International Comfort Products PGMD48G1356 Ignition Control Board
The main ignition control board governs the natural gas, the ignition timing and some more sensing equipment. It has always been a vital circuit board that has now become a vital part of the main control board instead of a separate board.
What symptoms are present when the main ignition board is almost dead?
- Everything else in the system is inspected and seems to be acceptable
- HVAC ignition system fails to initiate even when the thermostat kicks it on
- The on-signal from the remote thermostat never gets to the main board
