My Aqualcal model TT120 pool heater runs, but will not heat.Panel shows 112 degrees water temp no matter what desired temp I set. I measured the resistance of the temp probe at 5 kohms. whrn I disconnect the probe leads, the display shows "PO".When I jumper the to inputs to the board the display shows "Pc".
I removed the thermostat and put it in hot then cool water and measured the resistance.
77 f = 12 kohms
108 f = 6 kohms
What do you think ?

SIMPLE TO REPLACE AND FAST DELIVERY. DIDNT KNOW THE OLD ONE WAS BAD UNTIL IT STARTED LEAKING. NOW I KNOW TO CHECK THIS OCCASIONALLY TO PREVENT MORE COSTLY SENSOR REPLACEMENT OR MORE
