Friedrich MW30C3G Control Board
The control board is constructed to command everything including the gas valve, the ignition igniter, most sensors as well as the blower all together. Your air handler will be unable to operate lest the main control board is hooked up and is correctly configured. It is imperative that you select wisely when you are choosing a replacement board because of the many variances of heating and cooling systems. The control board picked should have part numbers that match both the brand and specific model of the system you have installed.
Major indications your primary control board is in dire need of a replacement
- When turned on, there is a certain error code instantly appearing on the front of the control board
- The furnace or AC refuses to run well
- Power to the control board has to be powered down and back up many times a day for the heating or cooling to kick in
