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.

The motor has a thermal protector that will cause the motor to quit when it gets hot. If you let it cool off it will automatically reset and should work again.

The motors in a garage door opener are under quite a strain and will not run too much without overheating. The thermal overload will cut them off until they cool. This could be your problem. The model number of the opener is on the end of the motor unit nearest the door and you need that to make sure you have the right keypad. There are more than one and some will not work.

There is no fuse in your opener. The logic board is very susceptible to power surges. You can pull it and check for burnt or missing traces on the printed circuit.

TRY TO REPROGRAM THE REMOTES TO THE OPENER - THESE UNITS CAN LOSE THE MEMORY DURING STORMS.

I WOULD SUGGEST ADDING A SURGE PROTECTOR AT THE PLUG IN TO PREVENT DAMAGE TO YOUR UNIT IN THE FUTURE.

You have a stripped gear on the opener. Take off the cover on the motor. The bottom of the cover will be filled with white shavings. You can repair this with a "liftmaster gear and sprocket assembly".
