Lennox 13ACX-048 Ignition Control Board
The main reason to have an ignition control board is that it checks gas intake, the ignition timing and all the flame sensing devices. It has been a very important electronic circuit board that some manufacturers have decided to blend to be a major component of the main board for the sake of being more efficient.
Hints of a weak ignition board
- The main ignition cycle declines to fire up then the thermostat send a signal
- The on-signal from the primary thermostat does not reach the main board
- Every other device connected to the system is researched and comes to be just fine
