Frequently Asked Questions
My garage door stops short and won't shut all the way. What should I check first?
The travel limits control how far your door moves when opening or closing, so if it stops too early or won't close completely, adjusting them is a good first step. Locate the travel adjustment screws on the opener unit, which are usually labeled "up" and "down," and turn them slightly with a flathead screwdriver. Test the door after each small adjustment so you don't overdo it. If the door still won't close flush after adjusting, it could be a sign of a warped track or a worn-out seal.
Is there anything I should do before I start adjusting the opener?
Yes, safety comes first. Be sure to unplug the opener or cut the power before you begin making adjustments. It's also a good idea to check your specific model's manual if you're unsure about which screws or dials to use.
Why does my door reverse or stall for no clear reason?
This can happen when the force settings need adjustment, since they control how much power the opener uses to move the door. If the force is too low the door might not open or close all the way, but if it's too high it can be unsafe around kids or pets. Slightly increase or decrease the setting while testing, aiming for smooth operation that still reverses if something blocks the door's path.
How do I know if my safety sensors are aligned properly?
Make sure both sensors near the bottom of the tracks are facing each other and set at the same height, then wipe the lenses clean with a cloth. Check the indicator lights afterward, since a solid green or amber light usually means they are working, while blinking typically signals a problem. Bumps, vibrations, or dirt can easily knock them out of alignment, which may stop the door from closing at all.
