Samsung AVMDH070EA0 Control Board
Your air handler will be unable to run without the board accurately installed and configured. The control board is constructed to oversee everything including the gas valve, the igniter, most sensors as well as the air circulator all in one unit. It is of utmost importance when you are choosing a replacement board due to the vast differences in certain brands. A replacement board will have a matching part number that will fit in both the brand and model of your particular system.
What are the clues to watch out for to know my HVAC circuit board is about to go out?
- Everything has to be powered down and back up habitually for it to work
- The entire system ceases to function at all
- There may be some sort of code appearing on the board
