Control thermistor, AKA "Reg Therm" used on many Hot Springs, Limelight and Tiger River Spas from 2002 - Present. The thermistor screws directly into the heater and connects directly to the circuit board. Watkins Mfg. recommends that this control thermistor is changed with the Hi-Limit thermistor, Product Code: 39525. This thermistor will work with the No Fault 6000, No Fault 4000, No Fault 5500, PDR and tri-bend heater. New updated version extends housing, allowing sensor to sit deeper in heater which improves temperature readings.

Please Note: This thermistor does not include the o-ring. If needed please see Product Code: 34878
