Haier HPN12XCM Ignition Control Board
The main reason to have an ignition control board is that it checks out the main gas intake valve, the ignition timing and all the flame sensing devices. It has always been a vital device that, in most cases, has become a piece of the main circuit board for safety reasons.
Subtle cues of a defective chief ignition control board
- The primary ignition sequence declines to initiate no matter what
- Initial communication from the main thermostat does not show up at the Haier control board
- Every other device in the heating and cooling system is inspected and seems to be swell
