Sears LiftMaster - Answered Questions & Fixed Issues

keypads on average have a battery life expectancy of 3-5 years depending on the usage , if your garage is a main thouroughfare like so many homes are they will last for 1-2 years , so what i would sugest is use top grade duracell batterys for this keypad and also check your keypad at nighttime just to see if the pad is lit up , generally when you use it it will stay lit for approx20-30 seconds and shut off , if one of the rubber keys are warped and are stuck from heavy usage ,you would never notice it and your lights in the keypad can be running day and night , thats why i ask you to check it at night! if the lights are off when you approach it then this would not be the issue but it,s one way to find out what,s causing your batteries to run down so fast ,I would definetly try that first Forrest , 2-3 weeks is unheard of and you might even be able to get a replacement from the manufactuer for being possibly defective , Hope i was able to help you with some idea,s Forrest and if you thought i was helpful please leave me a nice rating Sincerely Glenn Mayer

It sure could be the capacitor. The symptoms are right for a bad capacitor.

Your opener is very old and I'm positive you can no longer get the remotes. You might look into one of these.

Craftsman - Model #00953751000

It is a universal remote and receiver that operates on the new frequency and has the rolling code feature.

The wireless keypad should work but the remotes should not. I suspect a bad wall control but there is a possibility of a bad logic board. If you have a neighbor with a 3 button wall control see if they will let you borrow it to eliminate that problem. Just make sure you note which wire goes where on the back of the control. They are color coded.

The button should be on the back of the motor unit. You may have to remove a light lens to find it.

How can I find out the correct settings for this blue relay?

Good Morning:

I also substituted Floescent Bulbs for the standard bulbs. The bulbs would not light up although the relay was working. It seemed that the Florescent bulbs had a somewhat shorter neck. What I did was unplug the drive system from the outlet and then bend the metal connector in the socket so that it would come out further towards the opening of the socket. I then repluged the drive. The Floercent bulbs now have contact and are working perfectly. Simple problem with a simple solution.

I had the same problem. Although it appeared to be the logic board, on mine it actually was the connectors between the logic board and the power supply board.
There are 2 connections on the logic board. One white connector with wires going to the main unit, and another set of connectors that plug directly into the smaller circuit board that holds the step-down transformer (120vac - 22vac). These pins were not making good connection between the boards. I simply bent the pins slightly so they would make better contact on the logic board and have not had a problem since. This must be a weak point on these door openers. Purchasing a new logic board would work too, as the connectors are newer and tighter.

garage door keypad code... how do I reset it? I have a craftsman

One possible reason. (RF) Interference from an ultrasonic humidifier. The radio wave created to create the mist will cancel out a garage door opener I learned it the hard way I almost replace two garage door opener's but I turned off humidifier and everything worked in my Internet works better now too. Just passing this tip on hope I helped.

Pull the logic board and check it for burnt or missing traces on the printed circuit. Thunderstorms love logic boards.

mikey-moore's advice helped me figure out what to do but it's not exactly what I had to do. Manually open the garage door all the way. Then hit the automatic button you normally would use to open and close your garage door. The bracket slides back and locks into place. Hit the automatic button again and the garage door should automatically close.

the craftman george door opener will not close the light blinks five time. what is that?

If you can not open the door sounds like you might have a broken spring. Call a professional do not try to repair the spring yourself.

Remove the eye wiring from the opener entirely and try it that way.

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.

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

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.
