Friedrich MW12C1H Control Board
HVAC systems will not operate whatsoever lest this board is in its proper place and configured for your unit. The Friedrich MW12C1H control board is made to command everything including the gas valve, the igniter, all the sensors as well as the blower all in one unit. You must be sure when choosing a control board due to so many small differences in HVAC systems. A matching board will have a matching part number that will fit in both the make and model of the unit you have installed.
Key clues of a failing main circuit board
- There is flashing code randomly appearing on the board
- The whole system has to be powered down and back up quite often for the system to operate once again
- Your system does not work well
