Why Does My MyQ App Say the Door Is Open When It's Closed?
- Door tilt sensor magnet shifted or fell off
- Sensor mounted wrong / on the wrong surface
- Sensor low battery (intermittent signal)
Problem Description
Your myQ app shows the wrong door status - open when it's actually closed (or the reverse), or the status lags by minutes. This traces to the door position sensor, which myQ relies on to know whether the door is open or closed. A shifted magnet, dead battery, wrong orientation, or a sensor out of range of the hub all cause a wrong or stale status. This guide covers the sensor checks that fix it.
Why This Happens in Real Homes
myQ knows whether your garage door is open or closed from a tilt sensor mounted on the top panel of the door - it reads vertical when the door is down (closed) and flat when the door is up (open). So a wrong or stuck status is almost always a sensor problem, not a hub or opener fault. The most common causes are a magnet or sensor that has shifted or fallen off the panel, a sensor mounted on the wrong surface or in the wrong orientation (the arrow needs to point along the direction the door travels), or a dead battery causing intermittent reports. Re-securing the sensor correctly on the top panel and replacing the battery with a fresh CR2032 (or CR2, depending on model) fixes most cases.
The other half is signal. The sensor talks wirelessly to the hub, and if it's out of range - or the hub's own WiFi is weak so it can't push updates to the cloud in real time - the status lags by minutes or sticks. Moving the hub closer to the sensor, improving the garage WiFi, and re-pairing the sensor in the myQ app resolve those. This matters beyond annoyance: because myQ requires the sensor to confirm the door is open before it will send a remote close (a federal unattended-close safety rule), a flaky sensor can also block closing the door from the app, so getting it right restores both accurate status and remote close.
Symptoms
- App shows open when the door is closed (or vice versa)
- Status lags minutes behind the real door
- Auto-close keeps triggering on a closed door
- Repeated open-door alerts when it's shut
- Status flickers open/closed
- Sensor readings seem reversed
- Status stuck and never updates
- Started after moving or replacing the sensor
Recognize these? Here's what usually causes it.
Common Causes
- Door tilt sensor magnet shifted or fell off
- Sensor mounted wrong / on the wrong surface
- Sensor low battery (intermittent signal)
- Sensor orientation wrong (arrow not along door travel)
- Weak hub WiFi delaying status updates
- Sensor out of range of the hub
- Metal door interfering with the signal
- Sensor lost pairing with the hub
Most fixes happen in the first 3 steps.
Garage doors are extremely heavy and the springs are under high tension. Never attempt to repair or adjust the door springs, cables, or tracks yourself as this can cause serious injury. Only troubleshoot the smart controller and electronic components. Call a professional for any mechanical issues.

Step-by-Step Solution
Check the door sensor placement
The myQ door sensor is a tilt sensor mounted on the top panel of the garage door. When the door is closed, the sensor is vertical. When the door is open, the sensor tilts to horizontal. If the sensor is mounted on a lower panel or at an angle, it may read the wrong tilt position and report incorrect status. Reposition the sensor on the top panel of the door, centered horizontally, with the myQ logo facing toward the ceiling.
Replace the sensor battery
The myQ door sensor uses a CR2032 coin cell battery. A low battery causes delayed or incorrect status reporting. If the sensor occasionally shows the wrong state or stops updating, replace the battery. Pop off the sensor cover, replace the CR2032, and reassemble. After replacing, open and close the door to confirm the app status matches the actual door position.
Check for WiFi interference affecting hub communication
The myQ hub communicates with the cloud to update status. If the hub WiFi connection is intermittent, the app shows stale status — it might show Closed when the door is actually open (or vice versa). In the myQ app, check the hub connection status. If it shows offline or the last update time is old, restart the hub (unplug for 15 seconds). Move the hub closer to the router if WiFi signal is weak.
Recalibrate the sensor
In the myQ app, go to your garage door device > Settings > Sensor. There should be an option to recalibrate or re-pair the sensor. Close the garage door fully. Trigger the sensor calibration. The sensor registers the closed position tilt angle. Open the door fully. The sensor registers the open position. This recalibration fixes status issues caused by sensor drift or mounting angle changes.
Check for multiple controllers conflicting
If you have both a myQ-enabled opener (built-in WiFi) and a separate myQ Smart Garage Hub, they may conflict — both try to report door status but give different readings. In the myQ app, check if you have duplicate door entries. Remove the duplicate. Use either the built-in opener WiFi or the external hub, not both on the same door.
Quick Solutions
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.
Set a nightly auto-close schedule at your usual bedtime so the garage door closes automatically even if you forget. Combine it with a phone notification 10 minutes before so you know it is about to close.
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.
- Door tilt sensor magnet shifted or fell off
- Sensor mounted wrong / on the wrong surface
- Sensor low battery (intermittent signal)
- Sensor orientation wrong (arrow not along door travel)
- Weak hub WiFi delaying status updates
