simple , i was a sears installer for 10 years installing garage door openers so your in luck , just locate the smart button on the machine ,it would be on the back or if your looking from the back at the back ,it could also be on the right side depending on if the machine is a sideways mounted machine or frontmount, after locating this button which maybe green/orange /or purple in color also depending on your model ,the newest sears machines are purple buttons ,and 5 years ago they were orange and the older ones would be green ,...ok so after you,ve located it just push it once and you will see a solid yellow indicator light come on , now go over to the keypad and put your 4 digit personal code in after that press the enter button AND HOLD IT for around 3 seconds , at that time you will see the lightbulbs on the machine go off and then click back on , and THAT,S IT! plain and simple , now go proramm your remote! hope i was of help to you , and if i was leave me a nice rating Sincerely Glenn mayer

I can't tell if you're question is accurate, are you saying that the key pad will only open the door and never closes it or that it will only do one direction then you have to use the remote? If you're saying the keypad will not close the door at all, that may be a safety issue since closing doors can potentially damage property or worse, if your saying the remote works both ways then you probably need to reset your opener and keypad. Cut the power to the opener, leave it disconnected for five minutes. Reconnect and try keypad again. If this doesn't resolve the problem them you may have a bad circuit and will have to call a pro.

take out bolt from rail that trolley is stuck against. try it now. happens sometimes

is trolley jammed against stop bolt. take out to release tension on chain. may be bad circuit board. how old is unit.

Remove the cover from the motor housing and check the drive gear.

I had the same problem and I found an old Liftmaster keypad instruction handbook. Check out the picture below and follow what it says. It worked for me! P.S. Sorry if the picture is hard to see. P.P.S. To change your 4-digit PIN: Enter existing PIN, press *, enter new PIN and press *. To test and use, enter your new PIN and press the 0 key.

The most common problem for your situation is that the battery in your wallmounted key pad needs to be replaced. unscrew the little screw on the face of the device, remove the battery and replace it with one just like it. Radio shack usually has these batteries

Check this it may be your problem. https://youtu.be/NxBeX-B5usA

For some reason, the bulbs I tested that worked somehow didn't work correctly when inserted into the door opener. We opened another set of bulbs we purchased and what do you know, the light now works. I don't fully understand as the other bulbs did work just not in the garage door opener.

It sounds like the door sensors have been bumped or somehow gotten misaligned. Tweak them until the light on each one is lit and not blinking. They must be pointed at one another.

Don't tighten the chain. It sounds like you have either a broken door spring or the drive gear in the motor unit is going bad. Release the opener from the door and operate it by hand. It should be easy enough to raise that your wife can do it with no problems and it should stay put when released about waist to shoulder high.

Sounds like your drive gear is bad. It is a white nylon gear just in front of the motor. It will be obvious.

did you use the manual release to unlatch the door from the opener? You may have a problem with the door binding and opening it manually will confirm that. You may also have misaligned the sensors at the base of the door so check that too.

Check the spring above the door, mine would go up a couple of inches and we found that the spring had broke.

If motor continues to run but no chain action check for missing chain tooth or cam gear worn.

If the chain is loose I would definitely tighten it up to remove the sloppiness of the drive. That will in turn help you to accurately find the sweet spot that is currently eluding you. And you have to work fast because you do not want to overheat the motor.

Locate the smart/learn button on the rear of the motor unit near where all those white wires go. Press and immediately release this and then walk over to the keypad and key in any 4 digit code you like and press enter.

reprogram the system with the control fob as it indicates that the program is corrupted possibly from recent power fluctuations

My garage door opener will start to close then stop and go back to the open position. If I put pressure on the door as it is closing sometimes it will close all the way and sometimes it will return to the open position. Can you help me. Thanks [email protected]
