Suburban Nt Series NT12MEC Parts Diagram · Replacement Furnace

Furnace · 4 assemblies · 8 diagram sheets · 78 parts · by Andrew Strick, mobile RV technician

OEM exploded parts diagrams for the Suburban Nt Series NT12MEC RV furnace: 4 assemblies (Replacement Furnace, Exploded View › Cabinet Assembly, Exploded View › Combustion Chamber-blower, Exploded View › Burner Assembly) and 78 manufacturer part numbers. 15 parts are marked as superseded — the description gives the replacement number to order instead.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.
