LiftMaster 8365: Door Won't Close and Lights Blink.
ฝัง
- เผยแพร่เมื่อ 18 มิ.ย. 2020
- Diagnostic code on the opener is 1 blink on the Up arrow, and 2 blinks on the Down arrow. This means there is an issue with the safety sensor wiring.
So just recently one of our garage door openers encountered a problem where you hit the button to close the door, but instead of closing, the lights just blink. This is usually an issue with the safety sensors near the bottom of the track. If these sensors are either obstructed, or not working, the door will not close normally, but will open fine. The opener lights will also blink 10 times if there is a safety sensor issue. In the interim, you can force-close the door by pressing and holding either the wall button, or the down arrow on the opener until it fully closes, but the remotes will not work.
Wiring issues can sometimes be tough to trace, but I think I did find the issue that ours was having. - แนวปฏิบัติและการใช้ชีวิต
Inspired me to check wires! 3 years later still helping people out. Thank you!!!!
Aware that my son usually checks TH-cam when he has something that needs fixing, when my garage door quit closing I checked and found this video. I watched the whole video, and before heading to the garage where I immediately found that the problem was one of the sensors on the lower door. It had apparently been bumped out of position. A very quick fix. So thankful that a repairman wasn't necessary.
Always nice when things can be done yourself!
I’ve learned sometimes in life patience is a virtue . I was watching your video trying to understand how your video applies and it did I just had to watch it understand and apply practical common sense thank you
Thanks for watching! Yeah some think I should have gone faster, but a lot of times, details are important!
Extremely helpful! I had opened the cover to program another remote and all of a sudden it won’t shut. The error codes shown indicated an error code of 1 up and 1 down. Come to find out, a wire got knocked out just enough from the unit up top. The light trick (turn on the light and look for the other lights) was so helpful as was the error codes! Also, comments from the vid were useful! Thanks so much!!!
Hey great! Glad it helped ay fix the issue! Hope it stays good for a while now!
Thanks for the tip! I troubleshot and wiped the sensors clean, only to find a single spider web strand impeding the progress downward. Those sensors are mighty sensitive!
Oh sure thing! Yeah it's amazing just how sensitive some things can me, as ya said!
Same here
Jus with the first 53 seconds I fixed the problem. Thanks!!
Hey no problem!
Video was helpful my issue was the red cable was not twisted with other cable it became unwound not making contact twisted them back together reinserted and works like a charm thankz…😊
Hey nice work! Glad it's fixed!
Wires uh. I'll check them out. Thanks Amigo.
My door is acting like there is a blocking between the sensors but there is none. Back of my lift next to remote programming button, i have a yellow light blinking that blinks in 4 blink cycles.

My problem was resolved in the same manner
Great video you just solved my problem I had.. 1 of my sensors was off target light not on
Intermittent connections are a pain! Just when you think it's fixed, it messes up again. Seems like it is up at the motor side from the way it cleared up as you moved the sensor wires.
Not a bad idea to get that staple out of the sheathing down at the sensor end! Perhaps a dab of silicone will seal the hole up, and not be too noticeable.
Yeah it could have been that. I told Jay that before I started recording the video, I had done some stuff above the powerhead, and it still had the error code. Maybe the wires needed time to relax back out or something, and I recorded the video just in time before it fixed itself. Really hard to tell. But at
the same time, I am glad I fixed that staple, and moved those wire nuts. Definitely could have avoided a future problem right there too.
Well hopefully it keeps on working as it should. Yep I like to fix problems like that before they cause trouble later on. Usually happens at the worst possible moment.
Thanks so much!!!! I wiggled the wires attached to the sensor and the lights on the sensors came on. Now it's working again. Thanks so much for the very helpful video!!!
Hey no problem. Glad it helped ya!
Same here! Worked like magic! Thought I was going to have to hire someone and instead, your video saved the day!😉
Same here, wiggling wires on unit fixed the issue. But not sure why it stopped working all of sudden.
Thank you!!! Big help
Hey no problem!
This happened to my chamberlain hd600d when my mom was backing the car out I heard a weird noise and then I notice the sensor lights were off and thought the car triggered the sensors and that’s why it did not close Thanks!
Sure thing! It seems most close issues are related to the sensors.
Tried it all , nothing happening . Tried all your techniques till I was blue in the face . After doing further research I found that my problem was my WEB CAM I had in driveway interfered with my sensors . I disconnected the web cam and works like new .
Right church, wrong pew. After you looked at the sensors the first time, when you went back up on the ladder, the lights were flashing. You then inspected the wiring up there, and the error code went away. You have officially isolated the problem. Fixing the staple wasn't a bad idea, but I don't think it was the cause of the issue.
Either the tight bends of the wire above the opener was the culprit, or where the wires plug in developed some sort of dirty connection. Wiggling everything made it work. My dad had an acronym for that. FATTD. I'll email you with what it means since it's not safe to post here.
Ah, so then I'll just say 10 Hail Mary's before tonight!
Before I made the video, I did play around with the wires a bit by the opener. I did take them out, give them a cleaning, and then put them back in. Same thing. It could have been those tight bends, but I did look at I believe two of them before recording, the code was still there. Maybe it needed time to relax back out, not sure. As far as I could see, those wires that were just above where the hangers intersected looked okay. I remember being totally sure that they didn't get pinched when you and I were reassembling everything. I could have another look at them again to be absolutely sure. This is one of the issues with electrical problems. Making sure it doesn't come back.
With some spare wire long enough to span the length of the original, and a VOM on the ohms scale, having one person wiggling the wire and another reading the meter, would verify the failure point. If no trouble is found, then it's where the connector that goes into the opener is.
@@jaykay18 Makes sense. If this issue does return, I'll look more closely at those spots above the opener; the tight bends and above the hangers again.
I can tell you one thing. This sure felt like a classic Octember moment!
I know the feeling all too well!
Thank you! I had somehow knocked the wire out just enough up top when opening the side. It was sooo bizarre as it shut just prior fine. Thanks for this conversation!!!
Just a tip for you with the sensors. They both have a light. The sending sensor has the yellow light and it sends the invisible beam to the receiving sensor with the green light. The yellow light should always be on, but the green light on the receiving sensor will only be on when the sensors are aligned and not obstructed. If one or both lights don't turn on, then it's most likely a wire issue or defective sensor. You just check the code from the opener at that point. It could also be sunlight in certain situations
Your comment is Extremely helpful. The yellow and green are both on, but the still will not close. The wiring looks okay as far as the see. May have to call a tech
@@carolync9408same here. Not sure what the problem is
Thank you!
You are spot on with the sunlight effect. That was my problem, it was that certain time of the day where the sun is glaring straight at my green sensor, so I just changed the angle a bit and voila!
It works.
How do you tell what model you have? And where do you get the manual from? We never got one when we bought our house.
There might be some kind of model label behind one of the light lenses that could help.
I agree with him. It's just a garage, not a living room. The wires shouldn't be in the wall and the ceiling
Exactly right!
😂
Thank you so much
Anytime!
I have the same garage door opener but inside the box when I push the button where the battery is stored neither up or down works,what could be the issue
Hmm unsure. I don't have a battery model.
You touched a wire and said that looks ok let me try it now and it worked.. I didn’t see you do anything. Maybe i missed it
Yeah might have been that wire, maybe something was pinched.
You got a like from me.
Thanks for watching!
I had this very same problem. Garage door opener installed about 3 months ago and functioned fine.. all of a sudden lights on both sensors went out. same arrows flashing on the head unit, got a sensor error on the myQ app on my phone. The wired button in the garage would close the door if you held the button down. Down near my sensors on the garage, one of the wires was shorted out w a staple that was placed to secure it.. oddly enough, before i removed the staple, both sensors were not lighting up.. one should be orange, one should be green if wired properly. It was not a malallignment problem w the sensors. After i removed the staple, problem solved. If there is a malallignment problem or something obstructing the sensors, it seems that the green one will blink, provided that they are wired correctly and functioning.
I checked all the wires on the head unit/opener, which were all connected and secure, so i went to the sensors next.
Yeah sometimes these guys staple these things too tight!
My garage door won’t close. When you press the down button the light flashes 12 times. Still no closing, even if you hold the down button continuously . I have replaced the sensors and when the light is on there are no lights on the sensors. An help will be greatly appreciated thanks, Dave
Hmm might be a different issue, see if you can find your owner's manual to show what 12 blinks are. See if your opener has up and down arrows like this one does.
Having the same exact issue. Did you figure it out and if so what was it ? Would really appreciate the help.
@@Djtrixer1 had the same installer come back and fix it again no sure what was wrong this time. It’s always something.
4 up 6 down
Thus us what happening to mine right now.
Mine is only not closing when using my car remote control.

I honestly despise this! This is why I kept my vintage Sears Craftsman.
6:59 Oh geez! That's very stupid and very dangerous!
Yeah electrical problems can be tough to spot. But I think that staple could be one of the issues. I almost laughed when I spotted it.
@@Sharkie626
That electrical problem is a red flag to me. Also, fire inspectors would agree with me on that.
That,$ funny / I did the same thing / n I just touch the wires/ n it work my remote control 😁 n I said the same work that,s weird 😅

Dude, your camera goes everywhere so fast it makes me dizzy. Slooooowwww down when panning your camera. Thank you.
Thanks for that. One of the things I tend to do is cover a lot in a short time, which I guess can cause said issues. Some videos are better than others, but I guess I can take note. Thanks for watching!

Oopp
spin around a bit more, please. I almost saw something you were talking about.
