Openers are a “working horse” of your entire garage door assembly, and for obvious reasons, they often do break. Most homeowners usually call a garage door technician, and the whole thing gets swapped out for a new one. However, some DIYers prefer to repair it instead of throwing away an opener which might be easy to fix. In this post, we’ll show you how to dig deeper into the issue and how to repair a garage door opener.
As a safety precaution, before you start doing anything to your opener, make sure the door is fully closed, and your garage door opener is unplugged. Once you verify it’s not connected to any power source, you can start unscrewing the back panel. In this particular example, we work with Chamberlain Opener which has two larger size screws at the top and a single smaller screw at the bottom.
Once you’re done removing the back cover, you’ll imminently get access to your opener’s internal components. At this stage, there are a few things you might want to look for.
