Suburban N Series N30M Parts Diagram · Exploded View › Blower Assembly

Furnace · 4 assemblies · 4 diagram sheets · 90 parts · by Andrew Strick, mobile RV technician

OEM exploded parts diagrams for the Suburban N Series N30M RV furnace: 4 assemblies (Exploded View › Blower Assembly, Exploded View › Cabinet Assembly, Exploded View › Burner Assembly, Exploded View › Combustion Chamber) and 90 manufacturer part numbers. 22 parts are marked as superseded — the description gives the replacement number to order instead.

The rating plate is on the furnace chassis — slide the unit's front panel off or look just inside the exterior access door. Suburban models (SF-30F, NT-34SP …) changed burners and boards over the years, so the serial number's date range matters as much as the model.
