Samsung AVMWC070EA0 Control Board
Your system definitely will not operate unless this important circuit board is in place and connected. The control board is made to command the gas valve, the igniter, most sensors and the blower all at once. You must be careful while choosing a new control board due to differences in particular brands and their models. The board you choose should match the model number with both the make and model of air handler system you have.
Cues of a laboring main board
- System has a strange code shown on the circuit board
- Your HVAC unit declines to initialize well
- The system has to be powered down and back up a lot for it to kick in
