Suburban Furnace Motor | 521067 | Fits NT-16SQ/20SQ | 12V

Restore reliable blower operation to your Suburban NT Series RV furnace with the Suburban 521067 Furnace Motor. This genuine Suburban OEM 12V DC 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, the furnace can light and burn but no heated air reaches the cabin.

For Suburban NT-16SQ and NT-20SQ Furnaces

The 521067 is specifically engineered for two Suburban NT Series furnace models:

• Suburban NT-16SQ
• Suburban NT-20SQ

Verify your furnace model on the manufacturer label before ordering — Suburban makes multiple furnace motors, and they are not interchangeable across different furnace model series.

Have an NT-16SEQ or NT-20SEQ Instead?

If your furnace is an SEQ variant (NT-16SEQ or NT-20SEQ) rather than an SQ, this 521067 motor is NOT the correct replacement. The SEQ variants use a different motor — the Suburban 521068 Furnace Motor. The SQ vs SEQ designation is a small but important detail — verify the exact model designation on your furnace's manufacturer label before ordering.

What This Motor Does

The 521067 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 521067 is built to original specifications for a precise drop-in fit in compatible NT-16SQ and NT-20SQ furnaces.

Easy Installation for Routine Maintenance or Repair

The 521067 installs as a direct drop-in for the original motor — no modifications required. The motor mounts to the existing furnace housing with the original hardware and connects to the existing wiring via the standard 12V DC connection.

⚠️ 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 if your furnace is aged and surrounding components also need inspection.
