Troubleshooting Garage Doors
Troubleshooting Garage Doors
Garage door problems can be extremely frustrating if you don’t know what’s wrong. Follow these steps for troubleshooting garage doors. To ensure that your garage door is working properly, we highly recommend searching for the “best garage door companies near me.” The following recommendations should only be performed if the power is turned off and the garage door is in the down position.
Garage Door Won’t Close
If your garage door won’t open or close, try the following garage door troubleshooting steps:
- Check that the garage door opener is plugged in and that the garage circuit breaker is in the proper location.
- Check to see whether your door has been manually locked by accident.
- Replace the keypad or remote control batteries.
- When utilizing garage door remotes, be sure you’re within the recommended range and position.
- Pull the emergency release cord – generally a piece of red rope hanging from the trolley – if you need to open a garage door that is stuck closed. The cord detaches the trolley, allowing you to manually open the door.
Safety: If you pull the release cord while the door is open, it may come tumbling down. Instead, contact a garage door service company in Sacramento.
Examine the External Garage Door Controls
If you’re having this problem when garage door openers are plugged in, the exterior controls, such as the wall switch, keypad, or remote control, may be malfunctioning.
- Test all of the controls.
- If the garage door opener motor has a remote control antenna, ensure sure it is undamaged and in the proper position.
- If the garage remote control has batteries and is being used within the proper range, it may require replacement. Universal garage door remote controllers are compatible with a wide range of openers.
- Consult the owner’s manual to reprogram or reset the remote control or keypad.
- If the remote control or keypad functions but the wall switch does not, the switch or button may be faulty or require replacement wiring.
- If you have a smart home, our friends at Specialized AV, who offers smart home installation, recommend checking your smart device to see if there are any visible problems.
Examine the Safety Sensors
If the garage door does not close completely, or if it closes and quickly reopens, there may be a problem with the safety sensors, which are designed to keep the door from closing on a person or object.
- Check that the safety sensors are pointed in the same direction and are properly aligned – use a level if necessary.
- To ensure that no debris is obscuring the eye, carefully clean the sensors with a soft cloth and a mild cleanser. Wipe away moisture and dirt gently, taking care not to harm the sensors.
- Check that no toys, flower pots, or other things are blocking one or both sensors. When there are no impediments, each sensor should have a little light that illuminates.
Pro Tip: Because strong, direct sunlight can degrade sensor function, make sure sensors have sun shields or are located in the shade.
Check Garage Door Opener
If the garage door opener receives power but still does not function properly, it may have a mechanical failure.
- If the door would not open, but the engine sounds like it is functioning, the primary gear drive may have broken and will need to be replaced.
- Does the trolley move, but without the garage door? One of the carriage’s components is broken and must be replaced.
- If nothing happens, the garage door opener motor’s circuit board most likely needs to be replaced.
- A chain drive garage door opener can have tension that can cause the chain to slip the sprocket and fail to move.
Examine the Garage Door Springs
The cables and torsion springs of your garage door are critical components in lifting the door. Garage door springs and cables wear down with time, and broken ones might prevent the door from opening. Replacing a spring might be risky, so hire a door expert instead.
