Carrier 38TXA030 Ignition Control Board
Another safety feature is the ignition control board, which governs the main gas intake valve, the ignition sequence and some other sensors. The ignition control board was always an important electronic circuit board that, in most cases, has become a vital part of the main control board instead of a separate board.
Major signs to watch for in a bad ignition control board
- The primary ignition sequence is unable to fire up when called upon
- Every other potential issue in the HVAC system checks out in fine condition
- Communication from the remote thermostat does not reach the control board
