LiftMaster 75LM Illuminated Door Control Button
The LiftMaster 75LM is a lighted wall push button used for basic garage door opener control. It is commonly installed inside the garage near an entry door to provide simple open and close operation from a fixed wall location.
This control is best suited for compatible LiftMaster, Chamberlain, Sears Craftsman, and Raynor residential opener systems that use a standard two-wire wall button connection. It should not be assumed to replace every newer digital, myQ, or Security+ 2.0 wall control.
Common Use and Compatibility
The 75LM is commonly associated with older residential garage door openers that accept a two-wire momentary wall button. It may be used as a main control or secondary control when the opener terminals support a simple push-button input.
- Select LiftMaster residential garage door openers with two-wire wall control terminals
- Select Chamberlain, Sears Craftsman, and Raynor openers using compatible two-wire control circuits
- Commonly associated with older green, red/orange, and purple learn button systems when a basic wall button is supported
- Not recommended as a direct replacement for most yellow learn button Security+ 2.0 or myQ smart control panels

Technician Note
Do not replace a digital wall console with a basic push button unless the opener wiring diagram confirms it will work. If the existing control has menu functions, motion sensing, timer-to-close, programming buttons, or myQ features, a different wall control may be required.
Before Ordering, Confirm
- The opener accepts a standard two-wire wall button
- The original wall control is not a Security+ 2.0 smart control panel
- The wall button wiring is intact and not shorted
- The opener terminals are identified for wall control use
- The application only requires basic open/close operation
Professional Advisory
Disconnect power to the opener before servicing wall control wiring. Low-voltage wall button wiring should not be connected to line voltage. If the opener runs by itself, has intermittent control issues, or has damaged wiring, correct the wiring problem before installing a new control.
