SOURCE: goodman gmp075-3 led blinks 5 times

I Also have the same and other problems with my furnace model # GDS80703AXBB. First the LED kept blinking 4 times and I too jumped the primary limit, that didn't kelp. After several attemps I moved the wires going to the circut board and everything starting working again. After a week It stopped working again, so I pulled the plug out of the circut board checked all wires for for a bad connection plugged it back in. Now the LED blinks 6 times again I move the wires. Then the LED blinks 3 times. Then the transformer burns out. I have burned out 2 transformers and I have ordered a new circut board.

Hi,
I don't have the same system, but on mine when I replace anything, I have to reset the system by killing power to it for a few minutes.
I hope yours is the same,

My Goodman furnance blowing cold air.I have 4 LED flashing lights


Reset the power to see if the furnace tries to light. If it tries & fails, it is an ignition issue ie hot surface igniter, dirty flame sensor. If the LED's still are lit up, it is most likely a limit that is open.

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.

Burners not firing & LED flashing 4 times


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.
A typical limit looks like this: themobilian_1380.jpgConsult your furnace schematic to determine how many of these puppy's are wired in and around the furnace. Make sure they all have continuity. Have the power OFF before you reset the limit. Ouch!

Somewhere in your furnace all of these flashes have a chart you can consult usually located on the backside of the blower cover.

Suddenly not working im not sure if there even is a pilot to be lit


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.

1 Answer

6 blinks


sounds to me like i wish i could find out if this is new install or if the electric has been changed recently,,,sounds like reversed polarity on the plug,,,which means the white and black wires need to be swapped. If there has not been change recently than u need to see the other post i made on goodman about the combustion fan motors and there types and fixes. But almost certain that is reversed polarity. good luck
