When Bettendorf, IA, homeowners noticed the garage door motor was running, but it would not open, they knew something was wrong. So they contacted Titan Garage Doors Quad Cities for garage door opener repair. When our technicians arrived, we found the loose chain on the opener's rail. We quickly figured out what was wrong—the gears were stripped—and thankfully, we had the right gear kit to fix the issue. It only took us about an hour to replace the old gears and get their Genie chain drive opener working again. But that was not all — our team also noticed some rust on the chain itself, so we suggested replacing it at once to help prevent further issues. As everything worked perfectly, the homeowner was relieved there was no need to spend more for a new opener.

Most openers require an operator rail to raise the door. It activates several gears that turn a sprocket. The sprocket contains either a belt or chain, stretching along the entire operator rail. From there, a trolley attaches itself to the chain, which connects to the drawbar arm. That essentially causes the door to open when the chain is pulled. However, a lack of lubricant on these gears could cause them to wear out quickly over time.

Indications of Broken Opener Gears

• When you press your remote control, your operator hums, but nothing happens. It means your drive gear is moving, but the teeth have been worn away.
• A gear is stripped if you see white plastic specks on the floor. You can tap the bottom of your motor's housing, and the shavings should fall out.
• If you are unsure, open the garage opener case and look inside. The main drive gear is easy to notice. You should see a mix of white bits and worn-out teeth on the gear.
• If your opener chain is loose or dangling, there is a high chance that your sprocket is broken or bent. You must inspect the sprocket for damage, replace it, and tighten the chain.

Replacing gears and sprockets is simple to do on your own if you are a skilled person. You can purchase inexpensive gear online or at the nearest professional garage door dealer. Most dealers provide a gear and sprocket kit with instructions. To change the gear, unscrew a few fasteners and slide in the new gear. Always ensure that the newly installed mechanism is lubricated well. If you neglect to do so, the gears may weaken gradually within a few weeks.

Find the Source of the Problem

Before you fix your garage door opener, you should find out why it broke in the first place. If not, you will have to fix it again soon. If your garage door makes much noise when it opens and closes, it needs to be lubricated properly.

Check the Other Garage Door Parts

Additionally, it is recommended to inspect and replace any damaged parts, like the garage door rollers, if necessary. Carefully move the garage door off the track and see if the rollers can turn easily. Ball bearings can break down over time. If you neglect to care for them, they can cause more expensive and serious damage.


Having a working and secure opener for your garage door is paramount, and when something is not working as intended, it is best to call on the services of an expert. Attempting to fix the issue yourself can cause more damage or lead to more costly repairs.
