I have a 2002 Sovereign that is driving me NUTS. I replace the heater control board last year after it burst into flames. The tub worked flawlessly all winter (and a COLD winter at that.).
This summer I read about summer mode and activated it, tub didn't get used all that much. I did notice the temp was low one day and de-activated summer mode. No heat and found the heater reset tripped. Reset and everything was fine for a few days. Then no heat again, reset was tripped. Pulled and cleaned filters. Tested heater resistance (10 ohms). Checked connections and restarted. Made it 1 week, them BAM, no heat. Heater reset again.
I have determined it doesnt matter if the tub is used a lot or not. Damn reset keeps tripping.
Am I needing just to bite the bullet and replace the heater?
Thanks in advance.
