Source-linkedVerify source — Reddit post

About two-year-old Goodman GM9S921205DN furnace (installed April 2024) would light then drop flame after 20–60 seconds and lock out with code EE0. Multiple contractors replaced the pressure switch, gas valve, and control board before a universal pressure switch finally fixed it; owner notes Goodman pressure switches for certain models are defective out of the box with a pending service bulletin.
