I have a Comfortmaker furnace Model GNJ100N12C1 to be exact that will not turn on. We turn the thermostat to auto nothing turn it to fan nothing.

Sounds like no 24 volt control power, see if there is a fuse in the circuit board of the furnace, see if door switch on furnace is made(pushed in) this switch is in the blower section and pushs against the panel door. Good luck, Mike

There is a fuse and we took it out put a new one in. We also had push the switch in and ran a wire and tried jump starting it (to make sure that it wasn't the switch) Still nothing.
