The LiftMaster K23-10041 Commercial Limit Switch is a genuine OEM replacement switch used on select LiftMaster commercial door operators to control travel limits. Installed in the operator’s limit mechanism, this switch is actuated by the rotating limit cams to signal the system when the door has reached its fully open or fully closed position, helping prevent over-travel and ensuring consistent stopping points. It’s a common service part for commercial and industrial garage door openers operating sectional or rolling steel doors in warehouses, loading docks, and similar applications.
Use the K23-10041 to replace a worn or failed limit switch and restore reliable limit control on compatible LiftMaster jackshaft, hoist, or trolley-style commercial operators. Installation typically involves mounting the switch in the existing bracket or housing, transferring the original wiring to the same terminals, and readjusting the open and close cams per the operator’s service manual. After installation, disconnect power and follow lockout/tagout procedures, then verify and fine-tune travel limits and test all safety devices. For compatibility, consult the parts diagram or technical documentation for your specific LiftMaster commercial operator to confirm it calls for part number K23-10041.
