3 Valuable Tips for Diagnosing a Roller Garage Door Sticking Problem

Posted on: 21 January 2021


A garage door is an essential access point to a home for vehicles. When a garage door malfunctions, it can get really frustrating for homeowners. For example, it means that your car is stuck inside or locked out of your garage. Whichever the case, you need professional help to get a garage door working correctly. Here are some tips for diagnosing common garage door problems. This article specifically examines roller garage doors.

Adequate Tension

The proper functioning of a roller door is dependent on the right amount of tension in the chain that moves the door up and down. Over time, the chain can become too tight or loose, meaning that the door won't open or close seamlessly. If the chain has excessive slack, it can easily fall off its sprocket. Conversely, a very tight chain can lead to quick wear and tear of a roller door's essential components. Therefore, if you experience changes in tension, you should seek professional help to remedy the situation.

Garage Door Opener Issues

There are different garage door opener configurations that you can find in residential garages. Some of the standard models include chain-driven, sensor-activated, and belt-driven. Everyday usage can cause the opener to get damaged due to increased wear and tear. One sure way of diagnosing door opener problems is to pull the manual cord, which hangs from the door track. Engaging the cord disables the automatic opener, enabling you to use the manual mode. When you pull the cable, and the door moves freely up and down, the problem lies with the door opener and not the door itself. In this case, you can troubleshoot the opener by following the manufacturer's manual. Alternatively, if the opener requires repairs that you are not comfortable performing, you should contact your a door repair expert.

Safety Sensors

If your garage door goes up but fails to come down properly unless you engage the wall switch, the problem might be with the safety sensors. You should try adjusting the sensitivity settings of the garage door sensors. A high setting can prompt a garage door not to close because of the assumption that something is obstructing its path. However, if adjusting the sensitivity setting does not work, the problem could lie elsewhere, such as a faulty sensor. Failure to spot any light display might point to faulty sensors that need replacement. Note that when swapping sensors, you can save time and money by retaining existing wiring.

If you notice any of these issues, contact roller door repair companies.
