International Comfort Products H9MPD125L20B1 Control Board
The control board is created to operate everything including the gas valve, the ignition igniter, the flame sensor and the blower all at once. Most systems will not be able to function lest the main control board is in connected and operational. Any control board you choose is supposed to have a part number that matches both the brand and specific model of the unit in question. You should always be careful when you are choosing a replacement board due to variances between models and types.
Important clues of a faulty main board
- There seems to be numbered code revealed on the control board
- AC or heating system is unwilling to function properly
- The system has to be turned off and back on rather frequently in order to continue running
