Suburban Furnace Motor Kit | 521255 | SF-35VHQ | SF-35VHFQ

Restore reliable furnace airflow with the Suburban Furnace Motor Kit (Part #521255). Genuine Suburban OEM blower motor kit engineered specifically for SF-35VHQ and SF-35VHFQ models. Current OEM replacement for the discontinued Suburban 521232 motor.

Current Replacement for the Discontinued 521232

The 521255 is the current OEM path forward from the discontinued Suburban 521232 furnace motor. If your existing motor is a 521232 and you can't source the exact match, or you're ordering fresh replacement stock, the 521255 is the current replacement.

What This Motor Does

The furnace blower motor is the heart of your furnace's airflow system. When the furnace control board sends power to the motor, the shaft(s) rotate the blower wheel and combustion air wheel to:

• Circulate heated air throughout the RV
• Draw combustion air into the burner

Motor failure results in complete furnace shutdown — without airflow, the safety systems prevent burner ignition.

⚠️ Specific Furnace Model Compatibility

This motor kit is engineered specifically for:

• Suburban SF-35VHQ
• Suburban SF-35VHFQ

Verify your existing furnace matches one of these model designations before ordering.

Smaller BTU Furnace?

For Suburban SF/SFV furnaces at 20K, 25K, or 30K BTU, this 521255 is NOT the correct motor. Use the Suburban 521230 Blower Motor instead — engineered for SF-20/25/30 and SFV-20/25/30 series.

Design and Performance Features

• Compact design — fits seamlessly into the Suburban SF furnace
• Easy installation — straightforward setup
