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

Chamberlan 1/2 hp security + not working

Hello Guys:

My garage door open was working perfectly, until the chain came off the track. I put the chain back on the tract and now the garage door opener track goes forward as opposed to backward (so the opener tries to push the door down into the pavement as opposed to trying to open it) and then goes back to its original position..
I have tried resetting the system, tinkering with the up and down dials but nothing works..

ps any suggestions wouyld be great.

thank you
Ian

Try
take the chain off
push the remote so that the motor turns and stops
then reattach the chain

sounds like you put the chain on with the door in the opposite position

Cannot open my garage door manually after I disengage it from the garage door opener (chain drive)


They are not light weight but there is no reason if the motor can raise it, then you cannot raise it by hand.

Garage door moves few inches and stops, springs are fine, sensros are fine.


If it is not blinking when it stops, then the capacitor is blown. Replace the capacitor and it should resolve the problem.

My Chamberlain 1/2 HP will occasionally only open the door half way, forcing me to manually open and close the door. But then it will suddenly begin working again all on it's own. What can I do abou


most likely there is a safety overload switch that will stop if the rollers on the track ( the steel that the door rolls in) is dry and needs to be greased so it can roll in the tracks freely also check the chain for the same, the chain drive should be free of any junk stuck on it ,the chain should not be to tight or twisted in any way, if it seems to be leaning one way or the other twist it straight with a pair of pliers also be sure its power source is not share with any other appliance. let me know of your progress.

Motor runs but door won't open. checked chain, seems to be ok


Hello,

The problem is not the chain, it is the plastic gear in the unit of the liftmaster Garage Door 1/2 Hp.The plastic gear is not engaging, although it sounds like it is working.

You will have to replace it with a new one, then the liftmaster Garage Door 1/2 Hp will be able to open up once again.

Once you open and remove the old gear, Be sure to thread the screws in all the parts before you install them. Pre-threading them once would really help. Secondly, label the wires on the back of the opener before lowering it to the ladder, so you can put them back in their proper place.

Hope this was helpful.
Goodluck

My chamberlan garage door opener keeps beeping


The only thing on a chamberlain garage door opener that can beep is the battery back up unit. It beeps if it is being used or if it has lost it's charge or if it has lost the power to be charged. There is also an led light that will give you information on the status up by the battery too. These will be in your manual to decipher. You can get a new battery at chamberlain.com Thanks BB

Garage door opener... goes one way but the other way it clicks....?


It clicks because there is something obstructing it. It is designed to give way as a safety feature. Examine the chain and track along with the sprocket to the motor where the chain connects and look for obstruction of some kind.

Replaced sprocket and worm gear on chamberlain 1/2 opener


The easiest way to fix this would be to take the chain off the sproket with the door and the trolley in the down position. Next hit the wall button and pay attn. to weather the gear is turning clockwise, you want it to turn that direction, wait until the unit stops by itself, next put the chain back on and now you should be able to adjust the limits. otherwise you should call a local professional. They will usually service your door as well as fix your opener.
