How Do You Install a LiftMaster Garage Door Wall Control?

What should be checked when installing a LiftMaster wall control?

Confirm opener compatibility, disconnect power, identify the correct low-voltage conductors and terminal polarity where required, make clean connections, mount the control securely, restore power, and test each supported function.

What to watch for

• Verify the wall control is compatible with the opener model.
• Document conductor placement before disconnecting the old control.
• Keep exposed copper out of adjacent terminals.
• Test door command, light, lock, and connectivity features after mounting.
