This problem was solved by replacing the Compressor Start Device and the Run Capacitor. These parts must be accessed at the back of the unit by removing a panel at the bottom of the rear. Very simple repair requiring just a nut driver, a small straight-blade screwdriver, and a pair of needle-nose pliers. Most of your time will be spent clearing out the refrigerator and freezer compartments so that the unit may be rolled away from the wall.
