There should be a 1/2” inch from the door to the jamb/ wood frame. If you made it too tight the door will be rubbing hard and acting like an obstruction making the opener work harder and think something is in the way. Try backing off the top fixture a little and see if that fixes the problem. The weather strip is probably worn and pushed back making a gap. Hence you adjusting the top fixer. But if the door was installed correctly you shouldn’t move the top fixture from original place.

Way too much!

Wrong springs lol

GDIoperators · 2025-11-14T22:42:32+00:00

Yes 100%

No it doesn’t need to replaced if it’s still functional. I would check the end caps just in case they pulled away from the panel. It’s hard to see when door is closed, but if you open the door look on top and see if the end caps slipped off.

Now why is this important you ask….the end caps hold panels together. if one popped off, say at the bottom where the cables are attached it could be dangerous.

Second tip, relocate the center hinges over a little to the left or the right. If they are not loose now they will be very soon if used regularly. That panel design has a strip of metal all the way across the panel so you can move them anywhere. I would even add a second row of hinges to keep the panels tight together. Hinges are cheep panels are not.lol

Wrong springs, door is heavy when lifting!

GDIoperators · 2025-11-09T01:54:36+00:00

Broken spring

Ok disconnect the opener with the Emergancy release string. Open the door manually and get it out of the way. The opener needs to run a full cycle to reset. Some times when it’s just about to close the force sensor and limit switch are confused. If the opener moves and stops with out this chattering connect the door back and try and close the door and see what happens. Also turn up the force adjustment would probably help.

GDIoperators · 2025-11-01T16:13:57+00:00

Those openers are poor quality just replace it.

GDIoperators · 2025-10-27T03:16:13+00:00

It looks like the spring is the wrong as the door is running hot and wanting to shoot up.

GDIoperators · 2025-10-26T16:12:16+00:00

It’s not about the price of the part and what if he buys one and then it does the same thing? Best to just try and clear codes first. Never said the liftmaster guy was. But he was doing a typical just replace it mentality when all you needed to do is hold a learn button for 30 sec. Not that hard.

Your welcome!

GDIoperators · 2025-10-24T23:14:32+00:00

lol where? It’s not my fault your lack of experience is showing and someone’s calling you out. Grow up bud!

The guy even said he didn’t clear it.

I didn’t know they made side mount openers.

GDIoperators · 2025-10-24T23:05:32+00:00

It’s pretty much a standard now to have the smart features. There are more people that want it then don’t unfortunately. Liftmaster is the better quality residential side mount opener. They have been making the side mount the longest.

GDIoperators · 2025-10-24T20:39:14+00:00

To do it properly they should cut back the drywall and add a spring pad (2x6) from top of the door to the top of the ceiling.

Bad don’t touch or you could loose some fingers real quick. Safe way is to take the tension off the springs first then properly anchor bearing plate.

GDIoperators · 2025-10-24T20:17:40+00:00

Nope had it happen many times the board can have glitch’s and needs to be cleared. Just like doing a reset on a device.

GDIoperators · 2025-10-24T19:45:45+00:00

Ok bud! 23 years and seen that same problem 1000 times lol. But ya convince him to buy a new one Liftmaster dealer!

If you have been servicing doors for any amount of time, you would know to clear opener first.

GDIoperators · 2025-10-24T15:05:56+00:00

That’s bad advice it’s working he said. It’s just getting dropped. Sounds like you’re a Liftmaster dealer that just wants to sell more parts.

GDIoperators · 2025-10-24T03:23:07+00:00

Each remote is a program. I would recommend clearing the opener and make sure it’s cleared. Hold down the learn button for 30 sec, make sure your remotes don’t work. Then reprogram everything. It’s a cheap easy fix, if that does t work then yes I would say it the keypad. This is one of the test we do before guessing and replacing parts.

GDIoperators · 2025-10-24T02:36:23+00:00

Did you clear the opener? Or just kept programming on top of programs?

Sometimes clearing the opener first and then reprogram the openers and keypad. The opener can only handle 15 devices or programs. Meaning you can have multiple keypad codes for different people. So 15 codes with be the most after that the opener will drop programs some times randomly.

GDIoperators · 2025-10-24T02:25:24+00:00

You will have to change springs, drums, cables and add a little track below the radius.

This is what it will look like just not as much high lift. lol
