If the burners ignite and then turn off it looks likemthe flame sensor is the problem. On the opposite side of the igniter in the burners will be a metal rod, this rod needs to be cleaned with a steel wool pad. Once it's clean turn Furnace back on.

SOURCE: No heat, trouble shooting light has continious flash.

There is a vacuum sensor on most units tied from the exhaust gas fan to the sensor. Does the unit try to start? If the unit's exhaust fails to pull the switch it will turn off after about 30-45 sec after starting. "IT" thinks it's not exhausting and stops to keep from overheating. Do you have this exhaust fan and rubber hose to sensor? Can you see if that fan is turning on start?

Ok, you either have a inducer fan issue or a pressure switch issue or a plugged vent pipe. The inducer turns on to establish a draft for the exhaust. If it is not working you will get this error code. If the pressure switch does not sense pressure caused by the inducer, it will give this code. If either the intake pipe or exhaust pipe is blocked (even y just a little) it will give you the same error code. If the condensate hose or receptical is plugged, again it will give you this error code. Good Luck!

I have a goodman GMP075-3 that won't turn on. I think it is the pressure switch since I do not have a vent blockage. What is a venter and where can I find it??

SOURCE: Burner ignites and goes out (Goodman Gas-fired furnace)

Hi,
The problem you have is water in the exhaust pipe.
Check to see if the pipe has sagged anywhere or if there is a trap in the line.
If you hear gurgling then it is definetly water....
Some times can be hard to find, even a pipe 1/4 full will cause problems. They are very sensitive to flue problems.
Make sure that the flue pipe either runs back to the furnace or out to the outside, a continuos slope either way witha high spot in the middle.
Also check the bottom drain of the blower if it has one, have had them plug and trap water also..

I hope that this will help you to solve your problem!

Thanks for using Fixya!!

SOURCE: Goodman furnace burner ignites then shuts off in about 10 seconds

if you have replaced the flame sensor and it will not stay lit, the draft safety switch may be opening. It works on positive and negative pressure created by the inducer fan motor.You may have a restriction in your heat exchanger or if is a high efficiency furnace, it may not have the drain tube installed properly with a trap. The trap works just like the trap under your sink and if water isnt in the trap, the pressures can be effected enough to open the draft switch(some call it an air pressure switch)

Goodman gmp100-3 furnace The furnace will not start when I turn power on. It will hum but no click. The status light is solid red. Could the ignitor be bad? And what color should it be?


You should hear the ignitor pop. If you don't hear that pop sound, then the igniter is bad. They are easy to change, just make sure you turn the gas off and the pit-cock into the appliance and take a photo of exactly where the igniter tip is oriented so you can put the new one in the same spacing to have it ignite properly. The status light should be green when the furnace is 'On.'

My goodman furnace 80703 fan comes on ignitor glows burner starts , cuts off in 10 secs,furnace starts cycle again. home no heat


I am not a furnace tech but, there are several inputs to a gas valve. There must be an 1) electrical/mechanical indication that there is a draft fan running (to move potentially explosive gas so it doesn't accumulate), 2) adequate gas pressure to the valve, 3) the thermostat must be calling for heat 4) and electrical indication that there is an ignition source. In your scenario, you have the source of ignition, the gas valve is picking up the burner but the gas valve believes there is something missing so it shuts off the gas to the burner. In this case, I suppose you might not have enough gas pressure (is another gas appliance running or is the line to the furnace too small?), a thermocouple probably isn't the problem since the burner wouldn't pick up if the gas valve didn't believe the ignition source wasn't good enough. You could have a plugged chimney or exhaust pipe if it is direct vented since there is also a pressure switch that detects whether there is enough draft once the burner picks up. Really should call a furnace person especially if you don't have a carbon monoxide detector that you trust. If you think you are capable of continuing, you could jumper the various inputs the the gas valve one by one until the burner picks up and stays picked up. Whichever terminals you jumper that accomplish this, is the culprit. Look at the schematic on the side cover to the furnace for this information. Hope this helps...

Furnace ignition controls will attempt to light the furnace 3 times with several minutes delay between each attempt. If it fails to light or the ignition module fails to detect it lit after the 3 tries, the module will lock out and require a "Hard Reset" to try again. It is a common feature in nearly all newer furnaces intended to let you know you have a serious problem. You should call a service technician for this because there are a number of things that may be causing this flame failure. Please grade my answer on how much I have helped you. Thank you for the opportunity. Roger

I have a downdraft Goodman furnace. On only some occasions the blower will start, then after a few seconds I will see the igniter light up, but then I do not get the rush of gas and lighting of the...


It sounds like you got a tough one there.When you say the blower starts up and then the igniter comes on are you refering to induced draft motor or main blower. The proper sequence is for the thermostat to call for heat at which point the induced draft motor should come on and run for 30-45 seconds,then the igniter should heat up for a few seconds then gas valve should open and main burner should light. After limit switch reaches set point for fan on ,blower should come on till after heat has reached thermostat setting then burner should go out, and blower run until fan off setting is reached on limit switch. If your furnace is not following this sequence and then not always doing the same thing in the same order,I would recommend that you change out board again. I have had several problems similar to this with Goodman units and all but one time installing new board solved it. That time I did everything I knew to do and talked to factory service techs repeatedly and finally installed new furnace. As far as your question about insulation,. As long as it is fire proof I can't see where it would hurt anything. Sorry I'm not more help. Good luck and thanks.
