RV Repair: wiring between Coleman Thermostat and Furnace, happy camping, thermostat

Question
Darren:

Had some problems with my Suburban SF-35 furnace going out and restarting.  Was advised to take it out and blow out any residue.  When I did that, one of the wires came loose and I'm not sure where it goes.  It is a white wire from the thermostat and I have it attached to one of the blue wires from the furnace now, however, the furnace will only run on manual operation...not with setting the thermostat.  The wires that are visable from the furnace are: 3-blue...1-red...1-yellow and 1-white.  The thermostat wires a the furnace are: 1-white...1-yellow and 1-red.  Any suggestions?

Thanks

Answer
Don,
   There should be 4 wires at the furnace.  Red 12volts+, yellow 12volts-, and 2 blue that go to the thermostat.  From the thermostat you should have a red and white wire which hook 1 each to the 2 blue wires at the furnace.  I hope this helps, good luck and happy camping.
