Hello I have a Blue Ridge Spas Bought it used but it never got the water hot hot but warm enough where it wasnt cool . So this year i wanted to fill it up and when i did the Temp sense went out it wouldnt let the heater kick on . So i bought a new one and now the heater is on and when i put the dry sense in the hole where it goes it shows the water like 95 and the heater kicks off . But the water is luke warm .

Describe how you replaced the temp sensor? Did you trace the wires back to some connection block or did you snip the old wires and splice the new sensor in? On some sensirs the wires are part of the measured circuit and you cant splice the wires without affecting the measured temp.
