Look at your manuel find the page that shows the limit access switch. (Unplug your opener.) It isn't really a switch, but the three white plastic screw like parts. The center has a brown wire connected to it, which has a metal piece that is as wide as all three white screws. The outside screws are your limit access stop guides, one for the up control stop guide and the other for the down control stop guide. If the center screw with the metal part gets caught behind on of the stop guides the motor will not engage. Gently move metal piece from behind the stop guide.

The unit is in the lock mode, push and hold the lock button in for about two seconds and the green LED should stop flashing. Your remotes should work.

SOURCE: Door won't close, blinks 10 times, sensor light yellow

Anytime the main light flashes 10 times and the door reverses to the open position it is a door sensor problem or the wiring to them. Nothing else causes this symptom.

To answer your question the opener is in vacation mode. Press and hold for 3 seconds the button on your wall control with the lock icon. The green light will stop flashing and you will be back in business.

You need to hook those wires back up and then check the door sensors very closely. If the light in one of the door sensors is dim or flashing it will cause your problem.

The wall control unit is flashing but it will close and open the garage door, but when I press the remote from the car the light flashes twice and it will not shut the door.


You may have 2 problems here. First press and hold the lock button on the wall control for 3 seconds. This should stop that flashing and your remotes should work. If the main light is flashing when you try to close the door you need to check that your door sensors are pointed at one another and the small light on each one is lit and not flickering. Tweak them a little.

On the end of your opener where the small gray antenna is you will find an LED that flashes rapidly when you use your remote. When you release your remote it should stop flashing rapidly and just occasionally flash. See if this continues to flash rapidly while the bulb is on and your remotes are inoperative. If it does, remove the bulb and do the same thing. I have a feeling your light bulb is radiating.

Sears garage door opener 1/2 hp about 6 years old. Will not respond to remotes to open and close. Light flashes on opener when remote is pressed but no door action.


Door sensors are not working. Check if lights are on both sides.
Might be misaligned or one is bad.
Door will close if you hold in the garge close button until it's all the way down.
And it will open on it's own.
You can get these off ebay.

Programming remote, unit will not flash.


The easiest way to program is to hold the button on the remote while you press and immediately release the smart/learn button. If it worked before there is no reason for it not to work now unless it totally failed.

Reprogramming remote and key


if its early 05 round heart shaped remote it needs programming into system at dealer with Tech2
later 05 to 07 had square (rectangle) shaped remote
1.2 ID Code Additional Registration
Note: This procedure will add additional remotes to the Keyless Entry Control Units memory. A total of 4 remote transmitters may be programmed into the Keyless Entry Control Units memory. When a total of registered and newly registered remotes exceed 4, the oldest one shall be erased.
Step Action
1 Note: Make sure that all the doors are closed and unlocked. Insert the ignition key into the ignition switch.
Open the driver's side door.
2 Turn the Ignition key to the “ON” position and then to the “LOCK” position three times
(The key should remain in the “LOCK” position)
Note: This step must be carried out within five seconds.
3 “CLOSE” and “OPEN” the driver’s doors once (Leaving the driver’s door in the “OPEN” position)
Note: This step must be carried out within five seconds after step 2 is completed.
4 Wait for 8 seconds (This wait time is critical)
5 Turn the Ignition key “ON” and then to the “LOCK” position once and turn key to the “ON” position (The key should remain in the “ON” position)
OR on/lock once
Note: This step must be carried out eight seconds after step 3 is completed.
6 “CLOSE” the driver’s door
The HAZARD lights should flash 3 times (This acknowledges the Keyless Entry Control Unit has entered programming mode)
7 Operate the lock or unlock button of the transmitters to be programmed; a flash of the HAZARD lights indicates the remote has been successfully programmed into the control unit
8 The HAZARD lights will flash approx 4 seconds after pressing the remote button to indicate the Keyless Entry Control Unit has exited programming mode.

Grage door blinking yellow, click and won't open with anything.


TRY RESETTING THE UNIT BY UNPLUGGING IT FOR ABOUT 5 MIN.

IF WHEN YOU PLUG IT IN THE REMOTES STILL DON'T WORK TRY TO REPROGRAM THEM.
IF STILL HAVING TROUBLE--
COUNT THE FLASHES - GOTO LIFTMASTER.COM DOWNLOAD A FREE PDF FOR A SIMILAR UNIT (THE MODEL NUMBERS ARE DIFFERENT BUT THE CODES ARE THE SAME).
HOPE THIS HELPS
