Q:

Door will not close 139663902 Craftsman Sears electronic garage door opener

A:

Hello glad to help.  Thank You for choosing Sears PartsDirect.com
 
I am sorry and do understand your frustration when there is trouble with the garage door.
 
Glad to help out.   Im  looking at your Craftsman garage door opener model number 139663902.

I see you have a very old garage door opener.   I hope the old ones work in the same aspects as the new ones do.

When a door open or closes by going a little and then stops.

1.  Forces for up/down set too low.  Pull emergency release and check manual door operation.  If no obstruction, increase the force and retest.

2.  Interupter cup not properly seated on the motor shaft.  Visualy check the interupter cup to make sure of proper installation.  Repair or replace if necessary.

3.  Defective RPM board.    No longer available.

4.  Defective Logic board.   No longer available.

Hi, I a tried to reply to you on the web site but it wouldn't let me unless I logged in and then still didn't let me. I want to make an adjustment to the door. There is an adjustment for lifting force and I want to know if that is for heavier doors. Mine is a 10 foot wide garage door and it sometimes stops on the way up. I think there are adjustments to the spring tensioners that will also help in lifting it manually. Thanks Les

Les, Based on the age of the opener I do not think the problem is with the force of the opener. I suspect the door spring needs to be adjusted. Before doing anything I recommend checking the balance of the door. To do that you need to pull the emergency release on the opener. Then lift the door. If it is properly adjusted, you should be able to lift the door with ease. Once it is halfway up and you let go of it the door should stay in place or slowly close. If it slams down the spring needs to be adjusted. I do not recommend doing the adjustment yourself because of the dangers of doing it. I strongly recommend having the springs adjusted by a door servicer. You can find a door company in your area that will do this. Once the door spring is adjusted, the opener should work fine. I hope this is helpful. Please let me know if you need further assistance. Thank you for using Manage my life. Mark T.
