Donald for Model Number LRBC20512WW How can I run diagnostic mode? All temperatures are fine in frig/freezer, and the display board is not working. If you unplug it, it will work for a time then only the right side shows, and then only 456 on display will light up, but both freezer/frig work.

The display board should receive constant voltage and if it does receive constant voltage during a state of failure, then the display board [6871JB2047A] is bad.
