Using a multimeter, check the continuity of the pressure. Take the cover off the burner compartment of the furnace. This is probably because the gas valve closed to slowly or some other reason that.
This Time The Hsi Starts Glowing And Maybe A Second Later The Gas Solenoid/Valve Opens And Ignites The Furnace.
Condensate pipes may need to be replaced if they are cracked in your goodman furnace. Those valve issues were resolved around 2013 by the manufacturer they added a small spacer on the shaft to prevent it from over driving. I have a 20 yr old goodman furnace that gets to ignition stage but does not open the gas valve.

You can fix the problem by cleaning or replacing the ignition sensor, ensuring the gas valve is open and undamaged, and your gas tank is full.
Using A Multimeter, Check The Continuity Of The Pressure.
You should find a rating plate with the model of the furnace. If it’s still not working, you’ll need to check the breaker box to make sure the circuit breaker is turned off. Everything has proper voltage except for the purple wire running from the board wire cluster through all the rollout sensors and up the gas valve.
