How to keep the garage door lighe on for less time


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

Overhead light will not come on when door is opened


Press and hold the Lock button until the light blinks (about 10 seconds). A single blink indicates that the timer is reset to 1 1/2 minutes. Repeat the procedure and the light will blink twice, resetting the time to 2 1/2 minutes. Repeat again for a 3 1/2 minute interval, etc. up to a maximum of four blinks and 4 1/2 minutes.

Sounds as if you have inadvertently turned on the vacation lock. If you have a lock button hold down for two seconds to turn off. Then your remote should start working again. May need re-programmed if you left the battery out for more than a minute or two.

Overhead light stays on all the time on craftsman garage door opener


Hello. If the light stays on all the time check these:
A. The light time delay on the opener will keep the light on for approximately 4-1/2 minutes after the system has be activated, then will turn the light off automatically.

B. If the opener has a worklight switch (which is supplied only with a four-function wall console), slide the switch to "OFF" position.

C. If the opener has a pedestrian switch (which is supplied only with a four-function wall console), the light will stay on for 4-1/2 minutes after the pedestrian door has been opened.

When our garage door opens, my light turns off immediately. How do I get it to stay on for about 5 minutes?


Try this:

Press and hold the Lock button until the light blinks (about 10 seconds). A single blink indicates that the timer is reset to 1 1/2 minutes. Repeat the procedure and the light will blink twice, resetting the time to 2 1/2 minutes. Repeat again for a 3 1/2 minute interval, etc. up to a maximum of four blinks and 4 1/2 minutes.

The light stays on for a long time although it shuts off (a lot more that 4.5 minutes). Can this be adjusted to be shortened? Where and how on the unit?


If you have one of the newer models the duration can be changed by holding in the lock button until the light blinks (about 10 seconds.) A single blink indicates that the timer is reset to 1½ minutes. Repeat the procedure and the light will blink twice, resetting the timer to 2½ minutes. Repeat again for a 3½ minute interval, etc. up to a maximum of four blinks and 4½ minutes.

If your opener has the motion sensor feature and a person enters the garage and walks in front of the door control the light will come on for 5 minutes and then shut off.

Liftmaster garage door openers Model # 3245 (remote Issue)


it is possible that when you programmed the car remotes you erased the pairing between your hand held remotes and the unit. Follow the instructions to pair the remotes again and you should be good to go.

I have 2 liftmaster 3245. The hand held remotes were working fine then stopped. I replaced the batteries and turned of all electrical/RIF close by. Still not working. Both cars operate the doors with no...


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.
