My Craftsman Garage Door opener stopped working.

If when the door reverses the main light flashes 10 times you have a problem with the door sensors. Make sure they are pointed at one another and the small light on each one is lit and not flickering. They must be pointed at one another for both lights to be on. If you cannot get the lights to come on you have a bad logic board.

I would pull the logic board and check for burnt or missing traces on the printed circuit. Garage door openers hate electrical storms. I really doubt it got to your start capacitor.

If all else works, I'd start at the limit switch.

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.

Unfortunately there isn't a reset switch but I would pull the logic board and look for burnt or missing traces on the printed circuit board. Electronics do not like lightning.

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.

If you had an lightning storm you most likely have a bad logic board. That is not a reset button you are pressing.

Remove the cover and take a look at the drive gear. It sounds like it is stripped.

what openers? Sears/liftmaster of last 2 years have no reset. Sure power to outlet? Try a lamp. Did a gfi trip. Did wife run both doors to overheat them. they should cool off in 15 minutes. Do you have a surge protector. Did it go bad. Some kill power when they get cooked. Did you have a lightning storm. Culd have cooked logic boards.

Replace the opener
