New spa problems
I have an old spa.
At some point recently it stopped heating water. It still circulates, though. I have traced the problem to a faulty thermostat switch (with a knob to set desired temperature). The proof of this is that if I electrically connect two terminals of the switch, then the heater relay closes. That is not happening if the thermostat is set even to its highest setting. 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? thanks i |

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. |

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! i |

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? 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. |
