So, this morning I called the help line. Of all of the help lines I have used over the years, Mighty Mule employs, quite possibly, the rudest and least helpful associate I've ever dealt with. I really want the latch to work. More later after I find the solution.
After some reflection on the unsatisfactory call to the helpline, I called for a Mighty Mule supervisor later in the afternoon and got two! They were very helpful with both the employee situation and my original latch problem, although the problem is not quite solved, as I ran out of time to work on it. The secret appears to be balancing the Stall Force and the Closed Position Limit settings.
The lock works well, and the only installation issue I encountered was also described by another reviewer. If your gate closing position is set too short (e.g. even with the gate post, instead of just slightly past it by maybe an inch or so), the gate can "bounce" away from the latch, allowing the solenoid to close outside of the latch. Just set your closing position so it "holds" the gate firmly against the post/stop latch when it closes.
I did have one problem with the lock after several months of use. It began sticking open, whereby the solenoid would release the lock plunger properly as the gate closed, but the plunger/latch wouldn't actually close due to being stuck internally. I couldn't see how to fix it without disassembling the lock, so I called Chamberlain. They have great customer service, and they promptly shipped me a replacement. Now I have the old one as a spare, assuming I can fix it after taking it apart.
Anyway, whichever version of this lock you buy, I'd give it a good rating. It's a fairly basic device, and a bit overpriced (I found mine on ebay from someone who bought it but never installed it, and saved big; but that was just luck). But it does the job.
I am in agreement with the most critical review above. I found the same problem in that the lock released on OPEN and before the gate moves away, the lock CLAMPS the pin before the gate can open. It only releases the pin for about TWO seconds and immediately CLAMPS. I had previously installed a nylon shear pin instead of the steel pin so no damage occurred when the lock CLAMPED the gate closed while trying to open. I disabled the soft start feature hoping that the gate could move out of the lock before it CLAMPED back. I found that if you disable the soft start, the lock only OPENS for about than ONE second. This could easily be fixed with a change to the PROGRAMMABLE CHIP that controls the whole gate, but Mighty Mule has not listened to any feedback to correct this problem. I am surprised that more people haven't reported this same problem. I am able to engineer around this problem with a DELAY ON RELEASE RELAY, but how many homeowners would be able to do this? Should be ZERO stars.
Twenty four hours later--Built a six second delay on RELEASE, meaning that the lock stays open for six seconds as the gate opens, and the lock works perfectly now. Also, when the gate reaches the stop post, bounces around a bit and then settles down, then the latch closes. On OPEN, the latch stays open until well after the gate moves away. This is the kind of simple fix that our software people do on a regular basis. Oh, and I triple protected the PCB from spikes from the large solenoid that releases the latch. I am reasonably sure that many of the failures that occur with this lock can be attributed to the large back EMF spike that the miniature relays can't handle. The lock is WELL MADE and FINISHED WELL and I expect never to have a problem with this lock. With a simple SOFTWARE fix, this would be 5 stars.
