Overview

The Suburban 521232 is a replacement blower motor designed for Suburban RV forced-air furnaces. This 12V DC motor features a dual-shaft design, with one shaft driving the room air blower wheel and the other driving the combustion air wheel. It serves as a direct OEM replacement for Suburban SF-35, SF-42, SFV-35, and SFV-42 series RV furnaces.

When the furnace control board calls for heat, this motor operates continuously. Symptoms of a failing motor can include weak airflow, unusual noises, failure to start, or intermittent operation. This OEM motor ensures proper airflow for safe and efficient heating.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
