Question about Sears Craftsman LiftMaster Chamberlain Garage Door Opener Wireless Keypad Model 976LM Security+

1 Answer

Door opener will not engage as mechanism moves along the chain track

The motor works ok, but it seems as if something is not engaging as the mechanism runs along the chain track when I press the house mounted key pad. Nothing happens when I use the in-car opener.
Your help would be appreciated.

Make sure the rope hanging down has not been pulled. If it has the door has been disengaged from the opener. You can correct this by flipping the metal part up (that the rope is connectd to) toward the drive track. Then open or close the door using the remote. The track should grab the door again.

    This is the exact same problem I'm having, and I've flipped the rope mechanism up. I had pulled it down to open and close the door manually. But now I am ready to re-engage it. The Black mechanism will run down toward to front of the garage door when the door is closed,.. but with the rope up,.... it's still not engaged. The steel thread attached to the chain is outside of the mechanism. Could this be the problem? If so, how can I fix it?

Opener buzzes 3 seconds does not engage anything


Something in the drive is slipping or jamming, and the opener controller is shutting down the motor after three seconds to protect it from burnout. Check the gearbox and chain. Also look for loose brackets; if the chain guide or door twists it can cause binding.

My Sears 3/4 HP garage door opener opens the door about 1', then will not go past this point. It will close it as well. I have taken the door off the chain and the chain will run without the door...


1. disconnect the door from the chain. 2. inspect the door again, try oiling the rollers and joints. It is the chain that lifts the door. Try manually lifting the door. If it still does not lift open, it is the door and not the Opener unit. 3. Although you don't see kinks, look for any obstructions eg. the track. 4. Make sure the track has not lossened out at any point. 5 If you can lift the door,. connect with the chain. Goog luck. Basically I think it is the door mechanism that has some how misalligned.

Motor runs but door won't open. checked chain, seems to be ok


Hello,

The problem is not the chain, it is the plastic gear in the unit of the liftmaster Garage Door 1/2 Hp.The plastic gear is not engaging, although it sounds like it is working.

You will have to replace it with a new one, then the liftmaster Garage Door 1/2 Hp will be able to open up once again.

Once you open and remove the old gear, Be sure to thread the screws in all the parts before you install them. Pre-threading them once would really help. Secondly, label the wires on the back of the opener before lowering it to the ladder, so you can put them back in their proper place.

Hope this was helpful.
Goodluck

My craftsman 41a4315-7d garage door opener is not working the motor seems to engage however the chain is not moving. What could the problem be?


Remove the cover and check the drive gear. It is white nylon and is just in front of the motor. You will find it is stripped. The part number is 41A2817.

It moves up a few in. then stops. Then you push the button again it closes hard aginst the floor. I disconneted the dr andf it still dose the same thing.


The opener has lost track of what is open and closed. This MIGHT be due to damaged gears, but first get a manual and do the initial setup work.

You could disconnect the motor and manually move the carriage back to where is should be, then engage the motor again.

If this is a chain drive, the chain may have slipped cogs until it thinks the door is up when it is only inches up.

Loosen the chain enough that you can remove it from the pulley on top of the motor unit. Now with the door closed run the motor until the pulley turns in the clockwise direction and stops. Put the chain back on the pulley and tighten. You may have to tweak the up and down limits now.
