Suburban RV Furnace Motor | 521137 | NT-30 M/S/SP | 12V DC

Restore reliable furnace airflow with the Suburban Replacement RV Furnace Motor (Part #521137). Genuine Suburban OEM blower motor for NT-30 M/S/SP furnace models. Compact, high-efficiency 12V DC motor with 5.5A draw.

What This Motor Does

The 521137 is the blower motor in your Suburban NT-30 furnace. It drives the fan that circulates combustion air and pushes heated air through your RV's ductwork. When the motor fails, symptoms typically include:

• Furnace ignites but no air comes through vents
• Loud grinding, squealing, or unusually loud operation
• Furnace starts and immediately shuts off (safety limit trips due to no airflow)
• Slow blower ramp-up or intermittent operation

Compatible Suburban Furnace Models

Direct replacement blower motor for:

• NT-30M
• NT-30S
• NT-30SP

Verify your existing furnace is one of these NT-30 M/S/SP variants before ordering. If your furnace is an SF-series or Q-series (SF-20/25/30/35), this motor is NOT the correct replacement.
