Samsung AVMWH040CA0 Control Board
The HVAC system will be unable to activate lest the circuit board is accurately installed and configured. The control board is created to oversee everything including the gas valve, the ignition igniter, the flame sensor and the blower all in one unit. The chosen circuit board will need to pair with the part number from both the make and model of air handler system you have. You must be sure when you are deciding on a replacement because of the diversity of systems.
Major indications of a poorly working Samsung control board
- The whole unit is unable to run at all
- System has a strange code suddenly appearing somewhere on the circuit board
- Power to the circuit board has to be turned off and back on many times a day for it to work
