The 31377MC Air Flow Sail Switch from MC Enterprises is designed for Atwood Everest and Excalibur Furnaces.
This sail switch acts as an air proving device and requires 75% of the motor's rpm's before ignition can occur.
Continuity through the switch should be present when the switch paddle is pressed.
Replacing a sail switch with the exact same size is important.
Common issues with these switches include loose wire connections, bent paddles, or obstructions between the paddle and switch contact.
