A sail switch for Atwood / Dometic furnaces is provided.
An air proving device, the sail switch is a safety component that will not allow ignition until it detects 75% of the motor’s rpm’s.
It ensures that the combustion wheel is rotating fast enough for a proper air and gas mixture for smooth ignition.
Replacing Dometic 33081, it includes Sail Switch 33063 (flat blade style) and an upgraded sail switch bracket (model applicability specific).
