I have a goodman/janitrol furnace model number gmp075-3. when the t-stat calls for heat the fan turns on and the status light flashes 5 times, which is false flame sensed. i have replace the ignighter and jumped all the the sensors and it still flashes 5 times. any suggestions?
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.
IS it the inducer motor coming on right away, or the blower, becuase if it is the blower than you are out on a high limit, depend on the model goodman puts to manual resets on each side of the blower motor. please give more info
I have Goodman GMP075-3 it runs one cycle gas shuts off and house fan remains running. I shut off by opening door and releasing door switch. leave off or twenty minutes close and turn on thermostat and it runs another cycle. look under panel and the led flashes 5 times (false flame sensed) or it starts again, but usually flashes unless left off for same time period.

Some those codes represent other things as well,,,when u say fan do you mean the combustion fan if so then its not making the switch there is round switch on the side with rubber hose to it,,jumper it if runs try cleaning out the hole on the combustion fan motor,,,if not need to replace the switch assuming the fan is pulling enough vacum,,,not much info to go on,,,need more to diagnose 100% good luck.

Same problem. Any luck? Guess I'm going to replace the control board and see what happens. Changed T-stat and had no luck there. Fans just keep running and running... Oh, SOMETIMES it will ignite but very random.
I'm having this problem aswell. First day just the inducer motor would run. I come back today both fans blowing. I stick a volt meter on the ignitor nothing. I close the main blower door it fires up just fine!!!! I pull the main blower door to make sure I got a good seal. Replace it and its back to 5 blinks???? HELP!!!
