Lennox CBX32MV-036 Ignition Control Board
The purpose of the ignition control board is that it has control over the gas valve, the ignition ignitor and some other sensors. It has always been a vital safety device that some companies have moved to be a vital part of the main control board instead of its own individual board.
Key indicators that my chief ignition control board is dying?
- The main ignition cycle does not start when it receives a proper signal
- Every other thing within the system is inspected and turns out to be fine
- The initial signal from the home thermostat does not turn up at the main control board
