I have a goodman gdh80904bxaa heating unit. The control board led is out and will not come on. I have check power to the control board, it seem to be OK, changed the control with a new one, I have the same problem, I checked the heating unit door switch, it seem to be OK, has anyone seen this problem? If so I would like some help. Thank you

First you say "no power to the control board" then " power seems ok ". If the LED is not lit, you have no power to it. Did you check breaker? Power to control board transformer? Thermostat?
