Garage Door Opener Problems

A garage door opener does a lot of work, often several times a day. When it stops working, it can leave your car stuck inside or your home less secure. Many problems have simple causes, while others need a professional. Here's how to troubleshoot common garage door opener issues safely.

A word on safety

Garage doors are heavy, and the springs that balance them are under high tension. Never try to adjust or replace torsion or extension springs yourself. That job is for a trained technician. The tips below focus on the opener and simple checks.

Before working near the opener, unplug it.

Problem: the opener doesn't respond at all

Start with the basics:

• Check power. Make sure the opener is plugged in and the outlet works. Check the breaker or GFCI outlet.
• Check the wall button. If the wall button works but the remote doesn't, the issue is likely the remote.
• Check the lock feature. Many wall consoles have a lock or vacation button that disables remotes.

Problem: the remote doesn't work

1. Replace the remote's battery.
2. Stand closer to the door to rule out range problems.
3. Reprogram the remote using the instructions in your opener's manual.
4. Check for interference from nearby devices or certain LED bulbs installed in the opener.

Problem: the door reverses before closing

This is one of the most common issues, and it's often caused by the safety sensors. These sensors sit a few inches above the floor on each side of the door. If something blocks the beam or the sensors are misaligned, the door reverses for safety.

Try this:

• Clear anything in the door's path, including leaves, cobwebs and stored items
• Wipe the sensor lenses with a soft cloth
• Check that both indicator lights on the sensors are on, as described in your manual
• Gently adjust the sensors so they point directly at each other
• Look for loose or damaged sensor wires

If the door reverses after touching the floor, the close limit or force settings may need adjusting. Follow your manual, or call a pro.

Problem: the motor runs but the door doesn't move

This can mean:

• The door is disconnected from the opener. Check whether the emergency release cord was pulled.
• A drive gear or sprocket is stripped inside the opener.
• The belt or chain has broken or come off.

Reconnecting the trolley is usually simple, but stripped gears and broken drives call for repair.

Problem: noisy operation

Grinding, squealing or rattling may come from the door, not just the opener. Check for:

• Loose hardware on the door and tracks
• Worn rollers
• A chain that needs adjustment

Many manufacturers recommend lubricating rollers, hinges and springs with a garage-door-specific lubricant. Don't lubricate the tracks themselves unless your door's manufacturer says to.

Problem: the door opens partway or stops

The door may be out of balance, the travel limits may need adjustment, or something may be binding in the tracks. An unbalanced door puts extra strain on the opener. With the door closed, pull the release cord and lift the door by hand. If it's very hard to lift or won't stay halfway open, call a technician to check the springs.

Simple maintenance

• Test the auto-reverse feature periodically, following your manual
• Keep sensors clean and aligned
• Tighten loose hardware
• Replace remote batteries before they die
• Schedule professional service for springs, cables and balance

Does a home warranty cover garage door openers?

Many home warranty plans cover the garage door opener itself, including parts like the motor, switches, sensors and drive. Many plans exclude the door, springs, hinges, tracks and remotes, so read the coverage list carefully. Some plans treat the opener as part of a systems package, while others list it as an add-on. Our claims page explains the general process.
