350198 Suburban RV Room Air Blower Wheel

Furnace Models: SH-35 42 SH-35 42F

The Suburban 350198 Room‑Air Blower Wheel is the OEM warm‑air circulation wheel used in SH‑series RV furnaces. This wheel mounts to the heated‑air side of the blower motor and pushes air across the heat exchanger and into the RV’s ducting system. Proper airflow is essential for maintaining furnace efficiency, preventing overheating, and ensuring smooth, quiet operation.

A worn, cracked, or unbalanced wheel can cause weak airflow, vibration, excessive noise, or high‑limit trips. Replacing it with the OEM 350198 restores factory‑rated airflow and reliable performance in SH‑series furnaces.
