Goodman furnace GMP 075-3 Burners will not ignite
I have a Goodman GMP 075-3 furnace that will not ignite. I have checked the hose to the pressure switch, and all the limit switches. I have four of them and they all register good. I even tried jumping them out. The igniter comes on and glows, but when the gas valve is supposed to open it does not and the igniter goes back out. This cycle is repeated and nothing happens. The red light on the circuit board has a continuous glow, no flashing. The only thing that I can come up with is that the gas valve is bad. I have read some of the prior questions from others and tried some of the suggestions offered, still nothing.
