Furnace · 4 assemblies · 16 diagram sheets · 0 parts · by Andrew Strick, mobile RV technician

OEM exploded parts diagrams for the Dometic Dfl Series RV furnace: 4 assemblies (DFLD40111, DFLD40121, DFLA35211, DFLA40211) and 0 manufacturer part numbers.

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.
