Here's the weird part. Three years ago I had the same problem -- when
I moved into this house, the spa was not working. So I went to a local
dealer and bought a new thermostat and installed it. It lasted about
that long, and now it i s bad again. WTF? Any idea just what might be
possibly wrong, or are these thermostat switches really that bad?

Yes. That type usually has "points" like an older car distributor.
Shut the power off and slide some very fine (400/600) sandpaper between the
points and pull it back & forth.
Make sure you get BOTH sides.



A-ha!

I think that that's it!

An additional tidbit is that as I rotate the knob of the thermostat, I
do hear a "click". At approximately the point that I would expect. So
the thermostat "clicks", but somehow does not close the contacts.

So, your suggestion is right on the mark, but I want to hear a little
clarification. Do I need to take the t hermostat body apart?

thank you!
