Carrier 48JZ Ignition Control Board
The main ignition control board oversees the natural gas, the ignition sequence and other important devices. The ignition control board was always an important electronic circuit board that has now become a standard part of the main board instead of a separate board.
Warnings of a failing main ignition board
- Ignition sequence declines to launch even when the thermostat kicks it on
- Every other device within the heating and AC system is researched and comes to be acceptable
- The electrical signal from the primary thermostat never makes it to the main control board
