drjhnjhnsn Posted January 22 Report Share Posted January 22 I have an old Solana TX 2 person HT that has a problem with temperature display. If it read 82 degrees the tub will be 102 degrees. Not a big deal but I've had guests that have set the display to a 102 degrees but it gets much much hotter so there are some safety concerns. What would be the problem? (I guess I could just put tape over the display but would prefer a real fix) Quote Link to comment Share on other sites More sharing options...
ratchett Posted February 5 Report Share Posted February 5 I'm no professional but I wonder if it could be a failed temp sensor. If you have a multimeter you can test the resistance of the temperature sensors to see if they are reading accurately or not (which I bet they are not). Here is a chart for Watkins temperature sensors you can use to match up numbers Temp sensor failures are common, and easy/cheap enough to test and replace. I had a temp sensor fail on my 2019 Hotspring last year (which was covered under warranty) - in my case the tub went into protect mode allowing the circ pump to run, but not the heater.
