I have a 73 GMC MH and the furnace won"t work. The pilot is on and the
fan works but the main burner doesn't come on, only cold air. The
furnace looks like the original equipment. It is a slide in type,
Suburban Model NT 32 G, Code GAG, 30000/24000 BTU/hr. I suspect I have a
bad Thermocouple, but have also had some problems with pilot going out
and the fan is pretty noisy and I suspect the bearings are pretty worn.

Questions:
1. Can I get a replacement thermocouple, like from a local RV place,
Cinnabar, Golby etc.?

2. Can I get a better or exact replacement unit for the entire furnace?

3. It would be nice to have a quiet unit without a fan or a very small
fan but I am a little skeptical about the 8000 btu/hr catalytic
models.Would it be big enough? Would it distribute heat well enough? Do
I need to get a vented model? If I put it on the wall to the left as I
enter coach I will lose a lot of the pantry cabinet.

Appreciate any advice before I start calling around after the
weekend.
