Some Whirlpool refrigerators have retractable rollers below the rear corners that make moving the appliance easier. With the rollers stowed away, the refrigerator rests on the leveling screws as the manufacturer intended. You may need to extend the rollers before you move the refrigerator to a new location; retracting the rollers lowers the appliance onto its leveling legs. You may need to unplug the refrigerator to access the rear legs.
Move the refrigerator forward so that you can comfortably access the back panel. You may also need to unplug the appliance.
Locate the rear roller adjustment bolt next to the rear roller in each corner. The bolt is positioned inward on the roller.
Turn the adjustment bolt clockwise with a 3/8-inch socket wrench to raise or counterclockwise to lower the roller. With each turn the roller moves downward or upward. Turn the bolt in the opposite direction when you are finished.
