A chair lift allows handicapped and disabled people to stand after sitting. While a chair lift can be a valuable tool, it relies on many moving parts. The following guide provides simple tips for repairing a broken chair lift. Check to see if any object has become lodged in the lifting assembly. A book or remote control can drop between a lift chair's cushions, preventing a unit from working. If there are no obstructions in the lift assembly, make sure that all parts can move freely. If the unit continues to not function, it may be necessary to replace the lift motor.
