Looking for a burner for our Suburban furnace. Our coach has 3, and one at this time is in need of a new burner. The Model is NT-24md, and the part # is 180215. Tired of the "google searches" maybe someone knows of a better place to check. Winter is coming soon, and the heat sure helps when your traveling through Wi and MN!:)

Welcome "rodey"! Steve Ward (Prarieschooner) will probably chime in soon. He has had to do some repairs on his furnaces and I believe he has a source for parts.

Also welcome "rodey"! I took both (NT-30M & NT-16F) of our Suburbans apart cleaned and replace/repaired control boards, and other parts. I found adventurerv.net to have a lot of the older as well as newer parts. The "Burner Orifice" you listed is common to NT-24 M/S/SP and NT-25 furnaces, and is listed in their parts manual http://manuals.adventurerv.net/Suburban_RV_Appliances_Parts_Manual.pdf Good Luck on your repairs, should you need any additional information don't hesitate to contact me.

Welcome rodey. Here is a link to that part;

I have bought from this supplier before and have had real good luck. Here is a link to a previous post about these Suburban Furnaces and some repairs, mine has some part numbers as well;

On our '82 we have a NT-16L in the Saloon (Living Room) and it supplies Heat to that area as well as the Tankage Bay, a NT-16L under the Refrigerator and it supplies Heat to the Stairwell and the Tankage Bay, and then we have a NT-24M under the Street Side Closet and it supplies Heat to the Bedroom area. Since you are discussing the NT24 I suspect that you are working on the one in the Bedroom.

Hopefully you only need the Burner Orifice because this looks readily available and inexpensive. While you are in there you should replace the Switch that Tells the Heater that the Ducting has Cooled Down so that the Fan Turns Off, it was only about $20.00 and was readily available as well. I was able to take a Stainless Steel Brush (Toothbrush) and Clean my Burners and Orifice. When you look through the Sight Glass you should see a Blue Flame and not a Yellow Flame.

Finally, please get a Carbon Monoxide Alarm! they are not expensive and make really good sense since our Heaters are Older and the Flame Box could Fail.

PS, The Dinosaur Board (replacement) has a different circuit for lighting the burner than the original Suburban Board. The Dinosaur Board attempts to light the burner a few times before shutting the system down. I found this out after replacing that board in one of my units, the unit operated much better with the new board as well.
