Surburban furnace

[john massey]

Thanks, John

I'll see if I can get a parts manual.

BTW When I tried to start the furnace by setting the thermostat, I heard
no click, no blower, nothing. While I was on the net looking for
information, my wife looked at our 1977 Cobra van conversion and saw
that it had a Suburban furnace also and it works. I pulled the cover off
the Cobra's thermostat and saw that a reed relay clicked in when the
thermostat setting was changed.

I went over to the GMC, pulled the thermostat cover, moved the setting
lever and the reed relay didn't move.
I touched the relay arm, it moved, clicked the relay closed and the
blower came on with the heat a few minutes later. Whew...it all works
now.

Glad it works now, btw: that HARD TO FIND parts catalog is available
at Camping World, and had a 5.00 price on it. I,ve found it a good
investment, We've had our 73 for a little over 9 years, and have found
its well worth doing research early, before something breaks.
