What does 8 mean?

When you see Goodman error code 8, it means your system's ignitor isn't working properly. The ignitor is responsible for creating a spark to light the burner in gas furnaces. This error is common in Goodman's NCB, NPE, and GPC series. It could be due to a faulty ignitor, a problem with the control board, or a wiring issue. Don't worry, your system is still safe to run in fan mode for cooling.
