Introduction
Does your LiftMaster only close when you hold the wall button down? You are not alone. This issue is common and usually simple to fix. In this guide, you will learn the causes and the fastest solutions.
Why Your LiftMaster Garage Door Won’t Close Without Holding the Button
Safety Sensor Problems
- Dirty lenses block the beam.
- Misaligned sensors make the LED blink.
- Objects in the doorway stop the door for safety.
Wiring or Power Issues
- Loose sensor wires at the opener or bracket.
- Damaged cables along the wall.
Control or Settings
- Wall control locked or stuck in “constant pressure” mode.
- Sunlight hitting the sensor eye at a sharp angle.
Step-by-Step Troubleshooting
- Clear the path. Remove bins, bikes, or toys near the tracks and sensors.
- Clean the lenses. Use a soft cloth. Do not scratch the glass.
- Check the LEDs. Both sensor lights should be solid. Blinking means misalignment.
- Realign the sensors. Gently twist each sensor until both LEDs stay solid. Tighten the wing nuts.
- Inspect wiring. Make sure the white and white/black wires are secure at the opener and at each sensor.
- Test the door. Press and release the wall button. The door should close without holding.
How to Realign LiftMaster Safety Sensors
Signs of Misalignment
- One or both LEDs are off or blinking.
- The door reverses or only works while holding the button.
Realignment Steps
- Loosen each sensor’s wing nut.
- Point both sensors directly at each other, about 6 inches off the floor.
- Watch for solid LEDs on both sensors.
- Tighten the wing nuts so they do not move.
Pro Tip
If sunlight floods one sensor, add a small hood or shade. A piece of cardboard or a manufactured visor works well.
Extra Checks That Often Fix It
- Wall control lock: Press and hold the “Lock” or “Vacation” button for 3–5 seconds to toggle it off.
- Remote batteries: Weak batteries can cause intermittent behavior.
- Door balance: A door that binds or is heavy can trigger safety reversal. Lubricate hinges and rollers, or call a pro for spring service.
When to Call a Professional
If sensors are aligned and wiring is good, the logic board or safety circuit may be faulty. Contact a LiftMaster-qualified technician for diagnosis and repair.
