Delonghi C100 Control Board
The HVAC system will be unable to be able to function without the main control board installed as it should be according to the manufacturer. The control board is constructed to command the gas valve, the igniter, all the sensors as well as the air circulator all at once. The selected board will need to be a match with your existing board and be compatible with the brand and the model of the system you have installed. You must be careful when you choose a replacement because of the many variances of brand and air handler types.
Major indications of a bad main circuit board
- There may be a fault code shown directly somewhere on the board
- System does not start correctly
- The whole system has to be reset all the time in order to run
