233101 Suburban Blower Motor 12V DC SF-20/25/30 SF-20/25/30F (2 1 2 INCH MOTOR)

Replaces 231706

Fits SF‑20, SF‑25, SF‑30, SF‑20F, SF‑25F, SF‑30F Furnaces

The Suburban 233101 is the OEM‑spec 12‑volt blower/combustion motor used in the SF‑series RV furnaces. These furnaces rely on a compact 2‑1/2 inch motor to deliver both combustion air and heated‑air circulation. When the original motor becomes noisy, slow to start, or fails to reach proper RPM, this replacement restores correct airflow and reliable ignition performance.

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