There must be something blocking or making it difficult to move, check the belts and lubricate the moving rollers.

My garage door starts down then goes back and the motor light flashes 10 times. The owner's manual only refers up to 6 flashes.


Richard, what is the make of your GD Opener unit? However, make sure the antena wire on the unit is turned up. 2. sometimes direct sun on the sensors prevent operation from the remote. 3.adjust sensors on both sides making sure the green or red lights are on.4. check the remote battery ensuring red light works when you press the remote button. 5. finally, has on vacation switch on the unit has not been switched on.

Door goes down and when it stops at botton, it turns and goes back up ??? Need adjusting ..How can I adjust???


Adjust the position of the door by using the black and purple buttons. Black moves the door UP (open) and purple moves the door DOWN (close)
Setting the up position: 1. Press and hold the black button until the LED starts flashing slowly, then release. 2. Push and hold the black button until the door reaches the desired UP (open) position 3. Push the door control or programmed remote control. This sets the Up (open) position and begins closing the door. 4. Immediately when the door begins to close press and release the black or purple button. This will stop the door Setting the Down position: 5. Push and hold the purple button until the door reaches the desired DOWN (Closed) position. 6. Once the door is closed, If there appears to be too much pressure on the door, you may toggle the door back and forth using the black and purple buttons to reach the desired closed position. 7. Push the door control or programmed remote control. This sets the Down (closed) limit and the door should open.

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.

Door goes up when I press the button, but not down


If when you close the door the main light flashes 10 times and the door reverses to the open position it is a door sensor problem. Check to make sure the small light on each sensor is lit and not flashing. They must be pointed at one another to work properly.

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?

Pressing remotes the door won't go u[


It sounds like you have the lock enguaged. When it is flashing it locks out all remote access. Hold the lock button for 3 seconds. The green light should go solid. On the issue of closing, it is most likely a safety eye issue. Hold down the wall button. If it closes it is the safety eyes. Holding the button overrides the safety eyes. Make sure that thelight on both eyes are both lit.

REMOTE CONTROLS WILL NOT WORK-WALL BUTTON FLASHING RAPIDLY


Does your wall switch have a lock feature? By pressing the lock button, the remote control is disabled. A flashing light indicates this feature has been activated.

To deactivate, press and hold the lock button for 2 seconds. The flashing should stop and your remote should work again.
