TROUBLESHOOTING, REPAIRING AND PROGRAMMING GARAGE DOOR OPENER THATS NOT WORKING 

Thank you so much for sharing your video. I lost one of my garage remote controller and got a new one an Amazon for only about $21. It wasn’t the original. By following your steps to program the 2 new remote controller worked right away. Your video teaching was a blessing in the sky. Keep up the good work and thank you RU-vid for giving others the opportunity to share and others to follow. By the anyone out there, if you are replacing a remote controller don’t buy the original, too expensive. I got it on Amazon for only about $21 and worked… Thank You…

Thanks! I was getting ready to replace my 7 year old Liftmaster 8500 when I found your video. Turns out my 888LM was faulty so I replaced with the new 889LM… bingo. Thanks again.

Very helpful and clear video. Thanks for sharing your knowledge.

Nice info .. what a PITA especially if the openers are built into your cars. Never mind the deleting and redoing your apps.

Thank You sharing your knowledge I needed it.

Good Job!!! I've been trying to program a third controller and ended up "Un-programming" my other two... Don't ask how. But I had the instruction from the garage door operator. did it several times per the letter.... nothing! just watch yours and thought I would give it a try. when I first went to my wall mount controller the red light wouldn't even come on... I thought I may have something more then just programming issue..... so I cycled the door one time from the wall mount and tried the learn button again....this time it came on and stayed on... got my other controllers and had all three done in about one minute.... thanks!

the wall controller supplied with older 8500 op have 2 caps inside that were suppose to be over 100,000 cycle caps , but failed after just a few years ....that's why they honor the warranty and send a 889 lm as a replacement.....good company

The instructions are pretty clear and easy. I installed mine, but the red+yellow won't stop blinking, and it's also accompanied by a beeping noise. Could the backup battery be at fault?

nice video. I have the same issue with my smart panel. The light is flashing orange and it doesn't respond to any of the button i pressed whether its lock or learn. Does it need to be replaced?

Thank you for making this!

My liftmaster wall pad keeps beeping nonstop. How did you contact them? Hoping mine is still under warranty

my wall mount panel isn't working but everything else is still working. my app says to call a garage door opener company over 30 minutes away. looks like I'll be reaching out to the manufacturer.

Yes i changed both capacitors and its working. I see as soon as i open it that one capacitor is bulging. So i order amazon 5pc with 15 $ which is. A rip off and i change them both

If a red light above my learn button is blinking red intermittently on my wall mounted door control and making some intermittent buzz noises, what does that mean? I can detach the door control from the wall and disconnect the wires. I can touch and hold the wires together and the door operates. So despite the obvious solution of replacing my door control, is it possible to rule out if the wires were just not wrapped around the screws well or sufficiently? I'm trying to rule out correcting the problem within the door control before just buying a new one for $45.00. Is there a button to hold to clear out memory or commands given?

My issue is that my wall pad started blinking both lights and beeping. remotes don't work, keypad doesn't work. Do I need to replace my wall pad?

thx a lot man it solved my prob

Liftmaster has a recall on the older units, just called them after my device failed and they will be sending me a new on for free!

Beautiful Mercedes…my wall control is flashing and not working, I can open and close the garage door with the remote n my car, I cut the power off and nothing…what do you recon?

When you hold the "learn" button for a few seconds you actually just erased all old remotes. This is good if you lost a remote or acquired a new property with an 8500. To program remote only just press the learn do not hold it down unless you want to re program all remotes!

... holding the learn button for 10 seconds resets the wall controller. You need to push the learn button twice to get to the learn mode. ( no need to hold for 3 seconds)

I have the exact same problem with the exact same unit I purchased in 2015. Can you tell me who you contacted to get a replacement part

So you had a bad wall mount controller? Did they send it at no charge?

My wall unit control still flashing and do not respond,what can cause this?

My garage door goes down as programmed, but the second it makes contact with the ground it goes back up. How do I correct this problem?

Great video but what if the control panel lights continue to blink???

Question: if someone were to break into your vehicles, could they just press those buttons and gain access into your garage? And how many ppl actually keep the interior door which leads from their garage into their home, Locked? Now the Bad Guys have entered your house.🤷🏻‍♂️😳

What are "bu uns"? You said to press bu uns.

What's a buhtnz? Ther are called buttons. Say it again. I know you can. BUTTONS! LOL!

What is going on?!? This is the 5th video that someone says "bu un". It's a button it has 2 T's in it. Are we all turning into valley chicks?
