Lennox HP13-036 Ignition Control Board
The purpose of the ignition control board is that it has control over the natural gas, the igniter and all the flame sensing devices. It is an important device that some manufacturers have decided to blend to be a piece of the main circuit board for the sake of being more efficient.
Indications your ignition control board has very little life left
- Every other device in the heating and cooling system is inspected and seems to be fine
- Ignition sequence will not commence even though it is supposed to
- The electrical signal from the thermostat never turns up at the main board
