Carrier 38HDR060 Ignition Control Board
An ignition control board controls the gas valve, the ignition ignitor and some other sensors. It has always been a vital electronic circuit board that some manufacturers have decided to blend to be a part of the main control board for the sake of being more efficient.
Major clues of a weakening ignition board
- Ignition cycle fails to initiate no matter what
- Every other potential issue throughout the system checks out fine
- Signal from home thermostat never reaches the main control board
