    small red button is to set up the remotes.....once operator is working again, will probably need to reprogram remotes to work.

    first things first, what maker and model opener do you have. was the door in motion when the opener stopped working

    let me know,

Raynor garage door motor won't run and won't open the door. It is not sending power to the system despite being plugged in to a working outlet.


More than likely, the transformer in the opener is fried. You need to verify 110V power coming into the transformer, and that there is 24V AC power coning out of the transformer

smart or learn button is located on the back of the garage door opener. (the machine that is over your head) on most units such as liftmaster, craftsman, chamberlin. its on back or side by the light bulb and is green, yellow, orange/red, purple. genie units are black button behind light cover. or external on old units. push and hold your cars homelink button will blink slow, at the same time push and hold the remote for the garage door. led light in car will blink fast. let both go. now go to the garage door head unit, (overhead) and push the learn button. button will blink and you have 30 sec. to go to car and push the cars garage door button. head unit should flash its light, letting you know that it is programed succesfully. genie units push 3 times

The green light on the motor unit is an LED and random flickering is normal. Your problem is most likely caused by an electrical storm or power surge. You will need to remove the logic board from the motor unit and check for burnt or missing traces on the printed circuit board especially around the small transformer. Your holding that button in will most likely have erased the memory of the unit and all your remotes will need to be programmed once you find your problem. I really suggest you call an technician at this point.

If the main light flashes 10 times when the door stops it is a door sensor problem. Make sure the small light on each one is lit and not flickering. If the main light doesn't flash you have either a bad IR sensor which is a small printed circuit board just in front of the motor or you need to increase the down force which is a control on the rear of the motor unit.

The LED flashing 5 times is the code for "RPM sensor or motor overload". Usually if it is the RPM sensor - which is a small printed circuit board just in front of the motor - it will run a few inches and then reverse. I doubt very much it is the motor. I would pull the logic board and check for loose or missing traces on the printed circuit. Especially if you have had any electrical storms or power surges.

Garage Door opened but will not close. I opened


I think the trolley has jammed against the bolt just in front of the motor unit. Remove the bolt and then run the door until it is closed. With the door closed locate the 'up limit' control on the side of the motor unit. Turn this 2 turns in the opposite direction of the arrow printed on the cover. Replace the bolt.

Garage door will not open


The light flashing 5 times is the code for RPM sensor or motor overload. The RPM sensor is a small printed circuit board just in front of the motor. I would really doubt it is a motor problem unless you have been operating the opener enough that the thermal overload protector has shut it down. It will start running again as soon as it's cooled off.

GARAGE DOOR OPENS AND CLOSES ON OWN LT BLINKS SEVERAL TIMES


Anytime a door opens and/or closes by itself I look for a smashed wire between the motor unit and the wall button.

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

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 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.

This can also interfere with remote controls

HOPE THIS HELPS
