Carrier 25HPA530H0030010 Ignition Control Board
The ignition control board is a safety device that checks out the main gas intake valve, the ignition sequence and other safety devices built into the system. It has always been a vital electronic circuit board that is usually a piece of the main circuit board instead of having two separate boards.
What to see if the ignition board is crapping out?
- Every other potential issue within the heating and AC system checks out in good health
- Ignition sequence declines to initiate at all
- Initial communication from the main thermostat never does reach the main control board
