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

1 Answer

Garage door won't close with remotes

In August i replace my garage door opener with a new Craftsman 1/2hp model 139.53930DM (chain drive). The garage opener worked fine until December, now the only way I can close the door is too hold down the button that is mounted in the garage. One thing i have noticed is the light on the opener blinks yellow all the time. I don't remember it doing that when i installed it. There are no obstructions or debris in front of the sensor. Does anyone have any suggestions?

My Craftsman remote won't close my garage door


If the remote opens and closes while inside the garage but not outside , there are a few things it could be. Assuming it was working fine before..
1. weak battery in remote.
2. remote itself could be bad. (unless you have more than 1 remote acting the same)
3. Logic board in opener is going bad causing limited range.Is the wire that hangs down from the opener straightened out? That is your remote antenna.Some people have coiled or even cut it off..reducing range.
4. Less likely but this can happen- interference from another electronic device, wireless routers, cell phone, new appliances etc.. can reduce remote range. Any new electronics recently purchased?

Garage door opener won't close. travels 6-8 in.,


If you cannot get the light on the sensor to come on by tweaking it,making sure it is pointed at the other sensor and your wiring is not broken or shorted then your sensors need to be replaced.
