How do you fix a dip and crack in garage concrete? Our garage has a crack and is dipping down.

Make sure the dip switches on the door opener match the dip splotch setting In the motor. But first check to see if the electric safety eye at the bottom of the door and the reflected are clear and lined up.

Usually on the backside of your opener you will see some dials( for adjusting up and down force so don't mess with them) in the same area you should also see a series of tiny, usually white, switches( dip switches ) with numbers. You will notice that the switch positions vary, some will be up and others will be down, that is how the code is set so that the opener recognizes your remote( inside the battery compartment of your remote are more dip switches that are set to the exact same pattern, hence they communicate with each other) The mathematical odds of this are really high, but it sounds like you and your neighbors dip switches are both set to the exact same pattern/code. One of you will need to change the position of your switches on both the opener and remote. Please post if this is the case as I am really curious/ will be amazed if this is the case:)

This was a first generation learn button model. Antiquated by current technology standards. It was a two channel system. One channel for a dip switch remote, the second for a 66LM key pad. No way to erase the programming, however, by programming in a dip switch remote (61LM with the dip switches set to new positions, and a 66lm set to a new entry code) will purge the two channels of their previous memory, now set to the the new settings.

You don't need codes. I'm not sure what you are trying to do but to program the opener for a remote you need to hold the button down on the remote while you press and immediately release the smart/learn button. The smart/learn button is on the rear of the motor unit near where all those white wires go.

Set those dips any way you want to. Just make sure everything matches.

Many of these devices use a code that changes each time the door is opened and closed. This feature is used to keep potential bad people from learning your operational code and entering your garage. You may have a communication problem whereby the Garage Opener needs to be reset. You may try to change the settings. If you have dip switches on the main unit in the garage, change the dip switches to another setting and write down the numbers in the order that you have the set them, Then go to the remotes, hand held and hardware placed on the outside door, and change the settings on these devices to MATCH up with the inside unit. This is a good time to REPLACE the batteries also.

I would go with a chamberlain clicker on this issue. These remote are phased out and the 9 dips don't work well with them. Thanks BB

Put new batteries in the remotes.
Check the DIP switches in the opener
Check the dip switches in the remotes. They must match the opener.

open the remote there are dip switches in side and also the same looking dip switches are in the door opener check to see if they match
