Chamberlain Security+ Model 6200 not working

[Slinah]

Hi - My garage door stopped working. Control pad on wall is blinking green, yellow light on motor blinks 5 times, stops, then repeats. When I press the opener the motor clicks. Anyone have any ideas?

5 flashes
This means the opener is not detecting any RPM's (rotations-per-minute) during the first second of operation.

Two plastic gears inside have been possibly stripped. There is a repair kit available. Been 17 years since I had the same thing happen. Kit was $15 and 30 minute job total.

I bought a gear for one for 4$. Was a little tricky to replace, 30 minutes sounds about right.
