Samsung MH052FNCA Control Board
The Samsung MH052FNCA control board is constructed to command everything including the gas valve, the igniter, most sensors as well as the air circulator all in one unit. Your system definitely will not operate whatsoever unless this important circuit board is installed. It is imperative that you select wisely while searching to pick up a replacement control board due to differences in heating and cooling systems. The proper control board should match the model number with both the brand and specific model of your particular system.
Signs your primary control board will eventually need to be replaced
- The system board has to be powered down and back up quite often for it to kick in
- There may be some sort of error code indicated on the control board
- The unit does not function period
