The Atwood 31094 is a small, white sail switch kit designed for compatible RV furnaces. This low-airflow safety switch detects air movement from the furnace blower and helps ensure proper operation of the heating system. It is listed for several Atwood Hydro Flame furnace models. Compatibility may depend on the furnace model and serial number, so compare the original switch and consult the furnace parts list before ordering.
