Samsung AVMWH020EA0 Control Board
The control board is constructed to operate everything including the gas valve, the ignition igniter, all the various sensors and the blower all together. Your air handler will be unable to run without the main control board properly connected to the unit. Be absolutely sure upon choosing a board as a replacement because of the many variances of heating and cooling systems. The chosen circuit board will have a matching part number that will fit in both the make and model of the unit in question.
Indications of a bad control board
- Heat or AC unit refuses to run whatsoever
- The system board needs to be reset a lot for everything to run again
- There seems to be an error code being displayed on the front of the control board
