Samsung AVMHC105CA0 Control Board
HVAC systems will not activate without the control board properly connected to the unit. The control board is created to command everything including the gas valve, the ignition igniter, all the various sensors as well as the air circulator all at once. Be very careful while selecting a replacement because of the diversity of particular brands and their models. The chosen circuit board should match both the brand and specific model of air handler system you have.
Important clues of a faulty control board
- Could be an a type of code indicated directly on the control board
- The HVAC system has to be reset many times a day for everything to run again
- The furnace or AC cannot start well
