Sears 1/2hp thinks it is not all the way up and will not go down

After some storms I opened the garage door and it went up fine, tried to close it and nothing happens. It just makes a clicking noise, the gears, and everything mechanical is working properly- Is it the logic board that needs to be replaced? Sensors are aligned I can stand between them and hit the button and the lights flash on the opener.
Can also manually lift door.
Any help appreciated
thanks
kevin

It is really a common problem for lightning or electrical surges to take out the logic board. Big expense too.

Champion Liftmaster Garage will not open or close. Just clicks
Pull the logic board and check for burnt or missing traces on the printed circuit. I would guess at an estimate of $125.00 but don't even know where you live.

Remove the cover from the motor unit and check the drive gear. It is a white nylon gear just in front of the motor. Also check the door springs. One of them could be broken.

Garage door not opening properly.
Check the springs on your garage door. If one is broken, the opener will not have enough power to raise up and it will stop like that.Or the up and down limit settings have gone off or bad.

Garage door opener closes when closed
Try this: Loosen the chain enough that you can remove it from the sprocket above the motor. Now run the opener until the sprocket turns in the clockwise direction and stops. Reconnect the chain. This will get everything in sync and you will have to tweak the 'up and down limits' a bit to get it just right.

No reponse when using the remote, the wall control works fine.
The remotes use a receiver to actuate the door and the wall control does not. It sounds like your logic board is bad. Maybe a lightning storm recently? Try removing the board and look for burnt or missing traces on the printed circuit.

Craftsman Garage Door Opener won't work after storm
Check to see if the trolley (the part that slides back and forth on the rail and is connected to the door) is jammed against the bolt just in front of the motor unit. If so, remove the bolt and run the door until it is closed. On the side of the motor unit there is an 'up limit' control. Turn this 3 turns in the opposite direction of the arrow printed on the cover. Be sure to replace the bolt.

Garage door opened, won't close
If you can press and hold the wall button and the door will go down, you have a photo eye issue. Check the photo eyes at the bottom of the door.
