International Comfort Products N9MP2100F14A2 Control Board
Heating and cooling systems will not even operate whatsoever without the main control board in connected and operational. The control board is constructed to control the gas valve, the igniter, the flame sensor as well as the blower all at once. The control board you choose is supposed to have a part number that matches both the make and model of the unit in question. Be very careful when you choose a replacement due to the vast differences in brands, models and types of systems.
Main clues your main board will need replacing
- The system has to be powered down and back up repeatedly for the furnace or AC to kick on
- When turned on, there is a fault code indicated directly on the front of the control board
- The whole unit ceases to start properly
