I lost this forum! Somehow the emails were being sent to my spam! I got that fixed and found you guys again! Thank you so much! Ya'll really seem to know what you're talking about! I get the code about 45 seconds after I turn on my hot tub, which I do by just fliping the breaker on. I took another reading (water hasn't been heated, not sure on water temp but ambient temp is 54F). On my multi-meter the probe before the heater is reading 47.90 the probe after is reading 56.36. Last time they we're both at 42 and just off by .44 My meter doesn't have different resistance settings, after the numbers it does say k, then the ohms. But maybe now this shows that maybe one of them is actually bad. Visually they look perfectly fine, but I don't really know what to look for. Mainly, You guys are awesome and thank you so very much for the help! This place is great!

Howdy! I've been getting a "Sn" error code on my clearwater spa and I've spent the last few hours trouble shooting it and I'm not compltely sure what the problem is. I've tested the resistance between the two temp sensors (if I understand correctly, one is high limit sensor and one is a temp sensor) and they both come in at a similar ohms rating. So I don't think they're damaged, but yet I'm still getting the error. Should I replace them anyway? Or is there a different part that is the culprit? I'm lost, please help! Cheers, Carl
