  1. To change the code first decide which button on the remote you wish to use. Remove the screw holding the back cover. Locate the 9 pin connector. For the top large button put pin 1 to the minuse position. To use the center button set the switch to 0. To reset the code use a small screwdrive to position the switchs to +. - or 0. SEt the remove switches 2-9 abd then set the reciever switches in the exact same way. I hope this helps.

  2. Hello nailbender, I am sorry you are having this problem. The number you submitted is a part number of the logic board inside the power unit mounted to the ceiling. The model number should be located on the side of the power head or on one of the ends. You may need to remove the lens cover to see it. If you could reply with the model number of the garage door open which is mounted on the ceiling, I will be happy to provide the model specific instuctions.

  3. hendo72,To change the code on the model number listed, first you will need to erase all previous codes. To erase the codes, press and hold the SRT button on the opener panel until the light turns off (approx. 6 seconds). Now to reprogram, repeat steps 1, 2, & 3 listed in the owner's manual on page 33. Here is the link for the owner's manual. http://www.searspartsdirect.com/partsdirect/user-manuals/13953629SRT-Craftsman-GARAGE+DOOR+OPENER-manual . I hope this will help you.

      correction on that model# its a 139.53600

    5. In response to SHC-ScottD

      Scott, I have this same garage door opener. I hold the SRT button for at least 6 seconds but the light stays on for about 20 seconds. After the light finally goes off I press the remotes and they are still operating the door. Anything else you can think of for me to clear the codes?

    6. In response to SHC-ScottD

      The 41A3066 is the part number for the logic board. A model number should start with 139. If you Chamberlain remote has the same dip switches and uses the same frezencies then it should work.

      If your model has a button that needs to be pushed to program the remote, I recommend pushing and holding the button down until the light on the control board turns off. This will erase all the codes in the control board. After you erase all the codes, you can reprogram all the remotes one at a time. This should cure the problem. If your model has small switches that you have to set to program, the remote you just need to change the position on one of the switches. For instance if switch one is turned on you just need to switch it the other way. Then make the same change on each of the remotes. This should cure the problem you are having.

      Was this a response to my question? Because if it is you must not have read my question clearly. Please read my question again and give me a response that will help my situation. Thanks.

      AJinChica, I'm sorry you are having this problem with the GDO. If you have the same model as the one listed above your question, unfortunately the owner's manual is no longer available. However, I'm listing the information from what appears to be a similar model. To deactivate any unwanted remote, first erase all codes:
      Press and hold the "learn" button on motor unit until the learn indicator light goes out (approximately 6 seconds). All previous codes are now erased. Reprogram each remote or keyless entry you wish to use. If your model is different, please reply with the complete model and we will be glad to assist you further. I would also like to recommend posting your own question on a new thread. This thread is getting very confusing to follow.

  4. I am sorry you are having this problem. The number you submitted is a part number of the logic board inside the power unit. The model number should be located on the side of the power head or on one of the ends. You may need to remove the lens cover to see it. I will try to assist you without the model number. If your model has a button that needs to be pushed to program the remote, I recommend pushing and holding the button down until the light on the control board turns off. This will erase all the codes in the control board. After you erase all the codes, you can reprogram all the remotes one at a time. This should cure the problem.

For instance if switch one is turned on you just need to switch it the other way. Then make the same change on each of the remotes. This should cure the problem you are having.

    If this does not work please reply with the model number off the unit and more details. The model number should start with 139. followed by at least five other numbers. I need all the numbers.

    1. In response to SHC-JoeyS

      the model number is 139.536.29SRT

  5. I would expect the model number to start with a 139. To change the code start by locating the Learn button on the side or back of the opener. Press and release the Learn button and the LED should illuminate. There is a 30 second time limit on the next step. Enter a 4 number pin of your choice on the keypad then press the Enter keypad. I hope this helps. You can reply with a complete model number for further assistance.

  6. On this model when you change the dip switches then simply press the button on the remote and it has been reset. The opener only needs to learn the code it is on. It is not a true srt learn button in this respect.

      I'm having a similar problem with my 139.53615sr. My neighbor has captured my code and accidentally opens my door a lot. I have tried the reset procedure, but my button is Yellow and I have held it for up to 60 seconds and the light never goes out so I am not sure if I am erasing any codes (like the one my neighbor has captured)

    2. In response to SHC-FredM

      Welcome, Tx_paesan! An Expert will be by in a bit with some advice on your opener. I'll reach out to you once he posts a reply.

      Thanks!

    3. In response to SHC-FredM

      Hello Tx_paesan, the light will not turn off. You do not need to attempt to push and hold the yellow button to clear the code. I you need to do is reprogram your remote(s). Press the yellow button and the indicator will come on and then release the button. Press the selected button you want use on the remote within 30 seconds and the indicator will turn off. Then press the selected button again and the door should operate. This procedure will reprogram your remote and door opener.

      I'm having the same problem. I've used the original remote for years. It still works, but it started falling apart. I bought a universal remote and followed the setup instructions. It works, but now it opens from any other remote in the neighborhood, which is every few hours. I've changed the dip switches a dozen times and it keeps happening. Is there anyway to completely reset the receiver??

      I have the same issue as mentioned above. My neighbor has tried to reset his opener(Genie) and remote, but still can't disconnect from my craftsman. I do not see any dip switches on the motor, just a "learn" button. Please help

    6. In response to SHC-WendyFD-2

      Hi GarageDoorWorrier! I am sure that has to be frustrating for both you and your neighbor! The Garage Door Expert may ask for your model number in order to give you the most accurate answer. I will send along to him so he can still offer up some advice on getting this fixed for you.

    7. In response to SHC-WendyFD-2

      I'm having the exact same issues as mentioned above. Purchased a universal remote and got it programmed only to find that my neighbor can now open my garage. Is there a way to reprogram or a place to change the dip switches on the unit itself? Please help so I don't have to buy a new opener! Model number 41A3624.

      My model # is 139.3043. I've reset the unit (according to the manual and what you've suggested above)using the learn button by holding it down until the light turns off and repeating. I re learned all the remotes but it's still opening my neighbors door?

      haven't received anything back yet regarding this. I've reset it 3 times and my neighbor (which has an old model Craftsman) has reset his 3 times. I need a solution soon please.

    13. In response to SHC-WendyFD-2

      Hello henod072, ask your neighnor to try clearing and reprogramming his garage door opener. If the problem can not be resolved, I suggest calling a service technician.
