Question about Goodman GDS80904BNA Open Flame Heater

1 Answer

Heater problems i have a goodmanGDC8090 force air furnace on the blink (no pun intended). The LED on the circuit board is flashing three times. The troubleshooting manual tells me 4 things it could be. I think i removed the pressure switch hose and blew it out to make sure it was patent. I don't believe i have a blocked flu. I then am not sure how to troubleshoot the pressure switch setpoint or the wiring connection. Could someone please give me some direction and if i need a new pressure switch can i obtain one myself or does it have to come from a service company. Thank you to anyone out there listening, it is getting very cold in my house

That pressure switch closes for a run condition. check for continuity between the plugs on it with the induction fan running. If its closed, change the board if not change the switch.
The switch will tell you its pressure rating on the label and its best to just use the same rating. Easiest to get it from a Goodman Parts Supplier. You can order it on the internet, should have a part number on the label or just use the model and serial of the furnace. Locally you will probably have to buy it from someone in the trade.

Attic fan falure hed light blinking furnace wont run


Sounds like the circuit board needs to be replaced. The exact same thing happened on my house furnace. Power went to the board, producing the flashing led, but stopped there. I believe this is what you mean?

Replace the circuit board.

Does this help? Let us know.

I have a goodman furnace GMP100-4 REV B..about a year ago it was not working. The fan would start but it would not ignite. We found out we need a new ignitor and it was a good quick easy fix. Now a ye


Any light flashin on the control board? If not then look for a small fuse blown on the board. See lights a flashing count them flashes

A sampling of various failure codes on a furnace:

Read one LED flash that stays on continuously to mean your furnace has no signal coming from the thermostat and will not operate. Turn the power off and check the thermostat for improper settings or connections.

Interpret one LED flash that blinks on and off to mean your furnace has locked out because it could not ignite after three tries, and must be reset. Interrupt power to your furnace for 20 seconds or lower the thermostat so your furnace does not try to heat, then reset the thermostat to the previous setting. After one hour of lockout, your furnace will automatically reset itself and try to operate as usual.

Decipher two LED flashes to mean the draft blower is not working, or your furnace has a short in the pressure switch circuit. Turn off the furnace power and repair a short or replace the pressure switch.


Read three LED flashes to mean your furnace has an open pressure switch circuit or it has an induced draft blower operating. Check the pressure switch hose of your furnace for blocks or an improper connection. Also, look for blockages in the flue, and tighten any loose wiring.

Translate four LED flashes to mean your furnace has a primary limit circuit open, possibly from loose wiring or blocked filters. Check and clean filters, tighten wiring and check the flue for blockages.

Interpret five LED flashes to mean your furnace senses a flame without a call for heat. This could be from a gas valve closing slowly or a burner flame lingering.



Read seven LED flashes as a warning of a low flame sense microamp signal. This could happen with a coated flame sensor or a lazy flame from poor gas pressure. Turn off the power and adjust the gas pressure according to the information on the rating plate.



See eight LED flashes as meaning an igniter circuit problem due to a bad igniter or an igniter connected improperly. Replace the bad igniter or check the ground wiring, making necessary corrections.



Decipher nine LED flashes to mean the high-stage pressure switch circuit will not close during a high-stage-induced draft blower operation. Your furnace may have a pinched or blocked pressure switch hose, a blocked flue or loose wiring.

Read continuous flashing on the LED to mean your furnace has a reversed polarity of 115 volts. Turn off the power and correct the wiring polarity after reviewing the wiring diagram.

House heater does not blow hot all the time. the furnace kicks on and then shuts of and then the blower just blows cold air. the furnace tries to kick on three times but shuts off, sometimes it works just...


When it blows cold air, there should be an error code blinking on the LED light located on the PC board. Look through a small viewing port in the front panel, then remove the front panel and on the reverse side there should be a diagnostic code chart to help you figure what is wrong.

Goodman have troubleshooting idiot lights on the board. Look for flashes and count em.
The flash explanations are printed on the backside of the blower cover on most models.

Have a Evcon Coleman Furnace shows three green blinking lights but will not ignight what could be wrong


I have had the same problem with mine for the last 2 years. Remove the motor on the side of the furnace(usually held on by 3 screws) and turn the fan blades inside by hand. after sitting all summer it seems to get stuck. If it moves freely, replace the motor and try to start it again. This fixed mine the last 2 years! Hope this helped.

Furnace shut off after 3 time flame from pilot


Sounds like you may have a weak or bad flame sensor. If the circuit board does not sense a good flame it will not light the burners. Also if your furnace is 5 yrs or newer it should give you a fault on circuit board in the form of a blinking or a code itself.

Goodman GDS8 Furnace Won't Cycle


Sounds like you are on the right track with the plug. Pull the plug apart and check to make sure all the prongs (male and female are correctly snapped into position ...usually its a conductor prong that has been pushed out of place when the plug was put together. I have also seen this problem and could not find a solution, just changed the board and the problem was resolved ( thought it was perhaps a crack in the printed circuit).
I have also seen problems with the connection for the pressure hose on the induction fan clogging up ...pull the hose off and push a very small wire into the hole (with the furnace off of course) and see if it fixes the problem. The fan I ran into the problem with had the connection located low on the housing.
