Sears garage door opener

I have an older Sears garage door opener (came with the house) model # 139.655000. I have the old (big) remote that come with the opener and a small 3 button (newer style) remote that I have used for years (8) with this opener. The 3 button remote has quit working. I have 2 other remotes that still work. I replaced the battery but it still doesn't work. Now here's the problem. The new remote I just bought has the same model # but says it works with garage door openers that have an orange learn button. My opener has no learn button that I can find and I have looked everywhere. It does have a red "reset" button but that is all. I cannot find anything online concerning this opener. Can anyone shed any light on how I can program this new opener to work since I don't have a learn button?

    I have Sear's garage door opener model number 139.664953 and can't find a learn button either. Any solutions out there?

    Same door opener unit -- "lost" the remote. No part numbers on the receiver except circuit board 14LG150C.

    My research all points to fact that this is an "obsolete" unit that isn't particularly secure or immune to stray military radio frequencies, thus replacement of receiver + remote is recommended for $45 to $55.

    Has ANYONE found a way to replace these remotes???

I just found the solution for my 'ancient' Sears garage door opener, model # 139.655000, and I figured I'd share it.

There's a separate radio module, wired to the main opener. This module is small, has a short wire/antenna, and plugs directly into an outlet.

There's a manual open/close button on this module (I didn't realize this until I got up on a ladder). This button is also a removable cover; underneath it is a "smart actuate" button -- this is your learn button.

What I did was: unplug the radio module. Pry off the cover. Plug the radio module back in. Hold down the button on the remote. Press the "smart actuate" button. This programmed my remote successfully!

    I couldn't find the seperate (receiver) attachment on my opener, just a plain push-button, wired opener. I believe that the model 139.655000 may not have had the remote receiver, and that the one mentioned in the above post may have been an add-on.

    In my case, after finding this out, I went out and purchased a universal receiver adapter from Sears for about $65 that included a 3-button remote (I believe the same unit that is mentioned by partsref above). Since my second garage door opener was a more modern Craftsman, I purchased the matching technology (315 Mhz?). Once I installed the universal receiver (very simple - basically attach the wires to the back of the opener), I was able to program the new 3-button remote to open both my doors, and our old remote to do the same.

Here is a VERY inexpensive way to fix any sort of issues like this. My issue happened to be that i purchased a forclosure and of course they didnt have a garage door opener remote (much less keys) for the house. my opener model is ancient as well... model 139.664953. It has NO learn button and from what i can tell, is from the early 90s. anyway, skylink ( has awesome gadgets that allow you to (in my case) just take the two wires from your existing push button inside your garage and wire nut those wires to the skylink push button ( which has a built in transformer allowing your door to now be opened by the included universal remote. Plus, this system has rolling code technology...which eliminates your dip switches all together. the greatest part about it is that if you already have an existing system and like it, you can simply put this system in tandem and use them both at the same time.

How do i reprogram garage opener model 139.53776

To ensure that old codes do not work, first press and hold the SR code button (Learn) on the garage door opener's control panel. Hold the button until the LED goes out. The Learn button is a colored button that is usually on the back panel to the left of the force and up/down adjustment knobs. Sometimes the control panel is on the side of the unit.

Next get a helper to make the programming easier. One person will need to press and release the Learn button. Then within 30 seconds, the second person (or a fast moving individual) needs to type in a 4 digit code and press the enter key on the key pad. The LED near the learn button will flash when the code is received.

If you reset all of the codes, you'll need to repeat the fast press and release of the Learn button. Then press a control button on the remote for most of your other door opener remotes. (There may be a pair of remotes that came with the garage door opener that will never be forgotten.)

I hope this helps.

I've got water coming in through the bottom of my door at work. It's coming in a steady stream through a crack in the marble. Can someone please give me a pointer or two?

If you have water pipes/ heating pipes in the concrete floor then from the crack I would suggest that the floor movement has broken a pipe allowing the water to flow out the crack under the door. To test this turn the water off at the mains and if the water stops flowing after a short period of time then that will indicate the fault. Allow enough time for the water in the pipes up to taps to drain back out
