Sears garage door opener - opens randomly

mrs_happy_gardenDecember 3, 2009

This pasts week our 1/2 HP Sears garage door opener started opening our garage door randomly - during the day and night. The garage door simply opens all by itself unprompted. The opener is aprox. 5 years old.

Is there an electronics issue with the opener, or, by chance did someone else purchase a new garage door opener in our neighborhood that uses the same frequency as our garage door?

Look at the LED light next to the SMART/LEARN button on rear of the motor unit. You may need to remove a light lens cover in order to see it. If the light is flashing rapidly this means you have a stuck button on one of your remote controls. Take the batteries out of each remote control. When you remove the batteries from the bad remote, the light will stop flashing. This remote needs to be replaced.

If one of your neighbors remote controls is inadvertently programmed into your receiver, you door will open when their remote is activated. If this happens you will need to clear out your receiver and reprogram your remote controls. Press and hold the smart/learn button for 6 seconds or until you see the small LED light near the button turn itself off. If the above steps have been followed and the symptoms continue, there may be an electronic short in either the wall control button or the receiver logic board. In this case, remove the wall control wires from terminals 1 and 2 on the motor unit. Should the symptoms persist after the wires are removed, replace the receiver logic board. If the symptoms stop with the wall control wires removed from the motor unit, replace the wall control button, and the wires leading to the wall control button.

I have the same problem with a Sears 1/2 HP unit made in 1998. Unfortunately I do not have any instruction booklet for the unit or the remotes.

The remotes are gray with blue buttons. I know the large button which extends all the way to the side of the remote case is to open and close the door, but what do the 2 smaller buttons do?

I have zero confidence in this opener, so I leave it unplugged all the time unless it's actually opening or closing the door.

You can program an additional opener or some accessories that you can purchase at Sears with the small buttons.
