If you have replaced the HV control board on your Maytag MFI2067AES refrigerator and programmed the code from your refrigerator, but the code is not being saved, there could be a few possible causes:
- Wrong board: It's possible that you may have installed the wrong control board for your refrigerator model. Make sure to double-check the part number and compatibility before installing a new control board.
- Improper programming: Make sure that you are properly programming the control board with the correct code. Follow the manufacturer's instructions carefully and ensure that you are entering the code correctly.
- Control board issue: It's possible that the control board itself may be defective and is unable to save the code. Try resetting the control board to factory defaults and reprogramming it with the correct code. If the issue persists, you may need to replace the control board again.
- Other issues: There could be other issues with your refrigerator that are preventing the code from being saved, such as a faulty user interface or a problem with the door switch. You may need to perform further diagnosis or seek the help of a qualified repair technician to identify and fix the issue.
