SOURCE: Chamberlain Whisper garage door system that only closes 3/4...

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.

My garage door will not open, the door gets close to the ground, then back up again. one sensor is green and other one yellow color. Please help me. My email- frooty2cute@yahoo.com


LUBE THE SPRINGS AND ROLLERS WITH WD40.

WATCH THE SENSOR LIGHTS TO SEE IF THEY GO OFF JUST BEFORE THE DOOR CLOSES. IF THIS IS THE PROBLEM EITHER ADJUST THE TRACK OR MOUNT THE SENSORS TO THE WALL INSTEAD.

IF THE SENSORS STAY LIT AND THE DOOR STILL REVERSES AFTER LUBE. ADJUST THE DOWN SENSITIVITY ABOUT 1/8 TURN AT A TIME (LESS SENSITIVE) ID YOU HAVE TO ADJUST THE SENSITIVITY MORE THAN 3/4 YOU WILL NEED TO CALL A PRO OUT TO CHECK THE PROBLEM.

HOPE THIS HELPS

My garage door will not close. The door gets close to the ground, then starts back up again and when it gets to the top the lights flash.


Just got off the phone from one of the rep's of Chamberlain...Go to the sensor that is blinking(it should be the one with the green light) loosen the sensor until the light goes out, then tighten it back up until the light come back on, and push the garage door opener. it should reset the unit.

Upon pressing open/close button kitchen door the garage starts to close but then reopens after 3-4". one must then hold button until door is fully closed. what is remedy?


The problem is that your system does NOT "see" the safety "eyes" sensors. Make sure that your sensors are properly connected to the opener (both sensors should have lights on them, one amber and another green). If they do not, check the wiring and the connections at the opener itself.

Chamberlain garage door will not close


See if both sensors stay lit until the door reaches the closed position.

If either light is off or flickers the door will go back up. Try aiming the eyes very carefully. If they are aimed properly. Check the wiring if you move the wires and the light flickers you have a bad connection. If the lights don't come on you may have a broken wire.

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.
