Goodman Furnace Pressure Switch
When my furnace tries to come on it blinks 3 times which tells me my pressure switch failed to close. I went and got another one and put on and it is still doing the same thing. When I jumper it out the furnace comes on and works normally. I checked the vent and it is free of debris. Is it possible my new pressure switch is defective or could it be something else? Now this past summer I did accidentally spill a cup of apple juice down my living room vent, but if that was a problem then the furnace wouldn't have came on a couple weeks ago. Any help is greatly appreciated!
