I think the IQ-2000 on my 1998 Jetsetter has went crazy, the problem started last week possibly after a lightning zap. (we had a number of thunderstorms before I noticed the problems).
Here go the symptoms in no particular order
Light stays on in tub, pressing up or down button has no effect on brightness, but will turn off light icon on the screen
Tub is too hot (probably around 106-108 degrees and ignores changes to the temperature set point. (I lowered the set point to 94 degrees waited a few hours and it was still hot)
So is there any hope of fixing it or should I break down and swap it out for an IQ-2020, control panel and LED light?
