Garage Door Opener Stops and Reverses 

You, my good sir, are a wizard!!! I couldn't figure it out and thought it was a programming or wiring issue since I would have to hold down the switch to close the garage door. Saved me time, money, and a heavy load of disappointment! Simple fix, video goes step by step and gives detailed instructions and explanations, audio and video quality were great. My first impression was completely wrong about you and I apologize for judging you by the first 15 seconds in your video. Therefore I destroyed the like button and subscribed! Greatly appreciated 🙏🏽👍🏽

Thanks, Mike, for this very well-laid-out video on garage door issues. I watched the video completely through last night and then particular segments this morning. I went to the garage about 11 am and took on the challenge and within an hour, had the door operating like new. For a 73-year-old, totally disabled man, with your instructions, I felt like a young man doing a weekend project. Yea!!!

THANK YOU!!!!! We cleaned the sensers and it still didn't go down. Then, I simply moved one a tiny bit upwards, and Voila! Tighten the wing nut and no serviceman or $$$ needed. You are the Best!!

You’re a Godsend Mike! I was getting frustrated trying to figure it out by myself; but after watching your video I fixed it within minutes! You’re amazing! Thank you so much!

Mike, Thank you so much. Your clarity and description of the sensor problem was all new to me. In my case , the visual blockage to the other sensor was resulting from a spider web array on the sensor and a slight adjustment of the wing nut. Wow! It all worked 1,2,3. Thanks Again. Five minutes and a problem that I have been experiencing for several months was solved.

😢 Thank you so much for this. You saved me from paying $$$ to have someone come out to troubleshoot/fix the issue. As a single woman who knows very little about home repairs, videos such as yours gives me more confidence when it comes to repairing small things myself. My sensor was knocked out of place and was not pointed towards the other and I lined it up just as you showed and voilà the door started working. Thank you so much. I’m definitely subscribing.

I’ve been so stressed not knowing what was wrong with this door! Thank you! Simple yet very useful tips just saved me hundreds of dollars.

Yes! Thank you for posting this. You just saved me from having to call my husband 3000 miles away at work.

This was the exact issue with my garage door, and your advice was right on target! Problem solved. Thanks much, Mike.

Thank you so much! My fiancé and I just closed on a house two days ago. I woke up this morning and this happened. You’re a life saver!

Thank you. We never knew how to fix this problem. We have paid a lot of money over the years to have this same problem fixed repeatedly and you just explained it and it was so fast and easy and you made it so understandable.

Thank you! I added a garage door opener on my Jeep and couldn't figure out why it wouldn't work! Turns out it's just early morning and the sun is shining on the sensor. You are a genius!

I have been dealing with this issue for about a month or so...so glad that I came across your video. Such an easy fix!!!! Thank you!!

Thank you! You solved my problem. My garage door would not fully close; it kept reversing open. Thanks to your video, I realised that the morning bright sunshine was hitting one of the sensors. Only happens seasonally when the morning sun comes from the northeast direction; the rest of the day the north-facing garage is in shade. What a relief!

New house. First time ever having a garage door opener. A single woman was able to repair it with the help of your video! Thank you so much!

Loved it, it took me 5.05 minutes (your video duration) + 1 minute to fix my garage door issue :). Amazing video! Thank you for posting it!!

Perfect advice! I was having the same issue. And while I thought it might be the sensors , and even cleaned the glass, I didn't think about the alignment. Thank you so much! You saved me some bucks.

This was ABSOLUTELY the problem my door was having. Thank you for showing me how to fix it!! Woohoo! 😁👍🏼

Short, easy to understand, and straight to the point, and solved my problem. You just saved me $200.00. THANK YOU.

Thank you! I swept the floor and then had a non working opener. I followed your instructions and reset the positioning of the sensor, tightened the wing nut and MAGIC! Your well done video saved me money, time and frustration.

THANK YOU SO MUCH FOR SAVING ME FROM HIRING SOMEONE TO FIX MY GARAGE DOOR. 😽 (I used to call my very handy Papa but he passed 2 years ago and I feel a little lost without his wisdom.)

Thank you!!! I've been screwing with my garage door for two days and you fixed it in five minutes and six seconds! I ordered new sensors yesterday but they weren't bad, just not aligned. OUTSTANDING!!!!!

Thank you, Mike. Suddenly had trouble with my opener. It kept reversing. I went through all the things I knew to look for. Sensor out of line, loose wire...etc. The sun was coming in a side window at just the right time of day and blinding my sensor. I never would have figured that out in a million years without your video. Thanks

Yesterday evening my garage door started to do exactly this. Would not close and kept popping back up again. I did exactly what Mike said and WOOO HOOO it worked!!!! THANK YOU SO VERY MUCH FOR THIS INFO. So happy!!!!

It's the worst when you come back from work and the door is playing up you don't want to stand there and press the button until the door goes down or in the morning trying to get to work on time thank you so much again.

This evening my garage door started automatically going back up, everytime it got about a foot from the ground when I was attempting to close it. I tried to close it about 10 times, and got the same result every time. After doing some troubleshooting, I discovered that my issue turned out to be a loose bracket that held one of the sensors to the wall. Whoever installed the system before I bought the house, used nails to secure the brackets to the wall instead of screws. So the nails in one of the brackets had loosened a bit, allowing the bracket to slightly vibrate once the bottom of the door was near the sensor. As a result, and while the sensor bracket was vibrating, the sensors got misaligned for a slight moment, triggering the safety mechanism. I replaced the nails with screws and the problem was solved.

If the overhead unit light is not blinking, it is not an alignment problem with the sensor; it may be that the down force needs to be adjusted i.e. increased. If the door when taken off the opener moves up and down freely, that may be the solution. The force can be changed via the screws at the back of the motor unit, one is for down and one is for up force.

Thanks - this was my problem. In five minutes resolved the garage door stopping and reversing back open! My wife is a happy camper and so am I!

Mike, I just took a look at your video and cleaned the sensors, brushed away some fairly heavy dust and it worked!!! My garage door was sticking upon opening and now it works perfectly and even seems to be opening more smoothly than before the problem occurred. Thanks, man!

My garage door opener will not close if opened or will not open if closed. Following this video, one of the sensors does not have a green light. I climbed up to the "motor unit" and wiggle the wires that connect to the sensors. One of the wires was loose and can easily be pulled out. I pull the wire all the way out and push it back all the way in. Now I have a green light on each sensor. Problem fixed. I almost call the garage door opener people!

My hero! I've struggled with my garage door way too long. Then there was you. Thank you.

I want to thank you for this video, I have had this issue for more than 1 year!!! I was scared to think it would be crazy expensive for a fix, it was the sensor that was out of line, you are very awesome, sir!!

My problem was not included in the video, so I thought I would mention it. The curved arm that attaches the trolley track to the garage door has two bolts/nuts on my door. I did not realize that one of the bolts had fallen out. The arm was no longer straight and it ended up literally pushing the top of the garage door down at it's top instead of "pushing" the door down from the point where it is mounted. Then, the mounting point where the manual release is attached came loose. I found the original bolt and added a new nut and then re-affixed the locking portion into the base where it locks.......this solved the problem. The garage door was stopping about a foot or more above the ground because it was just pushing the garage door down from the top. Hope this helps.

Adjusting the sensor fixed my issue. I didn’t know about the flickering light as a indicator that it might be off just a smidge. Thanks!

Grass from the weed wacker....... man I feel foolish. I didn't know about the sensor lights... SO simple... thanks for the video!!!

At last - a video addressing my exact issue! Garage door would begin to close, then reverse about a foot before fully closing, and the main unit would blink. The previous homeowners screwed the sensors on its sides so I couldn’t see the green lights unless undoing the wingnuts (didn’t even know they were there until I watched this video). Thank you!

Thank you! This is exactly what it took to fix my garage door problem.

I would like to thank you so much. I am a single woman with two grown children and I am not savvy when it comes to fixing things I tend to always call people who probably charge me a lot of money to fix simple things. But watching your video I was able to do an easy fix on my garage door you were very descriptive and helped me solve my problem. I am definitely going to subscribe you are a lifesaver!

Sir!!! This is a top notch video!!! You explained it in more simple terms than just "Line up the sensors." I never paid attention to the lights before!!!

Been living with this unclosing garage for days. All fixed with your info. You’re an angel for posting. Thank you!!!!!!!!

wow it was that simple. I really thought i broke the garage door lol thank you so mhch!!

Thank you so much im at a friend's house and thought I broke it and if I didnt fix it I'd have to pay for a new one but luckily this helped!!

This is super helpful. My garage door has exactly the same problem. Your diagnosis and fix in the video are so clear that I was able to easily fix mine by adjusting the scanner's position. Thank you, Mike!

Just wanted to say thank you so much Mike, this video helped me figured it out what was the problem with my garage door, plus made me feel so proud of myself for fixing something I was about to call someone and pay to do it

Faulty wires was my issue. Thank you for this! We’re in a townhouse so the constant reject of the door was driving us insane, and my neighbors too I’m sure...

working fine now. thanks, you saved me time and money. cheers.

Thank you Mike. I had exactly the same problem you're describing with my garage door opener and I followed your instructions and I was able to fix it. Thanks a lot!

Mike, thank you so much! After watching your video I was able to figure out that my garage door would not close because there was stuff blocking the sensor! So simple but when you don’t, we’ll you just don’t know 😂

You’re a lifesaver sir! I was about to go nuts tryna figure out what’s wrong when nothing was blocking the sensors😆

Thank you so much!! My sensor was flashing and I simply moved it a tad and it works!!

Your video saved me...garage door wouldn’t go down after I took out the trash tonight and I was panicking! The sensors just needed to be cleaned. Many many thanks!

Thank you! This is exactly what was happening to me and I fixed it myself by following all your steps! Just needed to clean and realign the sensors. I'm so stoked!

Learn something new everyday. Video was perfect and right to the point.

Brilliant guidance -- this was the very issue and it was fixed readily by a simple readjustment! Am housesitting for a friend who's out of the country and was panicking. Free and clear!!!

Thank you so much for this video!! We were able to call a repair person and this was our last ditch attempt to try and do it ourselves to save $! This worked!!!!! Our sensors weren’t aligned and just needed to be readjusted. THANK YOU!

Wooowww, I had this problem for 2 years or more. We had to get out of the car and close it manually with the external control and sometimes the door was going back making us get mad and waste time, I replaced the rollers, greased everything and today I looked for another alternative and found your video. I just adjusted the sensor to have a solid green light and the problem was fixed. Thanks a lot.

Thank you!!! Thought the sensors were working fine because both lights were on until I watched this video - didn't realize a slight blinking of the light would be the cause. Such a simple fix!!

This video just saved me from having to call someone to fix my issue! A tiny twig was stuck in a cobweb over one of the sensors. Thank you!

Thank you for kindly providing this helpful information. I know a retired woman who was talked into replacing her sensors without the “expert” doing any troubleshooting first.

Awesome, thank you for this tip! My garage door kept going all the way down then suddenly reversing! I retargeted the sensor and it's been working well now.

My garage-door-opener issue appeared to be the sunlight that was mentioned near the end of the video. Very appreciated.

Thank you sooo much. This fixed it and saved me a $60 service charge and who knows how much more if I had not found your video and cancelled the service call! Keep up the good tips!

Mike, I'll echo all these same sentiments. You are amazing! Your simple, step-by-step instructions with video demonstration was perfect. This could have been our garage! I fixed a nagging problem in minutes. Thank you so much!!! Deb

Thank you I thought I was gonna have to call the professional fix it right up. It took me less than five minutes.

Thank you, OmGoodness I just bought a house & didn’t know even where to begin to fix this. The sensors were just dirty & all is now fixed! 😁

mike, seriously, thank you so much. this simple task, simple thing, just completely went over my head, this video not only fixed my garage door it also helped me realize i need to be more thorough when inspecting things. preciate it man!

I clicked on this video because it was the first one recommended, and I was prepared to watch several before fixing my garage door problem. However, “one click, that’s it!” 😆 Problem solved! Thank you very much!!!

You are a good sent. I can't thank you enough for helping me troubleshoot my garage door issues. That's exactly the problem I had. As soon as I adjusted the sensor the green light became solid and I was able to close and open the door. Thank you 🙏

Thanks a bunch! We're moving, and somebody put a box where it blocked the sensors from seeing each other. I thought my husband would be impressed. He wasn't. I take that as a sign that his confidence in me exceeds my own.

My garage door failed in the manner you showed me on your video. I checked one sensor that had a bright orange non-flickering light. Because of your advice, I knew that was the power sensor and that it was working correctly. I checked the second sensor and that sensor had a dim green bulb. I cleaned both sensor lenses with Windex. I adjusted the wing-nut on the sensor with the dim green bulb until that bulb turned on and remained bright green. The door closes perfectly. Thank you for your help.

Mike Thanks for the video. After watching I successfully fixed my garage door. The problem was exactly as you described in the video. One of the sensor was not aligned. The wing nut was broken. I put some tape around the sensor. The door now close perfectly. You now have a new subscriber. Thanks again, keep up the great work and keep safe.

Wow! So glad I found your video. I was just quoted $180 to come out and troubleshoot for the 1st 30 mins. I'm going to go home and try this after work and see if it solves the problem. I am so tired of having to pull the car out, go back inside to close the door, then exit thru the side door every day. Wish me luck!

Thank you sir after two months of flickering and trying to figure it out, I looked at your video once, and the problem solved. The Mrs. will be so happy it was happening on her side😅 Thanks again.

I was about to rewire everything. Glad I thought that was a bit much and sought for a better solution!. Thank you Sir!🙏🏾

Hey Mike, Thanks a bunch. Sometimes we take the hardest and most expensive roads to find out the simplest of corrections saved time and $$$$$! Cleaned the sensors, and garage doors working and closed the book for now on a new opener which was not needed.

Mike, you are a life saver! Your video showed me how to fix my problem in less than 2 minutes. Thanks so much!

Very good, simple and straight forward solution. It worked for me, quick clean up on the lens, some adjustments and the light came strong.

I literally just bumped my sensor with my trash can and my door wouldnt go down. I nearly fainted. Then calmed myself and did a youtube search. 1 minute into your video I walked over and adjusted the sensor and now the door is working again lol. That would have been a $150 service call. Thank you soooo much for this video!!

Wow! I had this exact same issue. I moved both my sensors up just an inch so they were aligned and that made it work. Thank you soooo much.

Thank you so much for this video! In my case, it was the sun that was interrupting the beam. It was striking directly against the emitter (orange light side). It has worked fine since we moved in and suddenly yesterday just started reporting "beam obstruction" or "faulty wiring". I checked all the wiring and even pulled the switch off the wall. Nothing changed. But when you mentioned the sunlight as a cause, I rewired everything and it is working just fine, as expected, because there is no sun on the sensor. It would work to open, just not to close, unless I held the button down, which I guess overrides the sensor input allowing you to force the door to close. You may want to list that as a potential cause on screen in the beginning or as text on the screen as well. That is for sure my cause! Thanks again!!! Never would have guessed since the door is not usually open at that time of day. That probably explains why it "stutters" during the day, as well. The sensor gets direct sunlight in the afternoons.

Thanks, Mike. That was sooooo easy to fix. The culprit was a lawn trimmer blocking one of the sensors. I can be such a dumb ass. Thanks for the help. My wife thinks I spent a couple hours fixing it. We’ll keep that between us. HNY! TR

Thank you so much for explaining what each side does. Mine would start to close and then stop. After watching this video I found a loose wire and problem was solved. Thank you so much!!! 👍

Sun was my hypothesis, but I've also had issues with the door after dark as well so I'll go check the alignment next...thank you sir!

This video just saved me the cost of a service call, thank you!

Excellent tip Mike, I will be checking the sensor more closely. Thank you for the video.

Thank you for a great tutorial, I found a nick in the cable going to the green sensor, cleared respliced , clean the lens, works perfectly no more blinks

The sensors not being aligned was exactly the problem. Thank you for the fix!!!!! Perfect.

Hi Mike, this really helped me fix my garage door that was bugging me for a while! I really appreciate it.

Thanks a lot for this video. It got me to check the sensors and I noticed a lot of spiderwebs in front of one of them. I cleared away the webs and sure enough, it is now functioning beautifully.🤗👍

Thank you so much!! My issue is what you had mentioned towards the end of the video; the wiring! I just had to maneuver it a certain way and it fixed the issue!!

Wow!!!! My garage door's vibration going up and down caused the wing nut to loosen!!! You're great!!!

Thank you so much!!! My dad isn’t home so when the garage door wouldn’t closed I freaked out. It was exactly like this situation and it worked!!

Wonderful!! Information like this helps those of us who aren't savvy when it comes to repairs and not wanting to spend hundreds of dollars for a tech to come out. Thank you!!

Thank you! Just had a new Chamberlain installed and your comment about the sun blinding the sensor solved the problem. I waited a half hour for sun to move and sure enough, sensor was in the shade and the door went down without a problem.

Worked and took 1 minute to fix after a year of it not working! Thank you so much for the help

Thank you so much. This is exactly what I needed. My garage for months was acting weird. I readjust the sensor amd it worked like a charm

THANK YOU!!! Within 5 minutes of watching this video my garage door is working perfectly again.

This is exactly the video I was looking for to solve my garage door problem. Thank you very much!

Wow, this was great and well explained. I figured I might have two issues, one of which was the "blinking" (inconsistent) receiver light. I determined that it was not a misalignment as you smartly gave as the likely issue folks have, but a loose power wire that when I giggled it on the this sensor box, the light went steady. The door now works normally. While I may have to repair the wire/sensor,.....your video was instrumental in me going to the "target" issue, and finding the answer. Thanks!!

Thank you very much for a most instructive and concise video! I was able to fix my reverse issue in about 5 minutes after watching! 🙂🙂🙂🙂
