ok here is the deal.
I have a suburban nt-24 that will not light when I am at 8000+ ft....the confusing part is it used to. :-\
what originally happened was that it was running perfectly and the wall thermostat decided to die on me. It was my last trip of the season so I took the camper down to my house at 3500ft. replaced the thermostat and it fired right up. The following season I took the camper back up to the mountains ( around 8200ft) and it goes through all the motions. Fan kicks on, sail switch activates, igniter sparks, you can smell propane but no ignition.
since all of this I have replaced the following
1. sail switch
2. limit switch
3. control board
4. igniter
5. regulator on the camper
6. cleaned all the intake and exhaust tubes.
Everytime I Bring it home (3500 ft) it fires right up on 12v without shore power. also has new batteries and full propane tanks.
I am at a loss and can not think of anything else to replace or clean. seems to me its a mixture issue but again intake and exhaust are clean and regulator is new and bottles are full. hopefully someone out there has an idea for me.
Thanks in advance.
