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

Craftsman 1/2 hp garage door not running at all

Hi all, we purchased a house with a Craftsman Garage Door Opener (I have no idea how old the opener is). Our previous house had one as well, so I'm very familiar with the sounds, problems, etc they have. However, with this one I am stumped.

The sensors are lined up properly, it's plugged in, lights on inside button don't dim. I push the button, and it does nothing. The motor does not run at all. No humming, not chain attempting to move, not a sound.

Does anyone have any ideas as to what I could try to see what's going on?

Thanks a ton!

DOES IT WORK FROM THE WALL BUTTON??

IF NOT YOU MAY HAVE A BAD CAPACITOR - UNPLUG THE UNIT TAKE OFF THE COVER AND LOOK FOR A ROUND TUBE THAT HAS 4 WIRES CONNECTED ON ONE END . IF IT IS LEAKING OIL OR HAS A BROWN OR BURNED LOOK ON THE CARDBOARD END WITH THE WIRES IT IS MOST LIKELY BAD.

SHOULD BE AVAILABLE FROM ANY MOTOR REPAIR SHOP

HOPE THIS HELPS

Two things. Check for a broken door spring. If okay, remove the cover from the motor housing and check for a bad drive gear. This is a white nylon gear just in front of the motor. If it is going bad it should be obvious.

Double check to make sure the sensors are wired correctly. The 2 solid white wires go to terminal 2 and the wires with black stripes go to terminal 3. If the wiring is correct then you possibly have a bad RPM sensor. The RPM sensor is a small circuit board just in front of the motor.

Craftsman 1/2hp garage door opener does not go down to floor


I'm no expert, but on a previous door opener I had (don't know the brand), the side adjusting screw basically adjusted a limit switch, which was located inside the plastic housing (where the motor is). I was able to remove the housing, figure out which limit switch was actually being contacted "too soon" on the way down and adjusted it while watching it.

Just a suggestion, you might take a look.

just keep your hands out of the way of the chain and sprocket if you do take the housing off. .

Garage door opener motor will not open garage door


It sounds like you did a really good job! My Craftsman 1/2 hp gar. dr. opener has a red reset button on it on the l/h side as you are looking at the light/motor from the garage door opening. You have to take the light cover off to be able to see it. My reset button is on the same side as the ground wire. You might check the ground wire while you're there. I really hope that this fixes it for you (and me). I'm quite sure it will as you know your way around the garage door opener already. Good Luck and Let me Know (Please) if it fixed it or not. If I think of anything else, I'll let you know. Have a Good Day!
