232683 Motor for SF-42 SF-42F Suburban

Replaces: 232649

232683 Suburban Blower Motor – 12V DC

Fits SF‑42 & SF‑42F Furnaces • 3‑Inch Motor • Replaces 232649

(For units ABOVE serial number 012305199)

This Suburban 232683 motor is the correct OEM‑style 12‑volt blower/combustion motor for later‑production SF‑42 and SF‑42F RV furnaces. These furnaces transitioned from the earlier 2‑1/2″ motor (233103) to a larger 3‑inch motor, which provides higher airflow to support the bigger heat exchanger and combustion chamber.

The serial‑number cutoff is essential: only SF‑42/SF‑42F furnaces with serial numbers ABOVE 012305199 use this 3″ motor. Earlier units use the 233103 motor instead.

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