coleman 7680c856 needs some help
Posted: Sat Oct 30, 2010 1:22 pm
Hello. Before I get going on my skylights and covering the rear deck, it's gettin chilly out.
The home we bought is a bit older, mostly well upgraded. The furnace is a coleman 7680c856.
It appears ot have all the wires going to the right places according to the wiring diagram on the unit. I have 2 immediate problems:
1: the "fan switch" is missing. I can jumper the two wires and the blower comes on. The system switch of course will turn it all off.
2: even with these wires jumpered and the fan blowing, with the pilot lit, the heater won't turn on at all. It's entirely possible that the fault is with the missing fan switch (though I can't see how).
I plan to order the fan switch today anyway, is there a suggested list of other parts I may want to order as known common problems or a troubleshooting list I can use to check for faulty parts? (I can use a meter, and have a reasonable amount of experience with basic electrics/electronics)
thanks!
