Safety First: Always ensure the propane supply to your Dometic Sail Switch For Atwood HydroFlame AF/Dometic DF Furnace is turned off. Additionally, disconnect the furnace from all power sources (AC and DC). Locate the Sail Switch: This crucial component is usually situated near the blower motor or combustion chamber. It features a small paddle or 'sail' that responds to airflow. Test for Continuity: Utilize a multimeter set to continuity or resistance mode. Disconnect the wires from the sail switch and place a multimeter probe on each terminal. Continuity indicates the sail switch is functioning properly. If not, it may be faulty. Manually Activate the Sail Switch: Simulate airflow by closing the sail switch by hand. Recheck for continuity. If it now shows continuity, the sail switch is in good working order. Replace if Necessary: If the sail switch fails the tests, order a new one compatible with your specific furnace model. Reconnect and Test: Reattach the sail switch wires, restore power to the furnace, and test the furnace to ensure proper ignition and warm air flow.
