I push the yellow mode button twice, which is supposed to cycle through the four dispenser arms and insure that they all return to their proper positions. But only two of the arms move. I believe there are two small motors, one providing power to two of the four arms, and of course the other for the remaining two. Is one of the motors shot, or am I just doing something wrong? Thanks.

The main culprit is usually corrosion. The motor could be bad but this is uncommon in most repairs. You should also check the dispenser ribbon connection to the main board in the changer.

Thanks V-man. You were dead-on with this one (corrosion)!
