I have an 8 year old Craftsman 1/2HP garage door opener. For several months now, when it closes, it comes back up and I have to click my remote again to stop it from returning up. My husband has tried to troubleshoot it, but no luck yet. Any ideas on what might be happening or any parts that might need replacing?

First check the manual and see if your model has a "code" for the cause. Some will flash the light bulb and/or have another indicator on them.

There are several things that can cause refersals.

1. The photocell (safe-eye). If it missaligned so that it barely works then vibration or twisting of the mount can caue it to flag that there is an obstruction. In my cause I had the manual rope (one to close the door, not the opener release) that would flop in front of the safety and block it. I have hear of one case where cobwebs had formed that would sometime block the IR light.

Also have heard of cases where bright sunlight would interfer with the receiver. If that is the case you will only have problem during a certain part of the day, which part depends on the direction that the door faces.

2. Over closing. If the down limit is set so that it is well "below the slab" it will keep trying to close it and the extra force will cause it to reverse. Start by adjusting the limit so that stops about 1" above the floor.

3. Over force limit - there is a force limt on opening and closing. If the door requires more force than the door will reverse.

Start by disconnecting the operator and check the manual operation of the door. It should be smooth and balance; ie, if about 1/2 open stay there, if 2/3 open then continue to open when release, if 1/3 open then close when release.

If you feel and tightness, roughness, unbalance or the light get the door fixed first.

Then run the opener without the door connected. Check for any needed lubercation or binding in the opener. If none then you can use the closing force.
