I have a stanley garage door opener model # ST205.A09 When it opens it goes up too far and when it closes it comes down with alot of force. When this first started it went up about 2 feet then came down....

Make sure the counter balance springs are ok. Most garage doors have 2 springs to provide counter balance for the door. Your garge door opener may have enough power to still operate even with one springs broken however with one springs broken would hit pretty hard. It the springs look ok I would release the door from the opener (while in the down position) using the little rope that hangs down and operate the door by hand to ensure it goes up and down smoothly. Most problems are due to friction caused by bad rollers or failed springs. If this is not the issue let me know.
Hope this helps

My garage door opener just stopped working out of nowhere

1st Check to see if the saftey beams on the door track (near the bottom of the door,,,,,one on either side of the garge door) are still aligned. If they were hit or missaligned the door will not function.
The LED lights on the sensors will blink if not aligned properly.
2nd. If that doesn't work them try resetting the opperator by un plugging it. Wait 1 minute before plugging it back in.

Hope this helps
