The Dometic / Hydro Flame 30136 Furnace Motor is a genuine OEM 12‑volt DC heater and furnace motor designed for use in select Hydro Flame and Atwood RV furnace systems. This motor powers the blower assembly that circulates heated air throughout the RV while supplying the airflow necessary for proper combustion and sail switch operation.

Built to original Dometic specifications, the 30136 restores dependable furnace performance when the original motor becomes noisy, develops worn bearings, overheats, loses airflow capacity, or fails completely. Proper blower motor operation is critical for ignition, heat exchanger performance, airflow proving, and consistent cabin heating.

This OEM replacement motor helps maintain factory heating performance and reliable operation in motorhomes, travel trailers, fifth wheels, and camper heating systems.
