SOURCE: Hi there. I have a Chamberlain Whisper Drive

I just had that problem this morning and the cause was that the springs that help hold the weight of the garage door were broken. This caused the garage door opener to raise the garage door a fe inches and then drop again. We called in a professional and $200 later we had new springs and everything works fine now.

SOURCE: door would not close all the way

DOES IT REVERSE OR STOPS BUT NOT TOUCHING THE FLOOR?

IF IT DOESN'T TOUCH THE FLOOR YOU EITHER NEED TO ADJUST THE DOWN TRAVEL OR LENGTHEN THE CONNECTING ARM.

IF IT REVERSES YOU NEED TO DETERMINE IF IT IS THE SENSITIVITY OR THE SAFETY EYES.

SOURCE: Adjustment of a Chamberlain WD822KL

The opener is having a hard time operating the door. It sounds like the door is out of balance. The door should stay all the way up at half down and all the way down. You should be able to raise and lower the door by hand EASILY. The opener is only meant to lift10-15 lbs. Thanks BB

You will have to open the unit and look inside it. Unplug it first. It should have 6-8 screws to take off. You will see 3 white plastic adjustment screws. There is a carriage they sit in. Make sure they are in this carriage. If you would like stay back a bit and plug it in and watch it run to see how it works. It is a direct contact system, so when the middle screw touches the copper limit of the limit screw it stops. Thanks BB

There is a button on the side of the wall-mounted remote. It has a pic of light bulb next to it. Press it once - the motion sensor is on and the lights will be on once it senses the motion; press it again and the motion sensor will be off.

My garage door opens about 6" then stops


It sounds like you need to adjust the force settings on your opener. You should see either a white plastic knob on the opener, or a screw adjustment labelled "Open Force" or "Open Sensitivity". If you adjust that, it should fix the problem. If not, you'll need to contact a repair service.

How do i set the travel limits on my craftsman garage door opener 139.53919


  • Open the garage dooricon1.png fully by pressing the wall control button. The bottom section of the door should be right at the header in the "full open" position. If it is too far back, the door cable can become misaligned. If it is not back far enough, you may not be able to get your vehicle in and out of the garage.

    Position a stepladder behind the garage door openericon1.png motor. Locate the limit adjusting screws on the left side of the motor housing. Have a friend stand by the wall control button.

    Insert a screwdriver into the slot for the "up limit" adjustment screw. Turn it to the right to decrease the door travelicon1.png and turn it to the left to increase it. Turn the screw in small increments.

    Close the garage door by having your helper push the wall control button. Notice the seal between the door and the floor--there should not be any light coming through. Adjust the "down limit" screw in the same way if necessary.

    Installed two new springs on automatic doorman model 455 and it won't close or open. chain will not move door where are adjustment screws? I think that may be the problem


    Does it make a noise? Did it run before you changed the springs? Did you replace springs on opener or on the door? What adjustment screws are you looking for? Do you think they went out of adjustment when you changed the springs?

    Craftsman 1/2hp garage door opener does not go down to floor


    I'm no expert, but on a previous door opener I had (don't know the brand), the side adjusting screw basically adjusted a limit switch, which was located inside the plastic housing (where the motor is). I was able to remove the housing, figure out which limit switch was actually being contacted "too soon" on the way down and adjusted it while watching it.

    Just a suggestion, you might take a look.

    just keep your hands out of the way of the chain and sprocket if you do take the housing off. .

    Garage door opener chain out of sync with door


    There are two white screws on the sides that adjust the limits. Adjust the "down" screw less. You should have to turn the screw 4 full turns for eight inches. After you make this adjustment, test it without the door being hooked up to prevent damage to the door or opener if it tries to close too far.

    There are two limit adjustments on the opener. usually the screw show which way to turn if the door needs to be lowered more or raised more. Turn them only about a1/4 turn with each adjustment.

    You need to re-align the drive belt - it thinks it is in the raised position, with the door on the ground.
