Nope, can't just buy the gear. Same failure mode as my last one and I also could not believe how completely cheap that gear was. But hey, it's "MADE IN FRANCE" so no wonder it's crap.
Make sure you save the rod that runs from the solenoid to the latch, because it is a seperate part.
Unfortunately, I no longer have the P/N handy. Bill Jenkins got me my replacement while still at his old job. Ran about $60 with shipping. It's starting to act up in the same way from time to time.
