This DIY repair guide explains how to replace the wall control for a garage door opener. Located on the garage wall by the door to the house, the control opens and closes the garage door and turns the garage light on. If nothing happens when you push the control button, the control is most likely broken. Replace the wall control with the manufacturer-approved replacement part.

Use this procedure to replace the wall control for Craftsman, Chamberlain, Genie and LiftMaster garage door openers.

If you have to hold down the control button for the door to close completely, the safety sensors are the most likely problem. To replace the safety sensors, see our repair guide How to Replace a Garage Door Opener Safety Sensor.
