My LXiheater works but the internal water temp indication on the control panel starts at 70 then rapidly runs up to 104 which is the max set temp limit and shuts off the burners. To get them back on I can shut off circuit breakers, then reset and the indicated temp resets to 80 and the burners come back on. After an hour or so the temp indication builds back up to 104 and shuts off the burners again. I can repeat this cycle to get my pool up to swimming temp...It acts like a bad temp sensor to me ...any suggestions?
