There is a sensitivity switch for both directions, open and close. If you access the garage door opener in the ceiling, you will see two adjustment screws for calibrating these. I would highly recommend following the instructions in your manual, as these are life safety adjustments! Your sensitivity for closing the door is adjusted to the positive. You just need to back it off a little. Place a 2x4 on the floor of the garage where the door comes down. and when the door hits the 2x4, it should automatically come back up. If not, you adjusted it too far. Hope this helps. and remember, check the manual for your specific adjustment procedures.

SOURCE: I have a Sears HBW0777
I have the same opener. Last night I experienced a similar problem. I assumed it was the usual problem I have when it is cold out (near 0): added resistance for the bracket sliding along the bar. But upon further investigation, it turned out to be worn gears inside the unit. they ar made of plastic or nylon and they had worn down so much that they are mostly stripped of their teeth. the added resistance from the cold and dirty bar has caused them to fail once and for all.
If you unscrew the housing you can easily see the condition of your gears. But perhaps by now you have replaced your opener?

The code for the opener is on a dip switch set under the light bulb lens on the opener unit. Remove the lens and the switch set is usually located on the left as you look at it. It's either a 9 or 12 switch set. Match the numbered switches on both the remote and the receiver, and it should work! Oh, and make sure the battery is fresh.

Check the electronic eyes that sense when something is in the path of the door, sometimes they can get knocked out of place, something could be blocking them, or there could be a build up of cobwebs in the opening for the electronic eye. Typically when the light flashes it is indicating that somehow the infared beam is obstructed
