Goodman GDH81155CX Ignition Control Board
The main ignition control board keeps an eye on the main gas intake valve, the ignition sequence and other safety devices built into the system. The ignition control board was always an important safety feature that, in most cases, has become a major component of the main board instead of its own individual board.
Important signs your Goodman ignition control board has to be replaced
- Every other thing within the system is explored and ends up being okay
- The on-signal from the main thermostat gets lost before it makes it to the Goodman control board
- HVAC ignition cycle fails to begin no matter what
