    both lights don't come on. I hear the sensor click when motion is detected. I changed both light bulbs but still it does not work. Is there something that I can do for an easy fix? thanks in advance.

If you have a Craftsman/Liftmaster with a 3 function wall control:
use the lift button to turn the light off. push and hold the light button for @1min. until the light flashes. This should reset your operator to have the light turn on when you walk through the photo eyes.

I have a baffling issue with my Chamberlain whisper drive. I have noticed that in the middle of the night sometimes the light on the opener comes on for a few minutes. There are no rodents or anything in...


MOTION SENSORS WORK BY MEASURING TEMPERATURE.

ANY TEMPERATURE VARIATION COULD CAUSE A FALSE ACTIVATION. LOOK FOR ANYTHING IN SIGHT OF THE MOTION SENSOR THAT CHANGES TEMP.

ALSO SOME UNITS TURN ON THE LIGHT WHEN THE SAFETY EYE BEAM IS BROKEN.
YOU COULD HAVE AN INTEMITANT OPEN CIRCUIT OR SHORT (USSUALLY UNDER A STAPLE) CAUSING THE LIGHT TO AVTIVATE FOR ABOUT 4.5 MIN. I HAVE ALSO SEEN SPIDERS MAKE THE HOLE WHERE THE EYES ARE A NICE HOME THIS WILL ALSO TRIP THE EYES.

HOPE THIS HELPS

Check engine light


BMW engine light

Comes on if DME engine management system self diagnostic fault detected. Will stay on until codes are called up and memory erased.

With OBD read the code as follows. Turn on ignition key, press accelerator pedal to the floor five times within 5 seconds. The check engine light will remain on for 5 sec , blik off, come on for 2,5 sec, go off for 2,5 sec and fault code will begin to flash. If more than one fault exist 2nd fault code will be separated by 2,5 sec pause. after fault codes there will be a 0.5 sec flash and light will remain off. to read codes again do procedure again.

Canceling of codes. make sure fault code is present (short blink and light goes out for long period), depress throttle pedal for at least 10 sec. read fault codes again and check for code 1444 (no faults stored.)

Check also the following, fuel pump, oxygen sensor, fuel injectors, engine coolant temp sensor, idle speed control valve, mass airflow sensor and too many other things.

Remote does not open or close garage door; inside button flashes


What has happened is that you electric eyes are blocked or have gone out. The eyes are at the garage door about a foot of the ground on both sides. There should be a red or green light on one of them. If not some thing is blocking the beam that goes across the door. It is a safety beam so kids can nt get hurt when the door is coming down. If the beam is broke the door will go back up.

Whisper Drive not working


Why not call Liftmaster on 800 number. I can see a problem going down with safety beams, but not up.

Chamberlain door will not close, despite down force set to max


Problem solved, sort of-
My unit has self diagnostic capabilities: next to the remote sync red button, is a yellow light the indicates diagnostic readings by blinking. In my case the light was flashing 5 times after the door failed to close. This meant RPM sensor failure. I rechecked the sensor and "flywheel" cap and found that it was not completely secured. With the "flywheel" in the proper position, providing readings for the RPM sensor, the door completely closed.
But my yellow diagnostic light is still flashing 5 times. My door is operating correctly, but the diagnostic feedback is still not completely happy with my RPM sensor. So I will keep and eye on it.

Garage sensor problem


The colour on the sensors doesn't change.
One is orange constantly and the other is green when detecting a signal from the orange sensor.
If the green is flickering, they are not adjusted correctly.Move the green sensor until you get a good solid green. Holding the wall pad button down, just bypasses the sensors.

Try adjusting only the sensors so that they are solid.

In addition, check the little yellow light on the back of the machine and count the flashes.
The number of flashes will tell you what the error is in your manual.

Door ups and downs


Holding the button down just bypasses the sensors.
Your sensors are not adjusting correctly, or there is a short in the wires.
The back of the machine has a little yellow light, count the flashes and corelate it to the troubleshooting portion of the manual to confirm.

The orange light is a constant, the green sensor needs to be adjusted until you get a solid green light.

Door will go down only if i keep button pressed


This is what we call in the buisness a constant hold down , that means that the sensors are not aligned , be careful when checking theese sensors because even the slightest flicker will send a false signal to the opener and not allow it to come down , I have installed over 27 thousand ..yes thousand machines to date and i,ve seen it all also make shure the sensor lenses are free of dirt or cobwebs , so now you need to check theese things and also if you realign the sensor and you only have to do one ! make shure you have a steady solid light, is their is a short in the wire ,you should splice a new wire in its place black to black and white to white as they are color coded universaly, also check for brooms and shovels and the typical junk that people usually put in the corners of the garage ,i,ve had many service calls and just had to move a broom that was in the way of the sensor , the beam must be unobstructed and the lights should be bright and solid without any flicker , also green light is the sending unit and the yellow light means it,s the recieving unit on your sensors , Hope you have luck and i was able to help you ,thanks so much for the questionSincerely glenn

Door won't go down


Yes ,your path may be clear and you might have two indicator lights lit,but remember that theese sensors are called a sender and a reciever,the sender send,s a signal to the reciever to let it know that alls clear and their are no obsructions , but i can tell you from experience that if your sensor has the slightest fliker it will not allow the door to come down as a safety feature that was incorporated in all machines by law from 13 years ago, First thing you want to do is find out which sensor is the reciever and this is very easy ,Just put your hand in front of one of the camera,s ....The one sensor that,s light goes out is the receiver, Thats because it is not receiving a signal ! Now I want you to make shure it is straight in it,s holder,aiming directly accross from the other sensor! Next go to the sender ,This beam is the crucial one and must be directly pointed at the reciever, notice the light on the sensor it is always solid and will not go out ,Next i want you to go back to the reciever and loosen up the wingnut that holds the sensor in the bracket , as you move the sensor up to down and left to right notice the light on the receiver become dim and bright and flicker as you move it from the direct path of the sender , this is exactly what i want you to adjust to it,s brightest light possible , after you have tightened it back up go over to the wallpad or doorbell that operates the door and see if your problem has now dissapeared , Thank you for letting me try to help you and hopefully we fixed together Sincerely Glenn Mayer
