International Comfort Products C9MPT125L20A1 Control Board
HVAC systems will not operate whatsoever unless this important circuit board is accurately installed and configured. The control board is created to control the gas valve, the ignition igniter, most sensors and the blower all at once. You must be sure while picking a new replacement board due to the vast differences in brands, models and types of systems. The board that you will choose should match both the brand and specific model of air handler system you have.
Indications your primary control board should need replacing
- The whole system has to be turned off and back on frequently for everything to run again
- The HVAC system does not operate at all
- There may be a numbered error code lit up on the board
