Goodman gms950703bxa stuck in lockout
I have a Goodman gms950703bxa furnace that is stuck in lockout. According to the manual it is supposed to clear it's self in 1 hour. The led comes on blinks once and then returns to the steady on condition. The furnace will not start. i have checked all the wiring, tested all the sensors, checked polarity of the AC. I had to re-route the gas line so I also purged the gas line by powering up the gas valve so I know that works. Also the igniter is good. The gas valve never opens to start the start-up sequence. I was wondering if there is a way to force the lockout to clear? Any help will be greatly appreciated.
