I can open my garage door, but it won't close. I've replaced the batteries in both openers and I've tightened the red/white wires to the button on the garage wall. It still won't close. Any ideas?

Does it start to go down and then reverses itself? Most of them have safety mechanisms where they won't close if something is blocking them. Possibly something is tripping the sensor, or the sensor is broken.

No, that's not it. It's something different. The only way the door will go down is if I hold the button on the wall the entire time. If I stop holding it, it stops and the door goes back up. Neither car opener works when I try to close it---they only work to open the door. Bizarre!

That sounds similar to mine. It won't close properly in cold weather and it seems to be getting worse with age. Holding the button down helps.

Hi,
Don't know how your GDO is set up, but the ones I've had in the past eventually did the same thing. It can usually be cured by adjusting one of the "tensioner" screws in the motor housing. Usually there are 2 visible, but recessed, nylon adjustment "screws" which can be accessed by using a small, thin bladed slot screwdriver. One screw is for "Up" tension, the other for "Down" tension. You may have to experiment to see which direction is 'more' and which is 'less' tension on each unless they are clearly marked. NOTE: Use small adjustment increments when adjusting. You will want enough tension for the motor to close the door, but not enough tension to crush a trapped child. A test for proper tension is to put something foreign where the door meets the floor (a coffee can or something similar) and close the door. A door with proper tension should contact the item, pressure it slightly, and then open fully. The proper setting can save a pet or child.
Proper tension for the "up" position is one that opens the door fully but does not continue to pressure its upward progress once opened.
You may find that once you have properly adjusted the "down" tension that the "up" tension may need a tweak. Best of luck, and remember to adjust a little at a time.
