Dometic Digital Thermostat - Furnace Control Only - White

Question:

I have an Atwood model DCLP 1522 furnace in my Lance camper. It is a discontinued two speed furnace that requires a special thermostat that is also no longer available. The thermostat is now dead so I am looking to change to a single speed furnace with a simple thermostat. I noticed you have a 20,000 btu unit with exterior access door which is similar to what I currently have. Is this the smallest btu propane furnace available? I am currently investing the actual ability to do the change as access is pretty much non -existent. Also, what thermostat would you recommend for a single speed thermostat? Thanks!

Hey Greg, yes our Dometic RV Furnace part # DMC86RR is our lowest BTU rated RV furnace. Thankfully nearly all RV furnaces are made to the same size which makes swapping them easier.

For a thermostat we have the Dometic Digital part # DMC84RR which is a furnace only style thermostat that would work great.

Hey Greg, how did things go with the Dometic furnace and digital thermostat swap in your Lance camper? Were you able to work around the tight access you mentioned? Your update could make it easier for others facing the same challenge.
