Why would my Fastrack switch start buzzing?

Try throwing it one way and rolling a car through it the opposite to activate the nonderail feature. Try this with it set through, and on the diverging route.

The last time I had a similar problem, the switch mechanism was not fully activating the microswitch controlling the non derail feature. This was making the switch "think " it needed to be thrown, so it buzzed because it was still trying to turn the already turned rails.

If rolling a car through the switch opposite of the way it is turned does not activate the non derail feature turning the points in the correct direction it could be the same issue.

That didn't work - tried it a few times.  Still buzzing!

I had one that acted just like yours.

Never did figure it out.............put the offender under the train table and put a new one in it's place.

Problem solved.

..at $90 a pop, I'd hope to find a way to fix it! But, I suppose if all else fails, yours is the sure fire solution.

Okay, you've "crossed your fingers" and "clicked your heels together three times" and said " That there is no buzz, there is no buzz, there is no buzz".  Now it's times to pull the switch out and put it on the work bench.

        Apply power and see if it still buzzes.  If it doesn't, then your problem is most likely somewhere on the track where it was installed.. 

        If it is buzzing, then you will have to uncover the bottom of the switch to reveal the wiring and the mechanism, looking for damaged parts. Shorts on the boards will be problematic, but you at least will have eliminated several possibilities. look especially at the geared swivel that contacts the micro switches at the end of each sides travel.  "Click" them manually to see if they work and if it would stop the  "BUZZ".  Lets us know what happens.   Dennis M.

Thanks Dennis - I figured I'd probably have to bite the bullet and remove it.  How do you apply power to it when it's not on the track? 

The quick and dirty way is to just jumper the lead in rails of the switch your existing track and apply power to your track.

I had the same issue . I found out the problem was with the remote switch not the turnout   itself. Before I could check the wiring it stoped working.  Since the turnout is at an easy to reach location I just operate it manually .

My first step would be to check the micro-switches that limit the switch travel.  They're the most likely candidate.
