I have a Liftmaster LA 400 and I just replaced the batteries for the third time since I’ve had it. this time I continue to have a problem with this gate opener and I was hoping you might be able to put your finger on what the problem is. Today, when I went out to open the gate, I heard three beeps, and the gate would not move. I hit the reset button and still nothing. It was only when I pulled out the 20 amp fuse and put it back in that the gate would operate. But even then, when I pressed it a second time, I heard the three beeps and it wouldn’t operate until I pulled the fuse again. I replaced the fuse but it still does it. I put a multimeter on the transformer and it goes up to 24 and then bounces around but 24 seems to be the full trickle charge. Any tips would be really appreciated
@samswain7942 went great. Sync up the two units, set the open and close points, connected the approach sensor and the close sensor. Also, an entry keypad. Right afterwards someone un-bolted the gate and broke in. Need to install a security camera now.
good morning friend, a question bot to install a lifemaster 400 but no more I have the 4×4 post plus 3 hinges do you think that if it can be installed and the motor goes inside and the door opens from the inside, could you help me
Great videos...Question on the Cartel CP-4 automatic gate opener...I wired it just like you mentioned but It wont work...Are you familiar with the CP-4 and its wiring? Any ideas on what am I doing wrong.
That one is wired differently, I’ve done those many times also. You will wire the Red to the positive Power and Black for the negative Power on the bottom Connector. Then on the exit terminal you will wire the blue and white to those two terminals.
The photo sensor is there to sense a person or vehicle while driving through the gate so it doesn’t close on you. When you pass the sensor then it will do its timed delay of how long you set it at. You can set it from 1 second delay to I think 80 seconds. If you want the gate to open when you are approaching from the inside then you would install a buried exit loop. If you watch the video I explain each item and how they are hooked up to the unit.
I have a LA400 with error code 34, I read thru manual and can not get arm to retract. While the box was open, I did notice a yellow connector/cable is disconnected from left green cable holder inserted into assembly. I’m thinking this is something that needs more than a reconnect from me. We recently had a tornado so I can see where cables would become loose. Is there any easy way to determine which port is its home ? Thank you, Anna from Houston
Its repair turned into a fiasco. $1,300.00 to replace mother board, which I retained, its replacement failed a week later. Company reinserted original board and replaced another circuit. $1,400.00 total repair. They are convenient but expensive to maintain. Thank you
Good question. I’ve tried a lot of things. Depending on what kind of soil is under the drive way. This one already had a pipe. If it is dirt you can buy a fitting at home depot that you connect to a pipe and water hose and that works pretty good. If you have rock, then pretty much nothing works unless you want to pay a lot in rental equipment to bore it. In this case I just cut the asphalt or concrete with my Stihl concrete saw about a 1” strip and then repair it.
So I am having a problem we’re my exit wand doesn’t want to work, this unit also has an access control wired in. Can I hook up both access control and exit wand to the same exit lug?
Black and blue to exit terminal. yellow wire and white wire are negative and red is positive. Make sure you hook up your wires to the 24v power that is constant not to switch one as it won’t work

Why didn't you mount the arm to the lower bar?

Awesome. About to do a big dual gate project, doing some research before the big day.
How did this job end up going for you. I'm in the same boat

Photo sensor is on outside of the property . Is it to help close . ? How about if I want the gate to open when I am approaching it

I need part one-three
Very nice video ... thanks .... ??? my unit comes with 2 batteries ... can you show me how to install the 2 batteries with the cross connect... thanks
Great video, Have you ever install Maglock MG1300 to LA 400 control board? Can you show how to install them ?
Gl1 is far superior lock from Assa Abloy...I've installed several. Mag locks suck because if wire cut the magnet denergizes
Direct burial of cabtire? That's not proper cable thus code violation...at least here in Canada....needs to be mechanically protected in pipe.

Did you get that fixed?

What method do you use to run cable under drive

Im having same issue!!! Cartell CP-4 exit wand! Doesnt wanna work
@@kenanderson8387 did you just install it?
