Lennox CBX32M-024 Ignition Control Board
An ignition control board manages the natural gas, the ignition timing and all the flame sensing devices. It has been a very important electronic circuit board that some companies have moved to be a part of the main control board for safety reasons.
Simple indications of a weak Lennox ignition control board
- The main ignition cycle is unable to fire up when it receives a proper signal
- Every other device throughout the system is looked at and turns out to be in good condition
- Initial communication from the main thermostat does not reach the main control board
