My garage door opener stoped working after a storm.

My garage door opener quit working after an electrical thunderstorm. Is it a fuse in the motor assembly that I can replace or I'm doomed and I just lost about $350.00 and I have to buy a new one. The door opener info is as follows: Brand: Liftmaster; Model: 3280; Serial# 4745514201149; 120 V; Hz 60; 1/2 HP; Amps 60.

Why won't Chamberlain 1040-6 garage door opener open or close?


In addition to the ANT suggestion, are you able to open/close the door with the button first? And then check the 12-volt battery in the remote control.

Work-around: Modern cars have the ability to learn the motor's code. Then I use the built-in openers on my cars to open the garage door as work-around. All you have to do is initiate the learning process by pressing a button on the motor, and then keep pressing your built-in opener's button until the light becomes steady. Try to let your car stay as close to the motor as possible.

Good luck!

Try reprograming the opener to each remote, if this doesn't work then the command/radio module in the opener is damaged and needs to be replaced. Hopefully you can find one or you will have to replace the whole garage door opener. Good luck.

You have shorted out your logic board. This could of been prevented with a surge protector 900 joules or higher. Whether you repair or replace get one. Stanley went out of business but you may still be able to find replacement parts online. Thanks BB

Motor lift 2000. Have a problem the garage door will not open it just keeps going up and down it will not open all the way.


The problem may be in the door itself. Run it by hand to see if it is running well. Otherwise you can adjust up the force limits on the motor head. Do a 2x4 safety reversal test afterward. Thanks BB

I had a lightening strike at my home. Since then, the garage door does not function with wall switch or remotes. when i press the switch, light comes ON on the door opener and i hear a click but nothing...


Well, I don't think that disconnecting the garage door from the garage door opener would affect function.

The lightning strike could have destroyed the circuitry inside the garage door opener, seeing that it won't operate with the wall switch or remotes.

It's likely that a board was fried by the lightning which would render the garage door inoperable.

THEY CAN LOSE PROGRAMING IN ELECTRICAL STORMS OR POWER SURGES. UNPLUG THE UNIT TO RESET THE CIRCUIT BOARD.
REPROGRAM ALL REMOTES.
IF YOU STILL GET NO RESPONSE YOU PROBABLY HAVE A FRIED BOARD.
YOU CAN GET TROUBLESHOOTING INFO IN THE OWNERSMANUAL.
IF NOTHING ELSE WORKS CALL A LOCAL GARAGE DOOR REPAIR COMPANY. IF YOU REMOVE THE UNIT AND TAKE IT TO THEM MOST WILL DO FREE DIAGNOSTICS IN HOPE OF SELLING YOU THE REPAIR/PARTS/REPLACEMENT - BE SURE TO ASK IF THERE IS A CHARGE
HOPE THIS HELPS

on the back of your garage door opener there is a colored learn button--press and release-the learn indicator light will glow for a short time usually 30 seconds. within thirty seconds press and hold the buton on the hand held remote that you wish to operate your garage door. release the button when the motor unit lights blink. if you don;t have a light, two clicks will be heard. it has learned the code. procedure will be different for multi function control.
