Samsung AVMWH070EA0 Control Board
Your furnace or AC will not be able to function unless the control board is in its proper place and configured for your unit. The Samsung AVMWH070EA0 control board is made to regulate everything including the gas valve, the igniter, all the various sensors and the blower all at once. The selected board must have a matching part number consistent with both the brand and model of the system you have installed. Be absolutely sure while searching to pick up a replacement control board due to variances between systems.
Major clues to watch for in a failing main board
- Air conditioner or furnace cannot start well
- There seems to be a fault code displayed somewhere on the circuit board
- The board has to be powered down and back up quite often for everything to run again
