Possible Thermostat problem???

[al_in_cedar]

okay, i searched the forums and didn't find an answer to this question...

FIRST: Im a newbie.. let me get that out of the way... I just picked up a real nice 1985 Sunline T-1350. It's exactly what I've been looking for and in very good shape. ($900)

Here is the problem.. I KNOW the furnace works(ed). I can light the pilot light and have actually had it fired up and had it heating. However... I kind of tapped on the thermostat a couple of times and the heater stopped heating.

Here is what I can tell you:
1. the pilot light is lit and is very easy to light and STAYS lit.
2. the stove works fine.
3. the fan kicks on when I want it too and turns off as it should.

the only thing missing is the FLAME part which provides the HEAT part.

I am thinking that the thermostat stopped working when I 'tapped' on it. Although there isn't much to it, I dont know anything about it...

Anyone out there that can throw this newbie a bone and tell me what to try? If it's just the thermostat, i'll run out to the thermostat store tomorrow, but I need some input from the pro's...

All in all, I'm real happy with my purchase and I think I have a real nice box..

THANKS IN ADVANCE
