Friedrich MW09Y3H Control Board
The control board is created to operate everything including the gas valve, the ignition igniter, all the sensors as well as the air circulator all at once. Most systems will not operate whatsoever lest the circuit board is correctly installed. The board that you will choose will need to be a match with your existing board and be compatible with the brand and the model of your particular system. You must be sure upon picking a replacement board due to variances between systems.
Some warnings of an ineffective main circuit board
- There may be some sort of code lit up on the control board
- The unit is not able to work properly
- The system has to be turned off and back on a lot for it to run
