Most likely your chain is not going to be your problem. When you pull the cover off of your SL 3000 there will be a little rectangle box on top. There is either one or 2 screws holding the lid down...loosen the screws and take the lid off. Inside there will be a long screw drive with 2 plastic nuts with teeth.At either end of the screw drive you will find a switch that one of the nuts should be resting on. (these are your limit switches that tell the motor when to stop) Run the gate open and closed...when you run it closed see if it is hitting one of the limit switches when it stops. (turn off the power) If so, hold back the plate keeping the nut in place and move the nut further away from the limit switch.(don't move it too far so that you don't slam the gate too hard into the catch post and hurt the post/gate/motor) Turn the power back on and run it again. Repete this untill the gate is stopping where you would like it too. e-mail me with any further questions

My Elite Sliding Opener is not closing. It hits the the end of the gate hard and retracts back?

The Limit nuts are out of adjustment. This can be caused by the chain jumping the sprocket, usually when something gets caught in the chain or it has not been adjusted. It can also be caused by a cracked limit nut. The limit switch and nuts are located at the top of the operator (under the cover) and has a lid held on by a single screw. Loosen the screw, and remove the lid.

elite-sliding-opener-not-closing-hits-3i3gptxgjc4ofcs21h1ecra2-1-3.jpg Inside you will see two cogs on a threaded shaft with slots cut into them. These slots are there so the lever will keep the nut from spins and allow it travel down the shaft as the shaft turns. The limit nuts eventually contact the limit switch, stopping motor. Look closely at the sides of the nut to make sure there are no cracks allowing the limit nut to spread open and slip on the threaded shaft. You may have to clean them to see it.

If the nuts are not cracked, simply press the bar holding the nuts in place back with a screwdriver and spin the nut towards the limit switch until the gate stops about one to one and a half inches away from the post. The gate stopping point can vary even more than one and a half inches on slopes so if it starts happening again, give it even more space.

Good luck

Myhouse gate

There is a switch in the housing that tells the controller if the gate is open or closed. The switch is bad or out of adjustment.

If you bump into the gate, the gate stops and it doesn't go back why?

Check in the control box for a safety sensitivity adjustment screw. It probably needs to be increased a bit. Or, it may have a switch for two settings. one for stopping and one for rebound. Hope this helps

My elite gate won't close. the charge ok led light is not on. checked everything and it's ok. switch limit switch on both sides works fine except when trying to close, it won't run.

If you disengage the motor does the gate slide easily? if not that could be the problem, most gate control boards have a sensor that detects the current drawn by the motor, if the gate hits an obstruction or is jammed the motor draws more current and the sensor stops the gate moving. It could also be a problem with the safety sensor, to check this locate the safety sensor input on the control panel and bridge the 2 contacts if the gate then works the safety sensor is the problem.

Garage door wont close completely

There are a couple of reasons this might happen. First make sure it closes by hand all the way, if not there is something wrong with the door that will need attention first. If it does close then hook the opener back up. On the opener rail at the end by your header there is a little magnetic relay that is wired to the motor head. This can be moved farther up or down the rail. This sensor tells the opener when to stop in the downward direction. Loosen the set screw and move it toward the header 1/2 inch or so and try to lower the door. Do not move it too much at one time and if you do the door will hit the ground and come back up.

1. I have an elite slide gate opener it will open all the way and after a few sec will close. 2. With the remote the gate will not stop and stay in the open position.

the auto close has been set or the motor has been set up in reverse and it is auto reverseing,make sure the gate is opening up all the way, if it is not just help it along and see what happens.
