Question about Goodman GMS90703BXA Heater
Sounds like the flame is either not traveling to the flame sensor or the flame sensor is dirty or bad. Look to the far left of the burner box for a probe near a burner. Lightly scrape and debris from the probe. The probe will have only one wire going to it. Do not touch the igniter or it will break.

This sounds like a pressure switch problem... turn off..locate pressure switches...take off connoctions and shake them upside down (this is to get condensation out of them) once you know they are dry replace them turn on and start. It could also be your intake air pipe is cloged or the exhaus air is blocked
