I have the 31-9227.pdf service document, and followed the instructions about pressing the three buttons for getting into service diagnostic mode, however the display is different than the pictures (low res screen, no prompt for "enter service mode?"
I selected the 00 47 test for the refrigerator fan (which wasn't running), but nothing happened.
According to the doc, the fan should run at 75% and the RPMs should be on the display, but neither happened.
Is there a button I need to press to actually start the test, or does "nothing happened" mean the fan is bad?
Also, the fan apparently requires a software upgrade: WR98R882802. Does anybody know what this does and if it's actually required?
