Samsung AVMWH020CA0 Control Board
The Samsung AVMWH020CA0 control board is constructed to command the gas valve, the igniter, the flame sensor as well as the air circulator all together. HVAC systems will not operate lest this board is in place and connected. Be very careful when you decide to replace your control board due to differences in brand and air handler types. The selected board should match both the make and model of the unit you have installed.
Key symptoms of a failing control board
- The board needs to be reset quite frequently for the thermostat to kick in
- The heating and cooling system is unwilling to work well
- There seems to be some sort of code indicated directly somewhere on the circuit board
