Carrier 48JZ048090300 Ignition Control Board
The main reason to have an ignition control board is that it checks out gas intake, the ignition sequence and other safety devices built into the system. It has always been a vital safety device that is usually a major component of the main board for the sake of being more efficient.
Cues of a defective ignition board
- The electrical signal from the main thermostat never gets to the control board
- The ignition system will not start even when the thermostat kicks it on
- Any other potential problem within the heating and AC system is inspected and turns out to be in good health
