Suburban Furnace 12V DC Motor | 233102 | SF-35 Pre-2001

Restore reliable blower operation to your older Suburban RV furnace with the Suburban 233102 Furnace 12V DC Motor. This genuine Suburban OEM motor is the blower fan motor that circulates heated air through your RV's ducting — the critical component that delivers warm air from the furnace to your living space. When the motor fails, your furnace can light and burn but no heated air reaches the cabin.

⚠️ For Pre-2001 SF-35 / SF-35F Furnaces ONLY

The 233102 fits a specific range of older Suburban furnaces. Compatibility is strict — confirm before ordering:

• Suburban SF-35 furnace
• Suburban SF-35F furnace
• Models built prior to 2001
• Serial number BELOW 012003642

If your furnace is from 2001 or newer, or has a serial number above the cutoff, this motor is NOT the correct replacement. Verify your model and serial number on the furnace's data label before ordering.

Have a Newer SF-35 Furnace?

If your Suburban SF-35 or SF-35F furnace was built 2001 or later, OR has a serial number at or above 012003642, this 233102 motor is NOT the correct replacement. The newer SF-35 furnaces use a different motor — the Suburban 521255 Furnace Motor Kit (for SF-35VHQ / SF-35VHFQ variants). Match the motor to your furnace's model AND serial range before ordering.

Cross-Reference Part Numbers

The 233102 is the direct replacement for two earlier Suburban part numbers:

• Replaces 231707
• Replaces PE26239Q

If your existing furnace motor shows either of those part numbers (or you're cross-referencing from a service manual), this 233102 is the correct successor.

What This Motor Does

The 233102 is the blower fan motor in your Suburban furnace. Its job is critical to furnace operation:

• Drives the combustion air fan that delivers the right air/fuel mixture to the burner
• Drives the circulation blower that moves heated air through ducting into the RV interior
• Operates the sail switch that signals proper airflow before the gas valve opens (a critical safety function)

When the motor fails or weakens, common symptoms include the furnace not igniting (because the sail switch doesn't activate), reduced airflow into the RV, unusual noises from the furnace cabinet, or complete lack of warm air circulation despite the burner lighting.

Common Failure Symptoms

Reasons to replace the existing furnace motor include:

• Motor doesn't spin when called for heat — furnace won't ignite at all
• Motor spins slowly — insufficient airflow trips safety circuits
• Bearing noise (grinding, squealing, or rumbling) from the motor
• Reduced airflow at the registers despite the furnace running
• Motor seizes — completely stops turning
• Intermittent operation — works sometimes, doesn't other times

Genuine Suburban OEM Replacement

As a Suburban factory replacement part, the 233102 is built to original specifications for a precise drop-in fit in compatible SF-35 / SF-35F installations.

⚠️ Professional Installation Recommended

Furnace motor replacement involves opening the furnace cabinet, working around the combustion chamber and gas valve, and verifying proper airflow after installation. Installation should be performed by a qualified RV service technician, especially given the age of these pre-2001 furnaces, where surrounding components may also be aged and need inspection.
