Question about Goodman GMS90703BXA Heater
I have a 15 year old Goodman GMP075-3. The unit will not remain on more than 10 seconds. The igniter is new, the flame sensor has been cleaned with steel wool, I checked and re-seeded all wire connections for corrosion, the gas is igniting on all 3 burners. I still get one blink on circuit board and it still won't remain on more than 10 seconds.
I turn on the heat on the thermostat and the unit won't stay on. The gas would ignite but the flame would immediately go out. That will continue throughout the day. Sometimes it will heat up the house, but a majority of the time it don't.

Replace the thermostat control sounds like the control contacts are not holding since you cleaned the bulb and the igniter is working the only other issue is the thermal buld being bad, shut it off heat the bulb for three minuts then quickly turn it back on and see if it stays on longer if it does the bulb is the problem.

since your getting ignition it sounds like it is shutting off due to airflow
you may want to drop the fan and check the coils above it
and the coils in the pelum with out proer air flow these units shut down at 180 degrees will cycle when cooled again
since your getting ignition your inducer seems to be fine
