Liftmaster 41A4166 Lighted Push Button Entry Controls for Garage Door Operators
The LiftMaster 41A4166LM is a basic lighted push button wall control used with select LiftMaster and Chamberlain garage door openers manufactured from 1997 to 2011. It is designed for simple open/close control from inside the garage and connects to the opener low-voltage wall control terminals. The lighted button makes the control easier to find in a dark garage, but it does not add multi-function features. This is a practical replacement when the original push button is cracked, missing, intermittent, or no longer making reliable contact. Compatibility depends on the opener control circuit. It is not compatible with Security+ 2.0 yellow learn button models and should not be used where the opener requires a digital smart control panel or multi-function wall station.

Technician Note
If the opener works from the remote but not the wall button, inspect the button, low-voltage wire, and terminal screws. If the wall button wire is shorted, pinched, or stapled through, replacing the button alone may not solve the issue.
Before Ordering Checklist
- Confirm the opener was made between 1997 and 2011 or lists 041A4166
- Confirm the opener does not use a yellow learn button Security+ 2.0 system
- Confirm only basic push-button open/close control is needed
- Inspect wall control wire condition before replacing the button
- Do not use this in place of a required smart or multi-function control panel
Important Ordering Warnings
Wall button wiring is low voltage, but the opener should still be unplugged before service. If the opener starts by itself, has damaged wiring, or behaves erratically, disconnect power and have it inspected.
Professional Advisory
This button is not a universal replacement for every wall console. Newer Security+ 2.0 openers and smart wall panels use different communication requirements.
