Question about Heating & Cooling
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.

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??

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!!

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)
