Goodman furnace GMP075-3 The thermostat was in the off position over night and sometime during the night, the induced blower and blower motor came on. The trouble light on board blinks 5 times. I checked...


Need your model # to check the codes but, this coming back on after turning the t-stat off is rare. You may have been in a lockout and the furnace re-started. Some furnaces try to start three times , then lock out. Time out, then re-start. The codes should be on your furnace blower door. Write back with this info and i could help.

Goodman furnace fault light blinks 3 times it kicks on but does not blow heat?


Hi, what you have to do is where you see this light flashing, there is a circuit board. Remove the panel. If everything goes black, you have a door switch on the perimeter that you can tape down to restore power to the furnace. On the panel, you will find a error code sheet glued on it telling you what the flashes mean. 3 flashes may say you have an open pressure switch, or 4 may say the inducer motors off or something else. It will almost troubleshoot itself. Find out what the 3 flashes mean and if you cant figure out what to do, contact me and I will walk you through it. It sounds like you have a dirty flame sensor, or an intermittent problem in the ignitor module. Check it out as it will tell you.
Sincerely,

Goodman GDS80904BNA LED Blinks 3 Times


had similar problems with same furnace. I think the 3 blinks is high limit event. either way with the power off to the furnace remove the board from the 4 clips holding it on one at a time then turn it over and look at it you will be able to tell if the board is bad because it will appear scortched and the resin will be bubbled up where it went bad. replace board and you will be fine. went through 2 in 2 years all of a sudden they are being made by a different company from the original and the 1st replacement. now all is fine. Take a good picture of the board close up so you can reconnect all the wires properly. Friend of mine got it from a wholesaler for $55.00

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.

Glow light blinks once


One thing to try is to check the voltage coming to the furnace to see if it is correct. They do have separate furnaces for California because of the NOX compliable laws but the boards according to my vendor are all the same. Look on the new board to see if you see any of these numbers # PCBBF112S or 01030F00005S. If you do have one of these numbers it is the correct board. If not change the board or if voltage is wrong get that corrected and you should be fine

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.

the pressure switch is closed before the draft motor closes it.the board is telling you that this is not right.pull the wire(either) off of the pressure switch to see if furnace tries to light.if it does,you should replace the pressure switch.
