Nordyne M1BB086 Control Board
Most systems will not function unless this important circuit board is installed. The control board is designed to operate the gas valve, the ignition igniter, all the sensors as well as the blower all in one unit. Any control board you choose will need to be a match with your existing board and be compatible with both the brand and specific model of the unit in question. You should always be careful when you choose a control board due to variances between systems.
Cues of a weak main circuit board
- The AC or furnace refuses to initialize at all
- Power to the control board has to be turned off and back on all the time for the system to operate once again
- There is a certain error code appearing somewhere on the circuit board
