Genuine Dometic OEM dual-shaft blower motor — drives both the blower wheel and combustion air wheel. 12V DC, 7.6A full load. For Dometic Hydro Flame 8525-IV and 8531-IV furnaces. Direct replacement for motor part number 37697.

What This Motor Does

The furnace motor is the dual-shaft drive component attached to both the blower wheel AND the combustion air wheel. When the control board sends power:

• Motor starts operating and rotates the drive shafts
• Blower wheel circulates heated air through the coach ductwork
• Combustion air wheel provides intake air for the burner and vents exhaust

When the motor fails, symptoms typically include no airflow through vents, loud grinding/squealing operation, furnace shutting off shortly after ignition (safety limit trips due to no airflow), or slow blower ramp-up.

⚠️ Correct Motor Size is Critical

Important sizing note: motor size and RPM correspond directly to the furnace BTU/hr rating — installing an incorrect-size motor will cause furnace performance issues or safety fault trips. Verify your existing furnace model matches the compatibility list before ordering.
