This blog post offers a comprehensive guide to troubleshooting a garage door that opens unexpectedly.
Common Causes of Garage Doors Opening Randomly
Understanding the potential reasons behind a garage door opening on its own is crucial in effectively diagnosing and resolving the issue. Below are some common causes:
- Remote Control Issues: Malfunctioning remote controls can send unintended signals to the garage door opener.
- Electrical Interference: Nearby electrical devices can interfere with the transmitter signals, leading to erratic behavior.

Step-by-Step Troubleshooting Guide
Follow these steps to troubleshoot your garage door opening randomly:
1. Check the Remote Control
Start by examining the garage door remote control:

2. Inspect the Wall Control Panel
Next, check the wall-mounted control panel:
