New spa problems

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!

They click shut but since the points are burned, the current has a hard time passing thru.

I didnt, I just shut off the current, took one (front) side off the control box wherein the thermostat is found, wound the thermostat switch to its lowest setting (opens the point gap more) and put the sandpaper or a "points file" in there and smoothed them down. I also found a small hole in the thermostat housing that allows an 'allen key" to be inserted..when it is turned, you can see it changing the gap- it allowed me to put the desired setting into the dial..I put the dial about halfway, then turned the allenkey til the points clicked.

Rudy, thanks, I am away from home, but I will do exactly as you suggest when I come back. thanks.
