Thanks for the clarification. Warning, next part is long, so, proceed if you have the time
Well, it seems like some things have taken a turn for the worse, I left the spa running for 3-4 hours to heat up, and when I went to check on it, the relay was making a racket again. So I tried pressing some of the controls, and when I turned on the jets, the pump started sputtering, and randomly freaking out (hard to describe, kind of like on off on off in quick random intervals) while the flow and heat light flickered in time to the stuttering. So, this is sort of what happened when I let the heat stay on for a while (without the pump stuttering, thats new this time), and it leads me to believe the electronics that are supposed to stop the heater and pump when the heat is at the right temp are fouled. The Air switch worked fine and caused no issues. The light switch turn off the pump completely, hallelujah I thougt, it's righted itself. But now, the pump then started making a very weak attempt at turning on, similar to the stuttering but it seemed like it was the low speed mode this time. Turning the light off brought back the "normal" operation of the pump staying on in low speed, and the pump making a lot of noise and sputtering when it was at full speed.
At this point, I tried to lower the thermostat, and see if that would change the mode the electronics were in, and it did after a bit. Once the temp dropped below 104, I tried the jets, and they worked again. It seems like not being in "Its hot, turn off the pump and heat" mode stops the pump from whatever problem the electronics are causing.
So I'm going to live with this nonsense for the short term, but now I'm unsure if the pump is messed up or not. Is there an easy way to test the pump? Like hooking a direct switch to the wires or something to just make sure the pump itself is ok, and the problem is isolated to the electronics. Also, one other question, how much would I reasonably expect to pay for the install of a new pack, plus the plumbing work?
Thanks for reading, your help is appreciated (all of you).
