My problem is the emergency latch with the red handle. I cannot pull it anymore it’s real loose. How do I fix that? So if an emergency I can still open the gate.
Keith Sanderson, sorry to hear about the problems with your gate operator. It sounds like you are having issues with your remotes not working properly? The LiftMaster LA400/412/500 have built-in radio receivers, that to my understanding do not have the ability to change frequency. If you are having issues with the range of the remotes, you may try relocating or raising your antenna higher in the air. Things like metal and other electronics can cause interference. A new radio receiver and/or transmitter may also be suggested, one(s) that operate on a different frequency that you are currently using.
I changed battery on the lift master key pad model number 877 max, now the key pad doesn’t work, will you please let me know what should I do , thank you.
If you are using the 877MAX with a LiftMaster gate operator similar to the one shown in this video, you have to locate the Learn button inside of the gate operator control box. Press the Learn button on the main control board, and then press the Open button on the gate operator control board, then press the open button on the 877MAX.
The gate/fence panel should be able to move freely and easily without any assistance from the gate operator. Try turning the power off to the gate operator, use your key to release the arm actuator, and try moving the gate panel back and forth. It should move freely without binding. If you struggle moving your gate panel, your gate operator is going to struggle. This may be causing the error code you see. This could also be a problem with the Absolute Position Encoder, or APE. You can check the wiring on this piece to make sure it is all still intact, but most likely this piece needs to be replaced. The APE is located inside the actuator arm and diagnosis and repair should be done by a qualified gate technician.
@Bob Mosley, the error codes displayed should only be displayed as numbers, so I am not quite sure what is going on. Can you enter the Errors by pressing Open, Close, and Stop buttons at the same time?
My gate won't close. Just only little bit and open again. I've checked wires. System is 2 weeks old working fine until today. No error codes. Any suggestion? La500
That's weird that you wouldn't see an error code for this type of problem. Are you able to watch the main control board while the gate attempts to close? Perhaps the code is flashing only when in motion? Also, keep an eye out for any other lights, or LEDs, that might turn on when the gate stops and reverses.
If you are still not seeing the cause, I would start with looking at the gate panel itself. Turn the power off to the operator and manually release the actuator arm. Attempt to move the gate panel close and open; does it bind up at all or is it hard to move? May be an issue with the operator requiring to much force to have to move the gate panel.
A photo eye, or edge sensor, may also be causing the gate not to close. A photo eye can be triggered falsely if it has any built-up condensation, or dust on the lens.
Linda Craig, we would be happy to assist. Can you please let us know what model remote, and what model gate operator you are using? The remote model number should be on the back side, and the gate operator model number should be on a sticker on the outside of the control box. Photos are helpful.

What is the booster switch for

how do I change my security code? The previous owner is still accessing my property.
Did you figure out how to change code?
@@benjaminn12 no sir I haven't.
My gate won"t open and the code is showing 93 which means something is blocking the gate. But nothing is blocking the gate. what can I do?

Sorry you bought this piece of crap
