The items listed below are intended for repair of a LiftMaster operator and not necessarily for repair of a door.
MULTIMETER - Look for a meter that has an audio signal for continuity. To make working on a ladder safer and easier,
look for test leads able to grip onto the wire being tested. A high quality (expensive) multimeter is not required. A less
expensive meter will work very well for diagnosing electrical issues within an operator.
SCREWDRIVERS - Standard size Phillips and Flathead and a small size Flathead for setting DIP switches and working
with Logic “Daughter Boards” i.e. CPS3CARD, TLS1CARD, etc. Screwdrivers should be insulated.
SOCKETS AND CRESCENT WRENCHES - A 1/4” nut driver will be extremely handy. Crescent Wrenches and Socket
Sets are mainly for removing an operator from the door, wall or ceiling.
Additional Items:
Wire Stripper w/Crimping Tool
Wire Cutters
Needle Nose Pliers
Standard Pliers
Manual Winch - Used for lifting or lowering the operator safely
Jumper Wires w/Alligator Clips
NOTE: Use fall protection or harness and tether as necessary.
