CHAMBERLAIN WILL NOT RESPOND TO REMOTES FROM STREET.

I HAVE A CHAMBERLAIN OPENER ON ONE DOOR. A FRIEND GAVE ME HIS OLD CRAFTSMAN OPENER. I INSTALLED IT ON MY OTHER DOOR. NOW MY CHAMBERLAIN DOES'T OPEN WITH THE REMOTE UNLESS IT'S REALLY CLOSE TO THE OPENER. I UNPLUG THE CRAFTSMAN AND IT WORKS FINE. WHAT CAN I DO, OTHER THAN TAKING OUT THE CRAFTSMAN ?

Sounds like "cross talk" interfence from the other operator. You can get a plugin external reciever that should work with your current remotes. Try to get as much distance as you can between the working operator and the new reciever.

You must have an older vehicle or the homelink has reverted to an earlier technology and you will have exactly the situation you describe. You will just have to use the remotes that came with the opener.

The precise remote issue


Try holding down the wall button. If this does work the door as you hold it down then the problem is misaligned sensors. If it is not that then more than likely the logic board is not good. I have never seen a whisper drive that has a door bell button and only came with one remote though???Thanks BB

Chamberlain garage door opener unit-is it compatible with craftsman keypad?


Hello,Linda well this is your lucky day ,I have installed garage door openers for sears for 10 years and i can tell you that craftsman,chamberlain ,and liftmaster are all the same machine and manufactured under the liftmaster name , if you buy it from home depot it will be a chamberlain ,if you buy it at sears ,it will be a craftsman, and if you go to commercial building supplier it will be a liftmaster! now getting that out of the way even though they are all compatible ,there is one thing that stands in their way and that,s time ,For example if your chamberlain machine is 5 years old and you went to sears last week ,the chances of the frequency being the same are not good , most likely you have the wireless keypad , one way to test the sears keypad against the chamberlain machine is to locate the smart button on your machine ,this button allows for programming of remotes and keypads , to test and see exactly what im talking about take your remote and locate the smart button ,if you have three buttons on the remote press one of the buttons that are not being used on the remote ,above the smart button their will be a blinking light ,if you press your remote button you will notice the light go from a blink to a rapid flash , This is telling you that you are sending a signal for programming to the machine , well the keypad is exactly the same all you have to do is push the enter button on the keypad and have someone watch for the rapid blinking light ,if they are compatible the light will blink rapidly on the machine so all you have to do now is have someone press the smart button once on the machine your indicator light will now be a solid light you will have approx 60 seconds then to put a 4 digit code in the keypad and then press and hold down the enter button on the keypad , at this point you will notice the lightbulbs on the chamberlain machine to shut off and come back on this is to tell you that the machine accepted the code , after thats been done you can use your keypad , you can also find the owners manual to the chamberlain and follow the same instructions to programming the remote , they are identical in programing , if your keypad is not the same frequency you can also tell by looking at the frequency code on the backside of the keypad and also the chamberlain unit usually where the light bulb is will be its code

Craftsman keypad not responding


On the back of the motor unit near where all those white wires go you will find a button. Press and immediately release that and then walk over to your keypad and enter a four digit code of your choice and press enter. You should be good to go.
