Lennox G43UF-36C-090H Ignition Control Board
The purpose of the ignition control board is that it may control gas intake, the ignition timing and the flame sensing circuits. The ignition control board was always an important electronic safety board that is now usually a major component of the main board for safety reasons.
Signals the ignition board should be replaced
- Ignition sequence is unable to fire up when it receives a proper signal
- Every other problem within the furnace is inspected and turns out to be in fine condition
- The on-signal from the thermostat never gets to the Lennox control board
