I have a goodman gmpn080-4 gas furnace. I have put in a new breaker, new wiring to furnace from breaker box, and also tried jumping red and white wires at thermostat and at furnace. LED does not come on at all and furnace was working when I left for work this morning. Any suggestions before calling a professional? Thanks

Check the blower door switch. It is a interlock switch and they do go bad.

I bypassed that switch and switch on the side of the furnace still nothing. Thanks for the fast response.

Is the 120 volts going to the circuit board. Test for voltage at the circuit board 120 volt feed wires. Also check to see if there is a fuse blown on the circuit board.
