Lazy Susans—those rotating shelves inside kitchen cabinets that increase the efficiency of your storage space and make items easier to reach—were first used as far back as the 1700s, according to a 2002 Jewish World Review article. Repairing a Lazy Susan, however, does not have to be a task out of the 18th century; the basic design of the Lazy Susan has not changed since it first appeared as a tabletop rotating platform a long time ago.
Remove the doors in front of your Lazy Susan for better access. A Lazy Susan operates on a suspension system that allows the table to turn 360 degrees. Most kitchen cabinet Lazy Susans have at least one platform, made of plastic or wood, attached to a pole mounted at the centre of the device.
Check the platform to make sure it is properly attached it the pole. A loose platform is a quick fix, requiring you either to install a new one or to replace or tighten any loose screws.
Tighten the bolts on each screw that holds the platform in place to make sure they are not causing it to come loose.
Check the ball-bearing pack at the unit's base. If the plastic casing has broken, or one of the ball-bearing rings has fallen apart, the little steel balls will have rolled out, causing the Lazy Susan to spin off-balance. On larger casings you can repack the ball-bearings yourself; otherwise, you're going to need to order the new part from the Lazy Susan's manufacturer. Once the new part arrives, follow the manufacturer's instructions to install it.
