International Comfort Products PGMD36G0604 Ignition Control Board
The main reason to have an ignition control board is that it manages gas flow, the ignition ignitor and some more sensing equipment. The ignition control board was always an important electronic safety board that, in most cases, has become a part of the main control board for the sake of being more efficient.
Key clues of a deteriorating major ignition board
- HVAC ignition cycle declines to launch at all
- The initial signal from the remote thermostat never makes contact with the main control board
- Every other device within the heating and AC system is inspected and turns out to be OK
