series Furnaces.
It plays a crucial role as an air proving device, preventing ignition until it detects 75% of the motor's rpm's.
By confirming the combustion wheel's rotation speed, it guarantees a proper air and gas mixture for smooth ignition.
When pressed down, the switch's paddle should maintain continuity.
If replacing a sail switch, it is important to choose the exact same size.
Common issues with these switches include loose wire connections, bent paddles, or obstructions between the paddle and switch contact.
