Working on a 2 year old GMS90703BXA, condensate will not drain while its running. Shut it off it'll drain. Nothing is plugged.
Do you have pictures you could post?
If any one shortened the plastic pipes that stick down into the trap, it will change the characteristics of the trap.
The top of the trap MUST be lower than 2" below the hole in the side of the furnace for the drain to work properly.
Does it drain with the top access pannel removed? If it does, you could have a combustion air supply problem.
Measure the static pressure at the collection box cover drain with a mannometer to see what the inducer is doing.
For MOST brands the inducer will pull 2" wc and therefore the trap must be lower than 2" below the lowest condensing tap....
Ignore those who belittle Goodman, they are jellous that they cannot compete with price and generaly repair the ones that have been improperly installed in the first place...

Those who dance, appear insane to those who do not hear the music.
Those who believe, appear ignorant to those who do not know God.
