Problem Description

Your myQ app opens the garage door fine but gives an error when trying to close it. The app shows close error or unable to close leaving your garage unsecured. Chamberlain requires the myQ door sensor to confirm door position before allowing remote close and this sensor is the root cause of most close errors.

Symptoms

  • App opens door but gives error when trying to close
  • Close button grayed out or shows close error
  • Door starts closing then reverses back open
  • App says door position unknown or sensor not responding
  • myQ shows door open but wall button closes it fine
  • Close command works sometimes but fails most of the time

Recognize these? Here's what usually causes it.

Common Causes

  • myQ door position sensor misaligned or battery dead
  • Sensor magnet too far from sensor on door
  • Safety photo-eye sensors blocked or misaligned
  • Door obstruction triggering safety reverse
  • myQ sensor battery depleted preventing position reporting
  • WiFi connection too weak for reliable command delivery

Most fixes happen in the first 3 steps.

Warning

Never bypass safety photo-eye sensors. These prevent the door from closing on a person child or pet. A closing garage door exerts hundreds of pounds of force. Fix sensors rather than bypassing them.

Step-by-Step Solution

1

Fix the myQ Door Sensor

The myQ tilt sensor on the top garage door panel tells the app if door is open or closed. If battery is dead or it shifted the app refuses to close. Replace the CR2450 battery. Verify sensor is mounted flat on top panel and LED blinks when door moves. Sensor and magnet must be within 1 inch when door is closed.

2

Clean Safety Photo-Eye Sensors

The two sensors at bottom of door tracks must see each other. If dirty or misaligned the door reverses when closing. Wipe both lenses with soft cloth. Each should show solid green LED. If one shows amber or flickers the beam is misaligned. Adjust bracket until both show solid green.

3

Check for Obstructions

Walk the entire door path checking for anything blocking sensors or door travel. A broom handle near the sensor a leaf on the lens or a box too close all trigger safety reverse. Move everything 6 inches away from sensor beam and door travel area.

4

Test with Wall Button

Press the wall button to close the door. If it closes fine but app does not the issue is the myQ sensor or WiFi not the door mechanism. If wall button also fails the problem is safety sensors or opener itself.

5

Improve WiFi Signal

The myQ hub needs strong WiFi for close commands. Check hub LED. Solid blue means good WiFi. Blinking blue means weak. Move hub closer to an access point or add WiFi extender in garage. Cloud verification is required for remote close.

Quick Solutions

Replace myQ door sensor battery
Realign sensor and magnet on garage door
Clean and align safety photo-eye sensors
Remove obstructions from door path
Move myQ hub closer to router
Check for objects near safety sensors

Still having issues? This is usually the deeper cause below.

If this comes back after following these steps, check whether a recent app or firmware update reset a default setting — the fix works, but the setting gets reverted silently.

Pro Tip

The myQ app adds a 10-second delay with beeping before closing remotely. This is normal and required by UL safety standards for remote garage doors.

Real-World Insight

Battery-related failures are almost always flagged too late — the device degrades silently for days before the app catches up to what's actually happening.

What Usually Goes Wrong
  • myQ door position sensor misaligned or battery dead
  • Sensor magnet too far from sensor on door
  • Safety photo-eye sensors blocked or misaligned
  • Door obstruction triggering safety reverse
