Check the fuse on the board. It is a 3a automotive fuse. There may be a problem in the control wiring. If the fuse is blown, make sure to find the reason why it blew and repair it. Otherwise you will need a whole bunch of fuses.

Replaced pressure switch, ventor and unit still goes off on pressure switch. 3 flashes


Hello, check the small tubing that goes from the pressure switch to the inducer motor, sometimes it could be loose or blocked therfore not allowing the switch to close. Also, there could be some obstruction in the flue pipe preventing the switch from closing.

My Goodman furnace, model GMS80903BNA, is not working. I removed the back panels and checked the pressure switch. That seems to be working fine. The exhaust inducer spins up, the igniter starts to glow,...


That blinking 3 times is indicating a pressure switch problem. Try checking for water or a blockage in any of the hoses going to the pressure switch or condensate drain. Check the air intake and exhaust pipe for any blockage including any saggs that may hold water. Make sure condensate drain or pump is working. If you get a glow from the igniter, there may be a blockage in the gas valve or piping.

Yes, check for obstructions. However, also check to ensure that you used an OEM pressure switch! See this video for an explanation: Amazon Furnace Parts: http://www.amazon.com/s/?_encoding=UTF8&camp=1789&creative=390957&field-keywords=gas%20furnace%20parts&linkCode=ur2&tag=amznelite-20

Goodman GMP075-3 Random Incomplete startup


If the draft motor starts then shuts right off and then a red light comes on usually means that there is a blockage somewhere. Check the pressure switch line, make sure that it is clear and the hole in the heater that the pressure switch vaccum line runs to is open. If that checks out then make sure that your flue vent cap is on and that it is not pressed down on the flue vent and that the gases can vent properly

Goodman heater not turning on


If your pressure switch is clogging then you need to check the flue pipe make sure it is not rusting. If it is the flue should be replaced and also think about replacing the pressure switch. Check your high limit switch also. If the pressure switch goes sometimes it pops the high limit

You should check the vent cap, it seems like the exhaust is unable to get out. If you exhaust fan was bad the unit would not start at all. And it would never spin
