Goodman GMP100-3 Forced air furnace
ok, back with a new issue.
so i have an intermittent issue, the house seams to stay at the temp but every once in a while my furnace wont work until i reset it and right now that is not fixing it. the fan turns on, the igniter turns on, gas doesn't light. cycles 3 times then shuts down and blinks one time. once in a while the gas will ignite for a couple seconds then shut down with the same error. I am at a loss with this one, i cleaned the flame sensor but that is obviously not the issue because the flame is not turning on.
any ideas before i have to spend more moeny than i can afford to have a pro look at it?
