craftsman garage door opener close and open again

15 years ago

We have a craftsman garage door opener (part number: 41A4315-7D, dated as 12/02). It closes and then opens again when the door touches the ground. Does anyone have any idea what the problem could be and how to fix it? Thanks,

First make sure there is nothing between the bottom of the door and the floor. If not, your door is evidently expecting to travel downward further to fully close.
There is a 'down limit' adjustment screw on the side of the drive unit. Turn in in the direction indicated to decrease the travel in about 1/2" increments until it no longer reverses.
This is also a good time to check the chain tension and security and proper operation of all associated hardware, including the neutral balance of the door when operated manually.

If the door reverses after it hits the floor then it is traveling to far. Adjust the down limit located on the side of the motor unit. You will need a small screwdriver and you will need to turn the control in the opposite direction of the arrow printed on the cover. If the main light on the opener is flashing 10 times as the door reverses you have a sensor problem and will most likely need to adjust them so they are pointed at one another.

Ok.. Just try running the garage door by pushing the button and see if it catches the latch just fine. It will probably be just fine.... What your friend was trying to tell you to do is to grab the garage door and manually open or close it to catch the latch back onto the chain. You don't want to pull on the red cord when you are doing this - just grab the bottom of the door and either open it or close it to catch the latch. You REALLY don't want to do this with all your strength - or you might break something in the garage door latch.. It's usually harder to open and close the door - so it takes some strength to open it up without the help of the motor... but you want to go slowly when it's hooking the latch back up or you might break that part. Here's what is going on.... The Red pull handle thingey has a spring loaded latch inside it... kinda like how a door knob works. That latch grabs onto the hole on a plate connected to the door opener chain - and the garage door goes up and down when the motor runs. (It holds together like how a door latch holds a door closed) When you pull the string - you just pull the latch out of the hole in the metal plate connected to the chain.. like how turning a door knob lets you open a door.... and you can manually pull the garage door go up and down without the motor moving the chain. Does this make sense...

Have you priced another circuit board to see if replacing the board is reasonable vs a complete opener? From your explanations, it sounds as if a logic board is bad. Can you relate to how this started? I have had two openerÃ¢ÂÂs receivers to go out during the same storm (with no action with the bad receivers). It would be good to have another receiver to try with the opener because both would have logic boards/circuit boards in my opinion. I have 4 extra openers from the 80s garage/flea-market sales. They have all worked and lasted well with maintenance (mainly lubricating). My first two original used units are still working (with 1 starting capacitor and 2 receivers replaced). Have you fed your info to the Openers Tech Support that I have heard others make reference to? I think they would know which board (receiver or opener) is bad. Good Luck! loger

I tightened the chain with door closed with adjuster at the top of door - bolt with 2 nuts on it at end of chain..and no luck with the door closing..but I did find a fix to my issue. I found it in a manual online at http://homeappliance.manualsonline.com/manuals/mfg/craftsman/craftsman_garage_door_opener_product_list.html I didn't find my exact model opener but found one that looked similar...page 28 model 13953920DM I made an adjustment to the down force on the back of the opener. (far right adjuster) - Move dial clockwise one or two ticks and now I can push the button once and the door goes down..My setting was on 1 and now I moved it to 3 Hope this helps someone else... Here is a link that might be useful: Home Appliance manuals online

We had a similar problem and the fix was simply aligning the sensors. It is so easy for them to get bumped out of alignment.

When we wanted to install an opener in our old place, everyone swore about the craftman openers so we had one installed around 2002 and from the git go it had that problem ALL THE TIME, drove us nuts. It was the worst opener ever and we then understood why many refer to the craftsman products as "crapsmen". After moving into our home 2.5 yrs ago, we had the same problem with the craftsmen that came with the house. We replaced it with a Champion, have not had a problem ever since.
