SOURCE: goodman model 135-5 furnace fan and induce motor
Is there a thermal Fan/Limit switch in this furnace? If so you may need to tweak the low range setting so it can turn off the blower.

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!!

it sounds like the low temp limit switch, the one that cools the furnace down with the burner off and the thermostat open, when it cools to a point the fan stops, the other switch in burner area turns burner off/on, hope this helps
SOURCE: Our furnace keeps shutting down soon after burner
Sometimes a "Flame Sensor" gets carboned up and does not detect that the furnace has ignited, so it shuts down the fuel source. Might try cleaning that if so equipped.

I would first try to power up the inducer motor by itself. If this works without any issue than the next step is to look at the circuit board. You will need a multimeter. Set it to 120V AC and test the leads on the circuit board that the inducer motor attach to. Turn the system on and see if you get a reading on the meter, if so, then you know the motor is getting power. I would then check the legend of your furnace with the led pattern. You mention it is steady, look up what the steady light means. It may point to a control board error, in that case you will need to replace the board.
