Lennox XC21-036 Ignition Control Board
The ignition control board is a safety device that checks out the main gas intake valve, the ignition sequence and the flame sensing circuits. It has always been a vital board that some manufacturers have decided to blend to be a piece of the main circuit board for safety reasons.
Important hints your ignition control board is in need of replacing
- HVAC ignition system declines to initiate when it is supposed to
- Communication from the main thermostat never makes contact with the main board
- Every other problem throughout the system is inspected and seems to be flawless
