Haier CPN10XC9 Ignition Control Board
The ignition control board is a safety device that keeps an eye on gas intake, the ignition ignitor and all the flame sensing devices. It has been a very important electronic circuit board that, in most cases, has become a major component of the main board instead of its own individual board.
General warnings of a failing main ignition board
- Everything else in the system is inspected and turns out to be a-OK
- Heating and cooling system is unable to kick in when called upon
- The on-signal from the main thermostat does not show up at the main control board
