SOURCE: Garage door doesn't open or close

You should check the gears inside the box, After years , the gears get dry and die, you can by online or from Sears the kit and replace the old gears. I just changed mine...not too difficult :) .

You probrbly need to replace the gear and sprocket kit inside the opener. Also make sure the trolly is not disengaged. Tug the rope!

SOURCE: Chamberlain Power Drive 1/2 HP - motor runs but does not move chain

I have the same problem with the worm gear shaved. I bought the replacement part and replaced the worm gear. The door did not travel to the full distance between the limit switch. It hit the upoer limit, stopped. When I pressed the remote again, it only reverse for a short distance and never hit the other end of the limit switch. Any hints what the problems are?

Door wont close

The gear wheel powering the chain is stripped. The cogs are usually plastic and not uncommon for them to wear or break off. Replaceable item from manufacturer.

The yellow light on main unit flashing ,there is power can here the opener click but wont engage ? from main control and remotes

Be sure the level that the release rope is connected to is pointing towards the motor unit, and raise/lower the door to the position of the inner carriage, so that they will engage. If the inner carriage is fully closed and will not move to the open position, or still will not connect with the outer carriage, you will need to have the opener serviced.

I have a 1/2 HP Whisper Drive. The lights are not working. I have replaced the light bulbs, and I can hear the relay clicking, but the lights do not come on. Other than this, the system operates...

Are you using the newer energy-efficient light bulbs? Most of the problems I have encountered are related to the newer bulbs. Sometimes they just do not make a good connection for some reason. If you are using the older-style bulb, try cleaning the contact points (with the opener unplugged of course), they can sometimes accumulate gunk.

Otherwise, it could be a loose wire- or bad receiver board. Just to make sure, though, definitely try a number of new bulbs to be certain that the bulbs are good.

Also, make sure you check the balance of your garage door, to make sure the springs are properly counter-balancing the weight of the garage door. Otherwise, the opener will work overtime and not last as long. You can see a how-to video on our website.

My chamberlain Whisper Drive HD600 garage door opener Light's click but do not go on. The door is working fine.

Probably just a burned-out light bulb. The "click" you hear is the relay closing. Replace the bulb. *Disclaimer: I am not a lawyer, despite the handle.

If the wall button will operate the door up but none of the devices do then look at the wall button. Find the lock button and push it for 2 seconds and then try the remotes again. This is your vacation lock. You can get a manual at Now if the door does not open or close with the remotes you can reprogram them. Press the colored learn button on the motor head and then press the button on the remote. Repeat for each remote. If they fail to program you will need a new logic board. Thanks BB

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.
