521067 Suburban RV Furnace Motor 12V DC NT-16 20SQ

OEM blower/combustion motor for Suburban NT‑series furnaces

This Suburban 521067 motor is the factory‑style replacement used in NT‑16 and NT‑20SQ RV furnaces. It drives both combustion air and cabin‑circulation airflow, making it essential for proper ignition, heat exchanger performance, and safe furnace operation. When the original motor becomes noisy, slow to start, or fails to reach proper RPM, this OEM‑spec motor restores correct airflow and reliable heating.

The motor matches the original Suburban mounting pattern, shaft length, rotation, and electrical characteristics for a direct, no‑modification installation.
