Check the door sensors. They must be pointed at one another and the small light on each one must be lit and not flickering. Tweak them a bit. If you cannot get both lights to come on you have a bad sensor.

If the main light flashes 10 times when the door reverses it is a door sensor problem. Make sure the sensors are pointed at one another and the small light on each sensor is lit and not flickering. If you cannot get both lights on you have bad sensors.

Make sure the brackets for the sensors are tight and the small light on the sensors is not blinking ever so slightly. You also might try shading the sensor so that the sun is not shining directly into the lens.

If the main light flashes 10 times when you try to close the door it is a sensor problem. Make sure they are not flickering ever so slightly and that they are not loose on their brackets. Tweak them a little bit.

You need to reprogram the remotes by briefly pushing the learn button on the garage door opener until it flashes once, then release the button on the garage door opener.

Now press the remote button once until you hear the garage door opener click, now press the remote button once again and the remote should be programmed to work for that garage door opener.

DO NOT press and hold the garage door opener learn button for more than 10 seconds or you'll erase all programs and have to relearn all the remotes, including your car ones.

Hope you found this very helpful and best regards.

If the small light in your wall control is blinking it is in the lock mode. Press and hold for 3 seconds the button with the icon of a lock. This will toggle the lock function off.

I have no idea what a 132C2105-3B is but try this. Hold the button down on the remote and then press and immediately release the smart/learn button. If the remote is the correct one for your opener it should work.

Garage door opening/closing problem


Could be a bad wall button or a smashed wire.
Anytime a door opens and/or closes by itself, or remotes work intermitantly I look for a smashed wire between the motor unit and the wall button or a bad wall button.

If the wire is smashed the insulation becomes so thin that power will leak thru the insulation and activate the door or interfere with the remote.

Loosen the staples with a small screwdriver and slide the wire about ½ inch to move any areas of thin insulation away from the staples.

The second thing would be a bad wall button or a remote with a sticking button.
Or a remote in someone’s purse that gets the button pushed by other stuff in the purse.

The test is to disconnect the push button wires at the power unit. If the self operation / interference stops you have located the problem. If you reconnect the wires and disconnect the wire at the wall button this will tell you if the problem is the wire or the button.

HOPE THIS HELPS
