If you changed the battery in the keypad and it drains the new battery then it is bad.

I have a Chamberlain Liftmaster Professional 1/3 hp garage door opener. I'm unable to find the model number, but it was made in April 2004 and has an orange learn button. It has been working fine since...


Do you mean the numeric keypad is no longer controlling the garage door? If so, have you changed the battery for the keypad? Frequently, if the battery is low, the keypad will stop working when the door is closed but works to close an open door. On most Chamberlain garage door openers, this is a 9V battery. You may need a small Philips screw driver to open the battery compartment at the bottom of the keypad.

After changing the battery, try the learn code procedure again. I've found it easiest to have two people involved when programming the keypad to the garage door opener. One handles the Learn button and the other types in the desired code.

I hope this helps.

Keypad and remote will not open door


Did the remote and keypad work before you changed the battery? Changing the battery in the keypad should not affect the remote.

Keypad Chaimberlain 32B2171-1 does not work any more


You can try programming but if it still doesn't work then your keypad is just bad. Locate the smart/learn button on the rear of the motor unit near where all those white wires go. Press and immediately release it and then walk over to your keypad and key in your 4 digit code and press enter.

Wireless keypad will close door but open


WHEN YOU CHANGE THE BATTERY YOU NEED TO REPROGRAM THE UNIT.

IF THAT DOESN'T WORK YOU PROBABLY HAVE A BAD KEYPAD.

HOPE THIS HELPS

Keypad drains batteries rapidly


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

Craftsman garage door opener remote failure


You may be receiving interference. Take all the batteries out of the remotes and try them one by one. You will not have to reprogram them. If you find one shortening the range of the others then get rid of it. Or it may be an outside source. Worst case is you will have to replace the logic board. Thanks BB
