Question about Goodman GMS90703BXA Heater

1 Answer

Goodman GMP 100-5 Rev B Serial # 9902602550 The status light stays illuminated. It isn't blinking. I believe my igniter went bad. When I turn on my heat on the system, The exhaust fan kicks on, goes a few seconds, then the gas turns on, but does not light. Then the gas turns off. I was able to light the furnace with a long lighter (like a disposable kind) and it heated up like it was suppose to. I pulled the igniter, and it appears to look fine,can these just go out? Where can I get one of these?

Hello, the first thing is check the igniter for any crack or white spots on it, also, if you have a multimeter check the resistance of the igniter, should be between 40-90 ohms. You can purchase a igniter at any Heating and Cooling supply store.

    Igniters typically should last a few years but if they are exposed to dirt or anytype of moisture it can shorten the life of it.

No heat from furnace, Goodman GMPN080-4 Rev A. Cycle is solid red status light, then 3 flashes indicating open pressure switch because the inducer fan does not come on.


Jimbo, it sounds like you are aware of the operational sequence to suggest using a voltmeter to check the actual wires going TO the combustion air fan...if there is no voltage from the board, the board is bad. Just make sure one of the high temp limits are not open... one may be in the blower compartment on some and one will be near the top of the vestibule and a roll out switch should be near the burners. They should all be wired in series.

Always check the manual reset safty switches as the first step in troubleshooting.

Goodman GMP Furnace problem. Original problem is


Good one! Is the flame getting to the flame sensor within the few seconds? Maybe a good cleaning of the burners or flame tray would help. 1.3 ma is enough for the flame rod to tell the board to stay on. Re-do all the ground connections both at the board and furnace cabinet to be safe. Check the polarity of the power going to the furnace. What are the chances the second board is bad?

Goodman GMP 125-4 one blinking light code. Gas valve has been replaced (at cost of $443). Didn't fix problem. Same co wanted $415 to replace circuit board. I did it myself for $99 part. Still same problem!...


One blink means it didn't light after a number of attempts. You replaced the circuit board and gas valve. Read on for some suggestions. On a call for heat, the 24 volt thermostat sends a signal to the control module. The control module will indicate a call for heat with a light on the control either blinking or remain solid depending upon model. The inducer (exhaust) blower will purge all gasses from the furnace and pressurize a pressure switch. Once the pressure switch tells the module to continue, the electronic ignition will energize and send 120 volts to the igniter. The igniter will glow and you will be able to see it if viewed thru the small inspection port. Once the igniter gets hot enough, it sends a signal to the module opening up the gas valve (24 volts). Either a pilot will come on or the burner tube will ignite then spread the flame to all burners. Lastly a safety sensor will be looking for a certain temperature within a few seconds and the furnace will continue to operate and the room air blower will turn on in a minute or two.

What could go wrong? The unit will not run if there is no signal from the thermostat (bad thermostat or broken wire), the control module does not sense a signal from the thermostat (bad control), the inducer does not energize (bad motor), the pressure switch does not close (blocked vent piping, bad switch, plugged condensate hose), the igniter does not energize (bad control, bad igniter), the gas valve does not open or there is no gas (bad gas valve, broken wire, no gas), the pilot does not light (dirty pilot), the burner does not light (bad burner, plugged orifice, not enough combustion air), the flame does not spread to each burner (bad flame spreader, dirty flame spreader, more bad burners), the flame safety sensor does not detect flame (dirty or bad flame spreader, bad flame sensor, broken wire, bad control), or the room air blower does not energize (bad fan motor, bad control).

Goodman GMP075-3 Has 1 single blink on the light


The blink codes are differant on every furnace. Read your code on the schematic found on the inside of the door. You most likey have a dirty flame sensor. Under the burners you should find a "single" wire going to a connector. This will be to the far left or right. Just opposite of a "two" white wires going to the hot surface igniter. Remove the 1/4 inch screw closet to the single wire under the burner. carefully pull out the flame sensor. Clean it with a small piece of sandpaper. Re install it. This should fix your furnace. KEEP IN MIND Goodman GMP models are noted for defective heatexchangers. Pull out the blower assembly and turn it over. If small rings about the size of a dime falls out.... this furnace is unsafe and should replaced!
