Nordyne MS3BA048KA Control Board
Your system definitely will not function unless this important circuit board is installed as it should be according to the manufacturer. The control board is made to direct the gas valve, the igniter, all the sensors as well as the air circulator all at once. You must be careful upon picking a replacement board because of the diversity of models and types. The board you select should be compatible with both the brand and specific model of furnace or air handler you have.
Signs your primary control board will not last the year
- There seems to be a fault code shown directly somewhere on the board
- The board has to be turned off and back on a lot for everything to run again
- The furnace or AC is unable to work correctly
