    There should be a wiring schematic on the inside of the front cover, this should show you what goes where. If you don't know how to read a wiring schematic, please take a clear picture of it and post it here. Should be able to help you out.

    Post the model of the unit so I can see if I can find a wiring diagram. I cannot read the one you posted. You posted a Nordyne wiring diagram but in your first post you said Coleman?

    Our Coleman Heater will ignite and you can hear the clicks sent from the thermostat, but the fan won't start. We tried a combustion air switch, but now think it is the combustion fan?? Please help.
