Carrier 58MXA100F14120 Ignition Control Board
The main ignition control board keeps an eye on the natural gas, the ignition sequence and the flame sensing circuits. It has been a very important circuit board that is usually a part of the main control board instead of its own individual board.
Subtle cues of a poorly performing main ignition board
- Every other problem in the system is looked at and turns out to be swell
- The electrical signal from the home thermostat does not reach the main board
- Ignition sequence will not initiate even when called upon
