The Dometic / Hydro Flame 30135 Furnace Motor is a genuine OEM 12‑volt DC heater and furnace blower 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 coach while supplying the airflow necessary for proper combustion, sail switch activation, and reliable burner operation.

Manufactured to original Dometic specifications, the 30135 restores dependable furnace performance when the original motor becomes noisy, develops bearing wear, overheats, experiences intermittent operation, or fails completely. Proper blower motor operation is essential for safe ignition, heat exchanger airflow, and consistent interior comfort.

This OEM replacement motor helps maintain factory heating performance and dependable operation in RVs, travel trailers, fifth wheels, and motorhomes.
