My opener is a lift master m# 1345. The door will not open or close with both remotes or wired switch. The opener constantly is clicking and the lightblinks constantly. It will only stop when I pull the plug from the outlet. Is this a logic board issue?

Detach the garage door by pulling that piece of rope by the railing. And then use your remote or wired switch to open. If it dont I assumed that is your logic board.

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 have an old sears Digital Control opener, for mine to work I had to get the 355 LM 315MHZ receiver and a 85 LM transformer to plug into the receiver, and a remote, I got the small one Liftmaster 371 LM , and make sure you have an AC plug in close to plug your transformer in.

Is it the same garage door, if not it might be a different model & code#, that might not work? I purchased a single button LiftMaster, that works on ony one of my three garage doors. All three doors are Sears, two are the same (model /code) & one is different (model/code), al-though the three look the same. Two codes are the same and one is different! Two 3 button remotes work two dooors, but won't work on the third door. Other than that, you might want to call LiftMaster. Good luck, Mario...

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

I have a 15 year old Liftmaster opener and the remotes stopped activating the opener. I bought 535LM receiver and wired it per the directions and it works just fine. I mounted it by the door, so now i have two places with "push button control" and the receiver is closer to the outside wall which improves the reception from my HomeLink car transmitter. Be sure to by the transformer (they should package it with the receiver as most installations require the transformer).

At least you have a connection, check the antenna (the wire that hangs down from the opener) perhaps the signal can't reach the unit because the antenna is not hanging down?

I cannot get either one of my openers to work. I have contacted the seller several times and none of their suggestions helped. I contacted five local gate opener dealers and none of them has any experience with ALEKO. I contacted ALEKO to ask the name of anyone local who will help me and they did not even reply. From my experience you may draw your ownconclusions.JNMPE@aol.com

Page 24, of the manual explains the different features. I have my light shut off, with the exception of when the door is open or closed, then it shuts off in 3 mins. Never on unless I force it on. Hope this helps. http://www.liftmaster.com/CatalogResourcesV3/en-us/shared/files/tucmanuals/114A4565.pdf

First you need to make sure the remote will work with the opener. I found that not all will work. Then there should be a colored button on the back of the opener. Press that then press your remote button. Then press the remote again and the door should move. Once I had the right remote that's all it took.

Hey Marc-This wouldn't be the correct remote for you. Do you have a working remote for your opener? Thanks...Matty

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.

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.

If you have a liftmaster or chamberlain with the plastic gear drive take a look at it and see if it is stripped. Sometimes when the chain is tightened it puts too much pressure on the big gear and concaves it. Thus the door might start but the gear would slip and not go all the way up. The other thing to check is the up power adjustment.

I am not familiar with your opener, but The LiftMaster 850 basically just makes a contact, the same as a doorbell type switch. If you have two wires that lead to a wall mounted switch, it's almost a certainty it will work. If you have a wiring diagram inside your current opener it may help you find a voltage source to operate the LiftMaster. If you have terminals for the doorbell switch wires on the outside of the opener, just follow the wires to the inside of your opener. This will tell you what wires need to make contact to operate your opener. Disconnect and run those two wires to the Liftmaster. Very easy.

yes. I have 2 openers side by side and I had the same issue. I called lift master several times. Finally I got someone that was knowledgable enough to help me. he said that if the openers are too close together this problem occurs. He suggested moving one so that they are about 18" apart. The other option is to turn off the sensor on one.
