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

1 Answer

I have the similar problem + the light bulb is on all the time???

Hello,
I'm having problem with my Sears Craftsman garage door opener model: 139.53628SRT. Open the garage door is normal but when I try to close it, it travel down for a few seconds and reverse/pull the door back again. I have to press and hold the wall-control-button to close the door completely. Press and hold the button from the wireless remote control won't do the work as the wall-control-button. Along with that, the light bulb in the unit keeps being on all the time. It supposed to turn off after the door close, isn't it? I'll try the instruction you posted. It'd be great if we can have the graphical figures to support your instruction steps. I'm a bit savy on this. Many thanks. my email is: info07@comcast.net

HOLDING DOWN THE WALL BUTTON OVERRIDES THE SAFETY EYES.
WHEN HOLDING IT DOWN MAKES THE DOOR CLOSE PROPERLY THE PROBLEM IS IN THE SAFETY EYES.

ARE BOTH LEDS ON? - CHECK FOR A LOOSE OR BROKEN WIRE.
ARE THE EYES WIRED CORRECTLY?
ARE THEY AIMED AT EACH OTHER?

YOU CAN GET THE FULL INSTRUCTIONS AT LIFTMASTER.COM
THE MODEL # WILL BE DIFFERENT BUT THE INSTRUCTIONS ARE THE SAME LOOK AT THE MANUAL FOR MODEL 3280

HOPE THIS HELPS

The button to program the unit is near where all those white wires go.

SOURCE: 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.

Make sure that when inserting the 9 volt battery that those red & black wires are not somehow pinched, twisted or stretched. I just fixed mine... The battery terminal was crushing one of the wires and preventing the battery to supply power to the keypad. I found it out by NOT securing the battery case door and my opener worked fine. Securing the battery case door with the screw and thightening, my opener DID NOT WORK. It was that simploe of a FIX!

Unplug the opener and remove the bulb. Use a small screwdriver to pry out on the center contact in the light socket. Replace the bulb and plug in the opener.

Sears 1/2 hsp garage door opener. Remote control will not close garage door until light goes out. what is problem ?


I would suspect you have a light bulb that is radiating and causing interference with the receiver. Remove the light bulb and try. You can also try this: Unplug the unit and using a small screwdriver pull out on the center connection in the light socket. This will tighten the connection and prevent arcing.

Remote works only when Garage Door Opener light is OFF


I discovered that certain light bulbs interfere with the remote sensors. Harware stores have clear vibration reisistant bulbs for garage doors, try them instead. After spending money on a new remote, resetting remotes, and weeks of aggravation...poof.....i found it was the type of bulb I was using. Used a clear bulb and the problem went away. Hope this helps.

Garage Opener Lights will not come on


IF YOU CAN - TEST FOR 110V AT THE CENTER TANG OF THE LIGHT SOCKET.
IF NO POWER YOU PROBABLY HAVE A BAD TIMER CIRCUIT ON THE BOARD - NO EASY FIX NEW BOARD.
IF YOU HAVE POWER YOU MAY HAVE ISSUES WITH THE SOCKET OR ARE USING THE WRONG BULB - A STANDARD LIGHT BULB IS ALL THAT IS REQUIRED. SOME OF THE NEW BULBS HAVE A SIMILAR LOOK BUT DO NOT WORK IN A STANDARD SOCKET.

Main light on will not come on when door is opened/closed


For some reason, the bulbs I tested that worked somehow didn't work correctly when inserted into the door opener. We opened another set of bulbs we purchased and what do you know, the light now works. I don't fully understand as the other bulbs did work just not in the garage door opener.
