    I also have a Chamberlain Whisper Drive garage door opener and the red light blinks twice but it only opens if I hold down the wall mounted button. I have tried changing sensors, sensor wires, taken off the control board to see if it had an issue, but nothing works... Help.

You wall control is in lock mode sounds like press and hold the lock button for 3 to 4 seconds that should take care of that problem.

Alleejr your problem is not the same and ill need little more info. Where is the red light on your wall control? If its on the way up its not your sensors at all. Is your spring broke?

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 my garage that could be setting off the motion sensor. What could this be?

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.

Try programming this way. Hold the button down on your remote and then press and immediately release the smart/learn button. If this doesn't do it your remote may be bad. The wall control is hard wired and doesn't use the receiver that your remote does.

Chamberlain remote has stopped working, new


WHEN YOU CHANGE THE BATTERY NO NEED TO REPROGRAM THE REMOTE.
THE FLASHING LIGHT TELLS YOU IT IS SENDING A SIGNAL THAT IS BEING RECIEVED IT IS JUST NOT THE CORRECT CODE TO OPEN THE DOOR.
REPROGRAMING THE REMOTE SHOULD SOLVE THE PROBLEM

One sensor should always be yellow, the other should be SOLID green.
If the lights are not consistently SOLID, you have a sensor issue.
TEST: If the door closes completely by pressing and holding down the wall pad button, you have a sensor problem.

Check to make sure the are aimed properly at each other.
Check the wire at the sensor and more importantly at the machine (If the wires are loose at the machine (terminals) it can cause this problem. Remember the machine does shake a lot.
If the wires are good, the sensors are aimed correctly, you have a sensor issue and need to loacte a replacement set.
