I see no answer was put here, but I am having same problem, Goodman furnace. LED flashed 3 times. No heat. Please let me know what you think.
Manual says possible causes are
1. pressure switch hose blocked, pinched or connected impropertly
2. blocked flue and or inlet air pipe blocked drain system or weak induced raft blower.
3. incorrect pressure switch setpoint or malfunctioning switch contacts
4. loose or impropertly connected wiring
This is just a 2 year old unit, and was working fine last winter.
Let me know
