Whynter ARC-142BX Ignition Control Board
The ignition control board is a safety device that checks gas flow, the ignition ignitor and some more sensing equipment. It is an important safety feature that some manufacturers have decided to blend to be a standard part of the main board for enhanced safety.
Easy warnings the ignition board has very little life left
- Signal from main thermostat never does reach the control board
- HVAC ignition cycle declines to launch when it receives a proper signal
- Everything else in the system is inspected and seems to be a-OK
