International Comfort Products PHF042K000A Ignition Control Board
An ignition control board oversees the gas valve, the igniter and a few other devices. It has always been a vital device that is usually a major component of the main board for the sake of being more efficient.
Easy warnings of an unhealthy ignition control board
- Ignition system does not kick in when called upon
- The initial signal from the remote thermostat never reaches the main board
- Everything else within the heating and AC system is inspected and turns out to be OK
