Carrier 58MXA140 Ignition Control Board
The ignition control board is a safety device that has control over the gas valve, the igniter and all the flame sensing devices. It has been a very important electronic safety board that is now usually a part of the main control board instead of a separate board.
Do you know if your Carrier ignition control board is about to go out?
- Initial communication from the main thermostat never gets to the main control board
- HVAC ignition cycle is unwilling to kick in even when called upon
- Any other device in the system is explored and ends up being a-OK
