  1. Thanks for the info, guys. Hmmm.... I wonder if there is any way to find out if the tub is meant to work with a 50 amp gfci, or if it needs a 60 amp GFCI because it actually draws 50 amps when running. I hate to start blowing breakers, or worse yet, be running right at the edge of safety without knowing it. Unfortunately, I have no other documentation with this tub (older L.A. Spas "Nice" model" beyond what is on the controller panel. Internet searches have proved fruitless... Having heating with the jets on high sounds like a nice thing to have!
  2. Hey Folks- I got my contactor issue sorted out and my new (used) tub is now heating. I was looking at the block diagram on the electrical cover, and it shows that my tub is convertible to 120 @20A, and 240 @ 30, 40 or 50 amps. The previous owner told me he had the tub on a 40 amp circuit, and looking at the conversion block, it does appear that he has the controller set up for that. I have a 50 amp circuit run to the tub, so I would like to take advantage of any extra power that I presume I could get with the extra 10 amps. I believe I have identified the wires shown as "x" and "y" and understand that they should be moved over to slots 3 and 4 on the converter block. I am wondering if the wires above need to be moved as well. I'm hoping one of you spa wizards might have seen such a thing before. Any advice would be greatly appreciated! Cheers, Ryan
  3. Hey Gents- Thanks for the replies. I did try to clean the points, but the noise is unchanged. I will probably just get them replaced, though I still can't decide for sure if I am best off sinking money into parts on an obviously worn controller, or if I should replace the unit wholesale. In the meanwhile, I'm spending waaayyy to much time researching the archives. Cheers, Ryan ps. Rob- Thanks for the heads up on the high limit. I wondered if it was supposed to be that way, but wasn't sure.
  4. 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! Ryan
