Chamberlain makes a surge protector that is made specifically for their openers. I would try one of those. The part number is 990LM and should be available from any service company in the yellow pages that advertises Chamberlain or Liftmaster. Unfortunately as you have learned, lightning loves logic boards.

Press and hold the lock button for 3 seconds.

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.

There isn't a reset button. Check the house circuit breaker. You may have had a power surge and that can damage the logic board printed circuit. Check the logic board for missing or burnt traces especially around the small transformer.

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.

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.

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

Your opener has been hit by lightning or power surge.
If it's not too old you can replace the 'back board' (the computer board on the back of the opener.) Also If the opener has safety sensors one or both of them may be burnt out too, and if it was really bad then the rpm sensor will go too. So you could be looking at paying half the cost to repair or just get a new opener. Up to you, and get a surge protector. Lift master has a good line of products and makes thier own surge protectors for thier products.
