Carrier 58MXA040 Ignition Control Board
The main reason to have an ignition control board is that it controls gas flow, the igniter and other safety devices built into the system. It has always been a vital circuit board that is usually a standard part of the main board for enhanced safety.
What are the indications that my ignition board is almost going bad?
- HVAC ignition system refuses to start when it receives a proper signal
- Initial communication from the primary thermostat does not get to the main control board
- Everything else within the heating and AC system is looked at and turns out to be flawless
