This kind of replacement part should be matched by the original part number, system type, wiring/contact style, and the equipment parts diagram. Similar-looking LiftMaster, Chamberlain, MMTC, or access-control service parts may use different connectors, contact behavior, voltage requirements, or programming steps.

Technician Note
Do not choose this part by appearance alone. Many LiftMaster and access-control service parts share similar housings or board layouts while using different firmware, connector locations, switch contacts, or operator families. Match the original part number and the equipment parts diagram whenever possible.
Before Ordering Checklist
- Confirm the model number on the operator, telephone entry unit, or access-control panel.
- Compare the original part number, label, and physical mounting style.
- For electrical parts, verify voltage, wiring terminals, connector layout, and system generation.
- For control boards, expect to reprogram remotes, keypads, limits, myQ settings, or access-control settings when applicable.
- For safety edge or pneumatic parts, do not bypass safety devices and confirm the required monitored or non-monitored input type.
Professional Advisory
If the equipment has damaged wiring, water intrusion, burned boards, unsafe gate or door movement, missing safety devices, or high-voltage electrical issues, have the system inspected by a qualified gate, garage door, or access-control technician before returning it to service.
