Theres 3 possibilities. #1, the door is disengaged from the motor. To fix, for a genie screwdrive, pull red cord toward the opener motor until it clicks in place. For most belt or chain drives, pull the red cord toward the door until theres a click. Release, try to manually lift door half way then hit the remote. If this is your problem, it will reconnect and youre good to go. #2, the capacitor is faulty. Symptoms of this are the motor makes a short buzzing sound then stops. You may also hear sizzling or see "smoke" (which is really vapor) coming out of the motor. Capacitors are cheap so if youre comfortable, take the lid off the opener you will see capacitor mounted to the top. Match the #'s off the old one and find a new one.UNPLUG THE UNIT BEFORE REMOVING THE LID! If you are not sure what a capacitor is, this task is above your skillset. #3 you have a gear stripped. For genie screw drives its a coupler which is internal call genie for instructions and parts. If its a belt or chain drive, the gear/sprocket assembly is stripped and you should consult the mfg for parts and instructions. Its definately NOT a circuit or logic board problem.

Thats one of the symptoms of a lightning strike or a power surge. Without actually being there I would suggest replacing the back-board. But as with lightning strikes and power surges sometimes other electronic components could have been damaged as well.

Most likely your door sensors have been bumped and are not aligned properly. Make sure they are pointed at one another and the small light on each one is lit and not blinking.

Remove the cover and check the drive gear. It is white nylon and is just in front of the motor. The part number is 41A2817 and is available from Sears or any good door opener service company. It comes with instructions.

See if the trolley is jammed against the bolt just in front of the motor unit. If so remove the bolt and then run the opener until the door is closed. While the door is closed locate the 'up limit' control which is on the side of the motor unit. Turn this control 2 complete turns in the opposite direction of the arrow printed on the cover. Remember to replace the bolt.
