Samsung AVMHC105EA0 Control Board
The control board is made to regulate the gas valve, the ignition igniter, the flame sensor as well as the air circulator all together. Most systems will not activate lest the circuit board is installed. Be very careful when you choose a replacement due to differences in brand and air handler types. The board you choose will have a matching part number that will fit in both the brand and model of furnace or air handler you have.
Some warnings your control board needs a replacement ASAP
- The furnace or AC does not operate correctly
- The system board has to be powered down and back up frequently for the system to continue working
- There seems to be some sort of code displayed somewhere on the circuit board
