I am a home owner and have a Goodman GMP075-3 (Serial # 9901611013) with a strange intermittent problem. The call for heat is made from the thermostat, the ID motor starts, after a short period of time the burners fire up. Now intermittently, it sounds like the burners are struggling to stay lit (sounds stupid but sort of a whoosh, whoosh, whoosh sound). After a few seconds the gas valve clicks and shuts off the burners. With the ID fan still running this process will repeat until the burners stay lit, usually only one more time. The LED on the controller board has never flashed, just stays solid red.
I have called a professional who has been out three times. First time he replaced the flame sensor, second time he replaced the pressure switch. The last time he came out he cleaned the burners and the entire unit. None of this helped.
Does anyone have any suggestions?
Thanks,
Ed
