The Dometic / Atwood 30758 Furnace Motor is a genuine OEM 12‑volt DC blower motor designed for Hydro Flame and Atwood RV furnace systems. This motor powers the blower assembly responsible for circulating heated air through the furnace and RV duct system while also providing the airflow necessary for proper combustion and sail switch operation.

Manufactured to original Dometic specifications, the 30758 restores reliable furnace operation when the original motor becomes noisy, develops bearing wear, overheats, experiences intermittent operation, or fails completely. Proper blower motor performance is critical to furnace ignition, airflow proving, heat exchanger operation, and overall heating efficiency.

This OEM replacement helps maintain factory heating performance and dependable cold‑weather comfort in RV applications.
