SOURCE: Installed Chamberlain Whisper Drive but door slides backwards

It sounds like you may have a spring problem. Release the door from the opener and see how it acts manually. Open it as far as the opener does and then see what happens when you release it. Also the weight of the door should give you a clue.

SOURCE: I have a Sears Craftsman HBW0777 Garage Door

I had the same issue yesterday with my remotes which are model 850CB. I fixed it by following these steps on Chamberlain's help site:
1. Press & release the "learn" button on the motor unit. 2. Within 30 seconds, press and hold the button on the remote. 3. Release the remote button when the light bulb on the motor blinks. It has learned the code. and enter your remote model number for re-programming instructions.

That worked for me. Not sure why it "lost" the code in the first place. By the way, I only had to do this for one remote, the other started working after the first was re-learned.

SOURCE: I have problem in my garage door. I have manual

Does this opener have intellicode opn it? if so it can teach itself the code. What excactly are you wanting, are you needing to find out what the code is on the opener to program the remote? Is your opener a Genie model also? I also need the model of the remote to find the coding info on this.
This is from Genie themselfs. ( Remotes manufactured after 1996 should work with your Intellicode® opener. Pre-1996 remotes use fixed-code sequencing and are not supported by Genie® Intellicode® technology. If you are unsure about when your controller was manufactured, contact us, your local Genie® retailer or your local Genie® ProTM dealer.)

How do I replace the motor and gear drive on Chamberlain MODEL hd900d OPENER

Purchase the full kit. Not the partial kit. The instructions come with the kit. Be sure to follow them. The position of the chain and the opener when you reattach the chain are Important. It's not beyond that the ability of a handy person.

The gears are all the same with the exception of the belt drive units that have a different top sprocket , you can find the part # on the internet simply by putting in the model # of your opener and identifying whether you have a belt drive or chain drive machine , you can also find the part on Ebay by putting sears/liftmaster or chamberlain sprocket gear assembly in the description ....All 3 of those models are made by Liftmaster being the main Brand ! Liftmaster manufactures the sears craftsmen for Sears and also goes under the chamberlain brand name that k mart and Home depot and Lowes sells ! Liftmaster is the worlds largest manufacturer of garage door openers and all 3 machines are interchangeable with their parts ! Hope this helps you Sincerely Glenn

My belt broke on my model 139.655000 sears robust automatic garage door opener. I have misplaced the belt and don't know the length of the belt to buy a replacement. Do you know the belt i need?

The part number for this belt is STD303310 and is available from Sears for $4.49. I would almost bet you that any good door opener service company in the yellow pages would have one on the shelf.

Garage door close but motor keeps running

The close setting limit switch needs adjusted. Once it is adjusted it should work just fine.
