    Goodman GDH80904BX: No power to draft inducer
    I'm having an issue with my Goodman GDH80904BX. It is not getting power to the draft inducer.

    I'm getting 3 blinks indicating that there is an issue withthe pressure switch. I've checked to seeif the pressure switch is stuck in the closed position, and it isn't. I've put a vacuum on it and it closed thecircuit, and when vacuum released the circuit opened. While the pressure switch is hooked to thesystem, when a vacuum is put onto the pressure switch, the light goes to solidon. Once the vacuum is taken away, thelight continues to blink 3 times.

    I've also checked to see if the C to W are getting goodcurrent, and it is.

    Does anyone have any suggestions of what I can check next?

    Hi abc and welcome, this wouldn't happen to be a three wire pressure switch would it?

    Condensate build up in the vacuum lines, or clogged vents?
