I just want to say thank you for such a clear and concise explanation. All other videos went off on a tangent. You were straight to the point!

Readjusting coordination, cleaning the lenses, and checking the wirings of the sensors solved my issue(s) thanks to what I learned in this video. Thank you very much! 🙌🏼

Sam, thank you so much. I just cleaned the lenses on the sensors and the garage door closes and works as it normally does. As a person who is not "handy" I find your videos very informative and easy to follow.

I was getting frustrated after hrs fiddling with the darn thing and about to call a repairman who would've told me who knows. I was fooled because the sensor lights were on. But the light would blink right before it closed and go back up. So after watching your video I kept my eye on the sensors as the door was closing. Sure enough the side rail shaking on the left side caused the sensor rays to disconnect and caused the door to go back up. But you pointed me the right way anyway. I was at my wits end. What a blessing your video was. Thanks.

Thank you! Tried your suggestion with aligning the sensors and it worked! Appreciate it. It’s not often where one of these fix it videos actually is helpful.

The trim at the top of my door partially detached from the frame and was catching the door about 80% down then it would go back up. I nailed the trim back into place and that fixed the problem. Thanks for the tips in the video too.

Thank you SO much for making this video ! As a recently widowed elderly woman, I was able to fix my garage door closing problem without having to call an expensive repair person.

Thank you so much for this video Sam. I was fooling around with no idea why the door all of a sudden stopped going fully down. I check the sensor to wipe them and sure enough just like you said, there was a dried leaf 🍁 stuck on the left sensor totally covering it up. I removed the leaf and wiped down the sensor and the door is functioning once again. I’m super grateful for you instructions.

Excellent. Well presented. Lens was a little dirty but one of them needed wing-nut tightening and trial and error to re-aim the beam.

A very clearly presented video that gave me the exact reason why the door wasn't closing. An easy fix and I didn't have to rely on a service call with a high fee. Thank you!!

Thank you for a very complete look at potential problems.

Thank you so much for your most comprehensive explanation. Tightening the sensors and cleaning the lenses did the trick. God bless!

Exactly what u said the sensor was hanging so wouldn’t close... all fixed and working.. thanks for the info!!

Best how to video I’ve seen yet! Thank you.

Thank you so much, your solution worked, the sensor was loose. You saved me $150 that I would've had a pay for a service call. Much appreciate you posting this video!

Excellent presentation, concise and to the point. My lenses were dirty due to recent garage floor scrapping, clean them, readjusted and voila - it work. Thanks

Thanks so much! I watched the first 1:30 and realized my problem. So satisfying to fix something yourself without having to call a repair service for $150. Much gratitude.

Thank you so much for your video!!! I couldn’t closed my garage door today and it worked after I cleaned the sensors!!! So glad I went to KZfaq for solution.

Thanks! You literally just helped me avoid a service charge fee. Keep it up!

Thank you, sir, for posting this video. It was super helpful to me today. My door was not closing. It would start then stop. Turns out that it was the sensor! Someone bumped it when they picked up some things today. You have been a great help. Thank you again.

In just five minutes you helped me correct my garage door problem. Thank you very much.

My garage wouldn't open or close without having tondo it manually. As soon as i wiped my finger across the lense (as this video suggests could be a reason) and pressed the button, it closed and opened... I thought it was probaby the chain but it was that the lense had dirt on it... This man knows his stuff!!! Thank you for this video!

Thanks! Today our door did just what you showed in the video. As instructed, checked wiring, cleaned the glass (did not know these existed) and made sure they aligned with each other. Presto, door works. Assume the lenses were dirty. Thanks

Great tutorial! I learned a lot from this video and easily fixed my garage door problem and saved hundreds of dollars. Thanks,

Thank you for your Awesome videos. My BFF had a meltdown about her garage door when it didn’t want to close. Thank you for telling me some ways to help her out.

Thank you. Cleaning the lens worked. Much appreciated

I was about to file a home warranty claim, when I watched your vid and then went out and cleaned my sensor lenses. That fixed it! You saved me $75 and time. Thank you!

Thank you for taking the time to share this valuable information. Much appreciated!

I called the garage door repair guy to come out. He said $85 just to come out. I looked at your channel. I was done in 30 seconds. Just cleaned the lenses. It had very little dust but it worked. thank you .

Great Illustrations! Simple to follow. Was able to get garage door working on the third illustration. Wires got separated by a snow shovel resting on the wire nut.

Thank you for giving some good information on Garage Door Repair.

This video was extremely helpful. My garage door shit the bed, or so I thought, then after this extremely helpful video I was able to fix it quickly. One of the best videos I found on KZfaq thanks again.

This just happened to right now. Found this video while trying to find a solution myself. Thanks a lot for the video. Solved the issue instantly. 2 reasons why mine wouldn't work. A spider was just chilling on the right and also the was sensor pretty lose. Cleaned both of them and propped the right sensor now it works perfectly fine. Thanks again

You saved my life tonight!!! THANK YOU SO HELPFUL IT WAS THE FRIGGIN SENSOR!!

Thank you Sam!! I was able to fix my door all by myself! God bless you!

Sam, THANK YOU so much...! Fantastic demonstration to resolve a menacing problem, without spending hundreds of bucks for a technician. Especially, a lot of people don't realize how important it is to clean the lenses after you cleaned up a dusty garage. My wife inadvertently disturbed the alignment of the sensor unit while sweeping with a broom :) (exactly as you explained here). I knew how to get the steady and solid green light back with a little adjustments of the sensor unit...... I even wiped the lens area of the receiving unit with my finger, but still the door didn't close fully and went back with the same blinking overhead light (INSTEAD of the proper alignment of sensor units and SOLID Green Light). I didn't know what else to do and luckily found your video here before calling a technician. I cleaned up both the lenses with a lint-less cloth, using the lenses & monitor screens cleaning volatile liquid. It WORKED perfectly to resolve the issue. Thanks again for this very informative and helpful video.

I was able to fix it right away. Thank you for stopping my cursing.

really amazingly helpful video cover all different potential causes all together, short and concise!

You saved my day. I was on my way to the airport when all of the sudden the garage door did not want to close. This could not happened on another day but the day going to airport. I checked the sensors and they were very dirty. I cleaned them up and problem solved ......... thank you !!!!!!

Thanks to you I fixed my garage door easily! Loose wire from sweeping around the sensor! Thanks!

Thanks! Cleaning the lens did the trick, though it didn't look that dirty. I also unplugged the garage door box to reset it.

THANK YOU!!! Cleaned the sensors. Problem solved. I probably never would’ve thought of that, called a garage repair guy and been told I needed a new garage door or some expensive (and needless) repair.

Thank you! I was able to fix my door after a week of problems, you made it easy!!!

Thank you! I thought I might have to call a repairman but I fixed the problem with your helpful video😊

You are a life saver! Thank you, just fixed my garage as well from your video

I just fixed my garage door that would not close using the tips shown in this video, thank you so much!!

Thankyou! after reading my manual and getting frustrated, I found your video. The lens had a nice little cobweb over it. Thanks again.

You made my day. Thanks for saving me a lot of headache and money

Thank you so much...very informative and makes sense!!!! Going down to garage now to fix my door!!!!

Very good video and information. Cleaning the sensors and tighten one fixed my problem! Thank you so much !

Thanks so much for this video! It saved us from having to call a service person to solve our door problem!!

This was the best diy video for my garage issue. it was the vibrating and dirty lenses. Both issues were taken care of!

Very clear and concise video. Now I'll go and troubleshoot my garage door.

Cleaning the lens worked like a charm. Thank you very much.

Thanks a lot for the video. It's very helpful!

Excellent video, instruction explanation. Fixed my door! Thanks for uploading.

Thank you for this video! I just go a garage door opener and today it would not close and the place I got it from is closed for a 3 day weekend. I was very worried about leaving the garage open - but you saved the day.

Sam is the truth! Thank you for this tips. Just moved to a new house and door was stuck when closing. Just figured that one of the sensors was hanging by a zip tie. Seems like vibration got the tie moving and the sensor was loose pointing to the ground. Got the sensor back in the right position with the zip tie and it is operating back again. I'll take a look to see if why there is no screws holding the sensor, like in the other side, to figure out a better solution to the issue.

Excellent instructions! Cleaning the sensors worked out perfectly!

Thank you so much for your video. My friend changed the opening code for me and then I was having issue with the door closing. I never in my wildest dreams thought your idea of the eye being dirty was the right answer. Guess what it was. You saved me money, thanks again.

Exactly the problem! Please continue to educate us on the mechanics of our World!

THANK GOD FOR YOU AND THIS VIDEO!! YOU SAVED ME 🙌🏾🙌🏾🙌🏾🙌🏾🙌🏾🙌🏾

Thanks! The wires on one end were loose and after fixing them everything went back to normal! 👌🏽

Easy to understand Adam very helpful

I just followed this video and finally got my door to close. There were spider webs on both sensors. As soon as I cleared these the problem was solved. Thank you!

You’re a life saver! Just cleaned my sensors and it closed right up!

Thank you soooo much, I was able to fix my door thanks to your video.

Wow very useful. I thought I’d have to hire someone but it’s really just so simple.

Thanks for the video. I think the cleaning of the lenses did the trick for me! Just in case, I got down and checked my wires, shook the rails and all that. My wife now thinks I’m a legitimate handyman. I owe you, man!

Thanks, I'm gonna check out all 4 reasons to see what could be the problem. We have a lot of snow against garage door and thought the eye might be frozen, but we'll see!

Thank you so much - very clear video that just let me troubleshoot and correct my sensor issues. Thank you!

Thank you! I was having trouble with a job we had to finished. I really appreciate it

Exactly what was wrong and is now fixed. THANK YOU!

Great video. One other issue I ran into; same problem, but different solution. The screws holding the rollers onto the door (and the braces for the door) were all loose. It caused the door to shake and prevented it from closing. Tightened the screws and the door closed just fine.

Thank you sir.lenses were loose after watching lots of videos this was the one that did it.once again thanks

Thank You!! After your video and rechecking the door it works fine. You saved me a service call.

Thanks for this! I moved the sensor by mistake and didn’t realize this was an issue!

Thanks Sam! Cleaning the lens did the job. Cob webs and dust.

My sensor was loose and this video helped me realize that! Thanks a lot!

Thank you for this video. My door wasn’t closing, after cleaning the sensors it closed. Excellent information.

An older door opener was intermittently not closing and I was getting frustrated with it. After watching your video, I cleaned and adjusted both safety sensors, verified steady LED lights on them, and now again have a working door opener - at least for now...
