Any ideas???? It's cold outside (42 degrees), the wife and three kids are home for the day/night and I have to go to work at 1630. The last time I had someone come to look at this unit, they said I needed a new unit, then got a second opinion and an eight dollar part fixed it. Leary of having a "professional" come and look at it as I would have been out about $5,000.00 last time. I can hear the blower going but no warm air, also tried the A/C and nothing either. Thanks

2 blinks = end switch open

Check venter end switch.

ok, checked the end switch and it was stuck open. got it to close and it worked sporadically through the night and day. just replaced the vent motor and the end switch. I can see and hear the switch closing when we turn the heat on, but still no heat. the circuit card continues to have two blinks with the new switch, even when closed.

Did you test the switch on the new vent motor? Turn off the breaker to the unit and wait 5 minutes then turn back on. 2 Blinks on Goodman is the end switch. I looked your unit up so that was not a guess on my part.
