THALL Posted April 24 Report Share Posted April 24 Pentair/Sta-rite 400. I had heating problems with the spa, replaced the thermistor and high heat sensor, and just for fun the thermostat (now it leaks of course), but just when I thought I had some success and shut the whole thing off, the heater and blower came back on--even though jets were properly off. Went ahead and ordered a new pad because the LED readout was nearly useless and buttons seem inoperative as well for setting temps. I threw the breakers and turned off the gas. Thoughts? TIA! P.S. The system is apparently so old that I can't the right sized pleated filters for the filter housing, so I'm doubly PO'ed. Quote Link to comment Share on other sites More sharing options...
