Question about Chamberlain Powerdrive PD422D 1/2 HP Security Plus Screw Drive Garage Door Opener

1 Answer

Whisper Drive not working

As of today my Whgisper Drive unit will not complete an open or shut cycle. It starts when the remote, or keypad is used, then after 2 seconds it stops and the lights on the unit flash for 4-5 seconds. The lights stay on.

    Problem was fixed. The safety beam at the bottom of the door was out of alignment and the door would not close. As soon as I realigned the beam, PRESTO, the door worked perfectly.

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

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.

i think what is happening is the code in your open has a list of different codes it cycles through to keep someone from "capturing" it and opening the door when you gone.Try having someone help you and program the three units at the same time.

Garage door goes up but will not go down.


UNPLUG THE UNIT AND WAIT 5 MINUTES.
THIS WILL RESET THE CONTROLS.

SEE IF THE WALL BUTTON LIGHTS UP.

IF THIS DOESN'T SOLVE IT GOTO CHAMBERLAIN.COM AND DOWNLOAD THE MANUAL (FREE PDF FILE) IT WILL TAKE YOU THROUGH A COMPLETE DIAGNOSTIC.

HOPE THIS IS HELPFUL

Chamberlain garage door opener unit-is it compatible with craftsman keypad?


Hello,Linda well this is your lucky day ,I have installed garage door openers for sears for 10 years and i can tell you that craftsman,chamberlain ,and liftmaster are all the same machine and manufactured under the liftmaster name , if you buy it from home depot it will be a chamberlain ,if you buy it at sears ,it will be a craftsman, and if you go to commercial building supplier it will be a liftmaster! now getting that out of the way even though they are all compatible ,there is one thing that stands in their way and that,s time ,For example if your chamberlain machine is 5 years old and you went to sears last week ,the chances of the frequency being the same are not good , most likely you have the wireless keypad , one way to test the sears keypad against the chamberlain machine is to locate the smart button on your machine ,this button allows for programming of remotes and keypads , to test and see exactly what im talking about take your remote and locate the smart button ,if you have three buttons on the remote press one of the buttons that are not being used on the remote ,above the smart button their will be a blinking light ,if you press your remote button you will notice the light go from a blink to a rapid flash , This is telling you that you are sending a signal for programming to the machine , well the keypad is exactly the same all you have to do is push the enter button on the keypad and have someone watch for the rapid blinking light ,if they are compatible the light will blink rapidly on the machine so all you have to do now is have someone press the smart button once on the machine your indicator light will now be a solid light you will have approx 60 seconds then to put a 4 digit code in the keypad and then press and hold down the enter button on the keypad , at this point you will notice the lightbulbs on the chamberlain machine to shut off and come back on this is to tell you that the machine accepted the code , after thats been done you can use your keypad , you can also find the owners manual to the chamberlain and follow the same instructions to programming the remote , they are identical in programing , if your keypad is not the same frequency you can also tell by looking at the frequency code on the backside of the keypad and also the chamberlain unit usually where the light bulb is will be its code

My Chamberlian Whisper Drive 1/2 Hp opener has an issue. My motion sensor back light blinks and the factory supplied remote does not work now. 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?

Garage door opener doesnt close the garage


If you have to hold down the button to close the door, you are bypassing the sensors ...
Check the alignment of the sensors. Should see a solid GREEN light
