My garage door opener just hums, what is going on?

Most of the time, especially if you have a Chamberlain or LiftMaster brand door opener, this means that the main drive gear inside of the opener is worn out and no longer making contact to turn the sprocket assembly.

This is another instance where we inform our customers and let them make their own decision because the exact lifespan of an opener is impossible to predict. The average lifespan of an opener is somewhere between 12 – 15 years depending upon the size of your door and how often the opener is used. If your opener is in this age range you may want to consider replacing the broken unit with a new one (new factory warranty, new ADAM Door warranty, etc.). Replacing the main drive assembly is somewhat of a gamble on older units. We have replaced the assemblies in some units and they have lasted for many more years while others may last only a matter of months. In either instance we will always check the spring balancing of your door as this can sometimes be the cause of a worn out drive gear – another good reason to have your door serviced each year.

We will gladly install a new gear assembly for you if you like, or if you’re a mechanical person and you’d rather install it yourself you can drop by and purchase one anytime.
