Does the door touch the floor? If so your down limit needs to be decreased.

Does it open back up mid-travel? If so your down pressure needs to be increased.

Read your manual about setting the safety reverse system if you change any settings.

Opener can be closed by pressing only the ENTER button if the One Button Close feature has been activated. This feature has been activated at the factory. To activate or deactivate this feature press and hold buttons 1 and 9 for 10 seconds. The keypad will blink twice when the One Button Close is activated. The keypad will blink 4 times when One Button Close is deactivated.

Okay, I'm having an issue with my Sears Craftsman garage door opener. Not exactly sure of the model number, but can dig it up if that's necessary. Symptoms: 1) Door opens fine from either wall button or...


It sounds like you have a problem with your wall button. I would remove the button from the wall and then disconnect the 2 wires on the back. Remember where they go as they are color coded. You can then momentarily touch the two wires together to check the operation. There isn't enough voltage there to bother you.

One thing to remember. If when the door reverses the main light flashes 10 times it is a door sensor problem and nothing else.

Liftmaster pro 1/2 hp wont shut in one button press


You have a door sensor problem. Either your main light bulb is burned out or you don't have one in your opener. The clicking sound you hear is the relay for the light. Both of the door sensors should have a small light that is lit. Tweak them until they are.

Sears Craftsman Garage door opener does not open or close


The drive gear is most likely stripped. It is a white nylon gear just in front of the motor. The parts number is 41A2817 and is available from Sears or any good door opener service company. It comes with instructions.

Garrage door opener ability to close the garrage door


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?
