I'm having an interesting problem with a Lionel Fastrack Command switch, left hand, O-72. This switch has been in use for about a year give or take and only recently did it start having problems. Initially it started acting up by sometimes not responding to the Legacy remote, but of greater concern is the new problem it's having now.
The new problem is the switch is throwing by itself, and when it does this it is to the diverging path instead of straight through. There doesn't seem to be any pattern to when it does this... It will happen if trains are moving or standing still, and will happen sometimes as a train is running over the switch. If it happens when wheels happen to be on the isolated rails it will immediately switch back to the through path like it should have been all along. But, if the timing is just right, it'll catch the trailing truck of a car and send it off to the side while the front truck is going on through - obviously causing a derailment.
I had the back off of this switch before when it initially started having problems responding to the Legacy remote and didn't note any loose wires or other obvious problems... Is the self switching behavior something that indicates a problem with the internal electronics or something else I need to look for, especially when also considering the intermittent lack or response to the TMCC signal? By the way, this is somewhat or a starter layout so it's powered by track power instead of separately. There are 4 other Command switches in use and they're all functioning normally.
Thanks!
