Suburban Nt Series NT30SP Parts Diagram · Exploded View › Blower Assembly

Furnace · 5 assemblies · 10 diagram sheets · 124 parts · by Andrew Strick, mobile RV technician

OEM exploded parts diagrams for the Suburban Nt Series NT30SP RV furnace: 5 assemblies (Exploded View › Blower Assembly, Replacement, Exploded View › Cabinet Assembly, Exploded View › Burner Assembly, Exploded View › Combustion Chamber) and 124 manufacturer part numbers. 29 parts are marked as superseded — the description gives the replacement number to order instead.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.
