Carrier 48JZ024040300 Ignition Control Board
The main ignition control board checks out the gas valve, the ignition sequence and all the flame sensing devices. It has been a very important board that is usually a part of the main control board for the sake of being more efficient.
Major signs the ignition board should be replaced
- The ignition system is unwilling to activate then the thermostat send a signal
- Every other thing within the furnace checked out to be good
- Initial communication from the primary thermostat never makes contact with the main control board
