International Comfort Products NBF075B12A1 Control Board
Most systems will not function unless this important circuit board is correctly installed. The control board is constructed to oversee the gas valve, the ignition igniter, most sensors as well as the blower all in one unit. The selected board should match the model number with both the brand and specific model of the system you have installed. Be absolutely sure upon choosing a board as a replacement due to variances between heating and cooling systems.
Warnings of an inadequate control board
- AC or heating system is unable to function properly
- The HVAC system needs to be reset all the time for everything to run again
- System has a type of code being displayed on the circuit board
