    I have this problem. If I program the password again it works for a week or so but then stops again. It seems to lose the password.

Have you checked the battery in the keypad itself? It is usually a specialty battery that you would need to purchase at a hardware store.

A wireless keypad will not work with your opener. Your opener is pretty old and the new models are much safer. You might consider replacing the entire thing.

You have either a broken door spring or the drive gear in the motor unit is bad. The drive gear is a white nylon gear just in front of the motor and it will be obvious if it is bad.

Try programming the keypad by doing this:

Press and immediately release the smart/learn button and then walk over to your keypad and key in any 4 digit code you like and press enter. If this doesn't work you keypad has quit.

The inside button is hard wired. The keypad is a small radio transmitter. If the battery in the keypad is good and it doesn't work when you put in the code it has probably just quit.

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.

Remote only closes the garage door, will not open it


Anytime a door opens and/or closes randomly or doesn’t work consistently I look for a smashed wire between the motor unit and the wall button.

If the wire is smashed the insulation becomes so thin that power will leak thru the insulation and activate the door or interfere with the remote signal.

Loosen the staples with a small screwdriver and slide the wire about ½ inch to move any areas of thin insulation away from the staples.

The second thing would be a bad wall button or a remote with a sticking button.
Or a remote in someone’s purse that gets the button pushed by other stuff in the purse.

The test is to disconnect the push button wires at the power unit. If the self operation / interference stops you have located the problem. If you reconnect the wires and disconnect the wire at the wall button this will tell you if the problem is the wire or the button.

In your case the expansion of the wall in the afternoon may be enough to cause pressure on the wire to increase the problem – works in the morning but not the afternoon.

Also after you change the batteries you need to reprogram the remotes.

HOPE THIS HELPS
