If after programing, it still does it, erase the codes in your neighbors opener and reprogram it. This might sound crazy but after all of that and it still does it you have a bad circuit board.

Check for a broken torsion spring.

Sounds like a spring tension problem. Best toi call a professional as retensioning the springs can be a source of serious personal injury.

If it came with its own remote (probably), then you'll have to use the new remote with it - they're all keyed to individual garage door openers, as it should be; otherwise, anyone could use any old remote to open your garage door.

I think the adjustment mode is on. For example, that's from Craftsman manual: "" Setting the Force The force setting button is located on the left panel of the motor unit. The force setting measures the amount of force required to open and close the door. 1. Locate the purple button on the left panel of the motor unit (Figure 1). 2. Push the purple button twice to enter the opener into Force Adjustment Mode (Figure 2). The LED (Indicator Light) will flash quickly. 3. Push the remote control or control console (Figure 3). The door will travel to the DOWN (close) position. "" Actually, you should just read carefully your garage door opener unit's manual. Craftsman Garage Door Opener Remote

Deb, that reversal is a child safety device - if the bottom edge of the door detects contact with any object, it'll immediately reverse so it doesn't kill a child. Or a cat, dog, whatever. The opener mechanism should have a stop switch that prevents the door from closing hard against the floor - that stop switch needs to be adjusted so that the door will stop JUST before hard contact. That'll take care of it "bouncing" off the floor & reversing. As to it reversing before it touches the floor... examine both guide rails closely to see if there's any obstruction that the door's bottom edge may be contacting to trigger the child protection reversal switch.

It sounds like the down sensitivity is set too weak. Try adjusting it a little bit stronger on the down setting.

9 volt battery access by prying down the bottom half of the front of the panel.

That sounds like an adjustment issue. Say you leave something in the path of the garage door coming down. As soon as it hits it, it is going to immediately stop and move back up. With the garage door improperly adjusted, it is "thinking" it is hitting something when it touched the ground. There should be adjustment screws on the motor. Check your user manual to reference.

Take the stop bolt out and run the garage door down.
Adjust your up travel limit so it spent open up so far.
Replace the stop bolt and nut.

Many openers have a short length of wire that serves as a primitive antenna; ensure the wire is hanging free. The remote is a radio frequency transmitter, the other end in the garage has a tuned receiver. Either one of these can drift from their original operating frequency which then can cause the system to fail. Most modern openers are encoded so that they can resist operating with CBs and amateur radio signals and most require a one-time operation that allows the inside receiver to recognize (and remember) its dedicated remote by its frequency and the unique code the remote produces. While this principle makes openers more secure, it also allows for more failures of the type you are having. Take a look at the manuals available at the following site to see is there is one close enough to your model number to let you restore the programming between remote and receiver: Free Craftsman Garage Door Opener User Manuals ManualsOnline com

Carefully align the sensors at the sides of the door.
