Suburban 350208 Combustion Wheel – Fix Noisy or No-Airflow RV Furnace (NT-16SQ / NT-20SEQ)

Product Overview

Is your RV furnace making a loud noise, not igniting, or barely pushing air? The issue is often a worn or damaged combustion (blower) wheel.

The Suburban 350208 Combustion Wheel is a direct replacement designed for NT-16SQ, NT-16SEQ, NT-20SQ, and NT-20SEQ furnaces, restoring proper airflow needed for ignition and efficient heating.
