I have a liftmaster garage door opener model #1255R, one light out front and two single remotes #971LM, currently the logic board in it is a 41A5021-1F. The remotes will not open the door from outside but will close them from outside. The remotes will work fine up and down when inside the garage. The opener worked fine up to about two weeks ago. Will an updated logic board solve this problem? We have no LED bulbs anywhere in the garage everything is the same.

Hopefully you were smart enough to check the batteries first, DUH! Change out the board I had the same issues.

I had a similar problem with my liftmaster so I called Chamberlain customer service. After trying a few troubleshooting procedures he diagnosed that it was probably the logic board. Their price was ~$95.00 but he suggested I try Amazon. I have had the new board installed for a couple of months now and can open and close my door from at least three houses away. The board was easy to install but take care to unplug the opener when working on it and use the instructions included with the new board for programming. You should have no problem. Best wishes on your project!

my remotes were acting strange and replacing the logic board fixed all problems.

Yes, it sounds like you are in need of a new logic board. It's not your batteries because its working in your garage. Suggestion, if your unit is more than 10 years old, I recommend just spending double the money you would spend on a logic board and replace the unit in whole. Once the logic board is in need of replacing, the other parts tend to want to give up as well.

Hey Ray,I happen to be a garage door technician. First of all I would recommend you to buy new 2032 batteries for the remotes and try that (you might need to re-program them once you put in new batteries). Make sure you put them in the correct way with the negative side down. If that doesn't work then it's definitely a logic board issue. If you replace the logic board, make sure you unplug the unit first. After you finish puttingin the new logic board you'll need to program all remotes and keypad. I hope this helps you

No, the opener will still not function due to the lack of light sensor. But you can buy replacements at Lowes on the cheap

If all 3 of these are true, I would consider changing the receiver logic board:(1) The hardwired button in the garage operates the door opener correctly.(2) Neither the remote in the car, nor the remote on the outside of the garage work.(3) The remote in the car has been re-programmed (again) to match the opener - but it still doesn't work.I think the receiver board is sometimes damaged by nearby lightning strikes.Actually, I purchased a new remote for the car first and tried that. However, when that didn't work, I bought the receiver board. Replacing the receiver board solved the problem!Good luck!

I wish I could give you an answer, but I no longer have the packaging my liftmaster came in. I can say that I matched the numbers on my original remote with what liftmaster said would be complatable with their remote. I have had no problems with mine in the 6 months we have owned it. Best I can say is try to match your model with the one liftmaster says is compatible. Sorry couldn't be more help. Best of luck to you.

I believe there are two options for part 41AC050. There is no light on the panel of our garage door opener, so I chose the part that has no light. You should look for one that has light instead.

That's why I replaced mine. Lightning damaged the unit, and according to the manual if resetting it doesn't fix the problem, then the next step was to replace the logic board. Mine blink 5 times as well. Once I replaced it with a new board it worked (all wireless remotes will need to be reprogrammed to work with the new board, follow the manual on how to do that.) I can't say for sure if it will fix yours, best of luck.

I would find the model number of your door opener on the ceiling. It may be on the surface where the light bulb is. Call 365 garage doors (860) 281-8141 or https://porch.com/hartford-ct/garage-door-specialists/365-garage-door-parts-garage-door-professional/ppThey will be able to tell you which one to buy. I bought one for a 37 year old door opener and it works great. Absolutely love it. Bought it because I was locked one day in a horrible thunder storm and decided that wasn't going to happen again. They sell them on Amazon.

This switch must be programmed to the associated remote control device. Perhaps door opener remote control could also be used to also program this switch. I would contact LiftMaster for advice, since there are different generations of remote controls and associated devices. All of their products do not play together. BTW, I have used this switch successfully for a couple of years to control lights in an outbuilding from within the house.

I believe it may depend on which model opener you have, but for my opener the light does go out after awhile once the garage door switch is activated. This is true for not only the wall switch but also the remote.

Aha! That's what happened to us with an earlier model (PIR 720 RN). We installed it in our garage years ago. I don't remember its history, but in recent years it has been controlling a 100-watt incandescent bulb that burned out a few weeks ago. When I replaced the bulb, the motion sensor would not work (it failed with circuit closed, just as if it were not here).

John, I believe the yellow light flickering indicates that the garage door controller is receiving an RF signal. It could be from some other device in your garage. It could be from one of your remote door openers (are they all accounted for?) It could also be from a device belonging to one of your neighbors, transmitting on the same frequency as your garage door opener. My first try would be to unplug the garage door opener. After a minute, plug it back in. The large light bulb (not the flickering LED) should blink several times, and the controller board inside the door opener unit will reset. Hopefully, this will solve the mystery of the door opening by itself. Good luck.

My opener has a front light on and it still works after replacing the board. I believe what they're saying if that you will loose the light at the back if you use this replacement board, if it fits at all. Have a look at the back of the unit first, you should be able to read the logic board part number.

I have two of these. One on each side of my garage door and they do go off randomly at night. They come on together no problem but then at random times one or the other will go off and then turn itself back on just as randomly. So far I have not noticed that they both go off at the same time but I don't stand there and watch all night either. When I first put them in and flipped the light switch on at night they blinked several times but then came on and stayed on, but now I have this random on and off thing going on with them. Anyone else have this happen?

The Liftmaster 3265-267 is no longer available. If you order the Liftmaster 3265-267 on Amazon, you will get the Liftmaster 8365-267. Your wall control and remotes from the 1265LM will not work with the 8365-267. The 8365-267 comes with its own wall control and two remotes. You do not receive a new T-rail. You just receive the garage door opener with its wall control and two remotes. I replaced a 1260LM. I had no problems dimensionally. My T-rail dimensionally connected to the new opener without any problems. In otherwords, the attachment holes for the T-rail on the 8365-267 were in the same location as they were for the 1260LM. The 8365-267 is working fine for me in my application. The old photosensors at the base of the garage door for the 1260LM are working with the 8365-267. If you want absolute confirmation, why don't you submit a question to the vendor 365GarageDoorParts. They are very responsive.

Make sure the battery is not in backwards. If that is not the problem then you might need a new remote. Try contacting chamberlain customer support and explain the issue. If they can't get it to work then they should send a new remote since the opener is still under warranty.

Recommend calling liftmaster direct for best answer. Basically the older models worked off analog and the new models are purely digital. The 880LM is a digital upgrade and I use it as a second controller in my garage that has two entry doors. The 888LM upgrades older liftmasters to the increased features on the new models...I.e. adds a motion sensor for turning on lights and adds capability to auto close the door if you don't hit the hold button. The Amazon descriptions got me confused, but the liftmaster service desk got me right on track. I have 3 openers...two are the old technology and the newest is the digital opener that i used the 880LM on. I upgraded one of my older openers with the 888LM.

It's very likely the opener. You may want to check the reflector/safety mechanism if there is one, and make sure it's aligned properly. To make sure it's not the remote you could try removing the batteries and not using it for some time, instead using (assuming you have one) they key pad.
