While pressing the buttons for opening code wallunit pad gives light to show it is working ,then it opens door .this not happening now seems to be not responding
Most wall buttons get power supplied from the logic board, it may be failing.unplug the operator for two minutes and replug in the power, see if that helps
If you are talking about wall mounted switch, yes it has a battery. Refer to your instructions that came with GDO, or google the wall mounted switch by model number for more info.
Testimonial: "yes but incomplete answer"
They do fail, I've replaced remotes for GDO before. You can buy wall control at Home Depot or Lowe's. You can order from amazon.Since it is Craftsman , Chamberlain made it , use their model number. You could try reprogramming the opener. Monday you could call Chamberlain help center for fee help. Good Luck

SOURCE: garage door remote won't open the garage door
The little button with a padlock on the wall control is a "vacation" lockout feature that disables the remotes. There should be a small LED on the wall control that is always on steady. When the padlock button is pressed and released the LED should be constantly blinking (indicating the vacation lockout mode is active) and your remotes should be disabled. The wall control will still operate the door. Pushing the padlock button again should make the LED stop blinking and restore the door to normal operation.

Okay...upon further inspection, my left spring has broken in two. Going to call around for some quotes to replace the spring. Thanks for the suggestions.

SOURCE: 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
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.
