Got a 2006 Mallorca and it keeps tripping the hi limit circuit. I have ohmed out the thermistor and confirmed its good from a temp/resistance chart. Wierd thing is, is that it is tripping when the tub is not at set point (tub @100 and thermistor is supposed to trip at 118), when the thermistor is cold (even put it in ice water for testing) and sometimes at startup. I can reset power about 3 times and it will come back. I have good water flow, clean filter so im thinking the Spa controller has gone bad. Any suggestions would be greatly appreciated
thanks
