Application
If the temperature on your control panel’s display is showing an incorrect temperature, your thermistor may need to be replaced.
Thermistors often display a temperature that is much too high when they reach the end of their lifespan.
Fix this issue easily by replacing your worn-out thermistor temperature sensor with this 42001-0053S Thermistor replacement.
Make sure the power is shut off before replacement. Wear work gloves to protect your hands.
Pool Heater Isn’t Heating---Sometimes, your pool heater ignites but doesn’t reach the desired temperature. Or, maybe your heater isn’t generating heat at all. Both situations are very common.--Inspect your temperature sensor
