The liftmaster garage door openers manufactured after 1984 are set through the logic board from the factory with a setting of 4 1/2 minutes, That setting cannot be changed manually but you can by a premium wall control console that lets you override the logic board settings by simply pressing the light function button that allows you to shut the lights off earlier by simply pressing the button or also you can keep the lights on indefinitely by pressing the button twice! The lights will automatically go back into the 4 1/2 minute mode once the door is operated in either the up or down motion. Hope this answers your question! P.S. The premium console comes with a safety vacation lock also and can be purchased through Ebay or through Liftmaster....Remember the Liftmaster name also make the chamberlain brand and the Sears Craftman openers ...They are all cross compatible on the Premium wall console and have 2 wires on them to hook up (low voltage ) so don't worry you won,t get a shock! Just match the red wire to the terminal marked red and the white wire to the terminal marked white and screw onto your wall! Good luck .Glenn

Nothing wrong with the sensors. They don't work when the door is opening anyway. Only when closing. Make sure the light in the wall control is not flashing. If it is press and hold the lock button for 3 seconds.

The main light flashing 10 times is the sign of a door sensor problem. Check to see if the small light on each sensors is lit and not flickering. If you cannot get both lights to come on your sensors or the wiring to them is bad.

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.

It could be a bad logic board especially if you have had any electrical storms in the area. I would remove and check the logic board for burnt or missing traces on the printed circuit board.

Press and release receiver button.

Some craftman operator don't have that feature. Are both photo eye lights green? Feature not available. If the photo eyes are yellow and green feature should be avilable. The operator needs to have a three button wall station. With the light on the operator off press and hold the "light" button for about a minute until the light flashes.
