I always find the solution to problems by reading what others post, and never need to post my own. That is not the case this time.
My 2005 (Balboa Parts) Four Winds spa quit working. Trying to restart it, I ruined a relay. Long story short, I replaced the bad heater, soldered two relays for sensors, replaced sensors, and soldered a broken wire on the transformer that I'm pretty sure I broke.
Fired hot tub up and it ran perfect, minus one jet adjusting knob snapped off. Ok so it ran for two days at temp without issue. Got in one night changed temp everything works great.
Go to get in last night and it is at 70 degrees and even though the heater light is on it wont get hotter than 70. A few things to note, it worked fine for a few days, it is 20 degrees outside temp today, and the heat sensors do not appear to be adjustable (as far as I can tell) as they are just the plug in probe type. they are new also.
I have had the tub in FC mode I've had it in f2 and f4 and f6 just to see. Also I made sure its in ST so im at a loss why it stopped getting hot.
Ive had it at 102 before when it was really cold, so I would not think that was the issue. Any thoughts?
Thanks in advance
