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?

No, just two.

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

Thanks, I'll try it out.

Please let us know what you find and how it works.

That wasn't the issue.

Are you still getting the 3 blinking LED light?
