Goodman GCH91155DX Ignition Control Board
The purpose of the ignition control board is that it oversees gas flow, the ignition sequence and some other sensors. It is an important safety feature that, over the years, has merged to become a part of the main control board for the sake of being more efficient.
Major clues of a bad main ignition board
- Any other device attached to the system checked out to be okay
- The primary ignition sequence is unwilling to activate when it receives a proper signal
- Signal from main thermostat never does reach the main control board
