An automatic garage door works hard to open and close multiple times a day. However, if it suddenly refuses to open, there are several possible reasons why you are experiencing this issue. Below are some of the most common explanations so that you can determine if you need repair services.

Why Do Garage Doors Fail to Open?

1. Blocked Photo Sensors

The safety sensors that sit on either side of your garage door frame detect when an object is in the way, causing the door to automatically reverse. However, dirt, cobwebs, leaf particles, and other debris can block the eye that senses objects, resulting in signal interruptions that prevent operation. Clean the sensors with a soft cloth to see if it resolves the problem—if it doesn’t and the door is otherwise intact, the sensors likely need a replacement.

2. Dead Remote Battery

Sometimes the overhead door won’t open because the batteries in the remote are dead. Start by trying to use the opener inside the garage to see if it still works. If it does, check for corrosion on the battery terminals in the remote, then replace the batteries and try opening the door again. If you still have issues, the remote or sensor in the door could be faulty, preventing the transmission of the signal.

3. Broken Mechanisms

When the springs or cables that allow a garage door to open and close break, the door will no longer operate. Always schedule professional repair services if you believe a broken spring or cable is to blame for your malfunctioning door. While usually due to wear, both issues can cause the door to drop suddenly, possibly injuring anyone below without professional handling.

4. Alignment Problems

If debris accumulates in the tracks or the metal bends due to damage, the garage door cannot operate properly. You will likely hear the door squeaking or grinding, and it may become stuck during operation. While you can remove debris, if the metal is bent or has other damage, it needs professional repair services. Continuing to use the door causes further track damage, potentially requiring a full replacement.
