DeLonghi PAC 400 Ignition Control Board
The main ignition control board manages the gas valve, the igniter and other important devices. The ignition control board was always an important safety device that has now become a major component of the main board instead of having two separate boards.
Red flags the ignition board will soon need to be replaced
- Heating and cooling system will not kick in when called upon
- Every other problem in the HVAC system is inspected and seems to be swell
- Signal from main thermostat never does reach the DeLonghi control board
