First off-
Thanks to those of you who share knowledge on this forum, it has been a huge help getting off the ground with our first spa.
Now for the problem...
We bought a used spa, an older L.A. Spas "Nice" model. The switching is pneumatic. Today, I had my electrician out and we wired everything up. The good news is, the jets, blower, and light all seems to be functioning properly, as are the switches that control them. The bad, is that there is an awful noise that I hear coming from the controller both when I turn off the blower, and when I turn down the themostat. Some poking around has me thinking that it is the contactors "chattering", making a noise kinda like a clothes dryer buzzing at the end of cycle.
My first thought is to replace the contactors. Does that seem like the thing to do?
Beyond that, I am concerned that the high limit switch might be wonky (I don't feel any resistance when I push or pull on it), and the timer looks pretty faded, but may work fine. I haven't wanted to leave the system on long enough to know if I'm getting heat, we live in an urban area and I don't want to bum our *very* nearby neighbors out with the contactor noise.
I'm pretty confident I can replace any bad parts pretty easily. I have rebuilt mixing boards, tube amplifiers and can do some car repair, so what I'm seeing in the tub's guts isn't terribly frightening. Still, I wonder if it would make sense to replace the guts wholesale, and not be stuck with another ongoing project. Any thoughts?
Any help is greatly appreciated.
Thanks!
