My pool temperature reading has been accurate since we've had the pool for the past two years. Last night I turned the heater on and it showed 76 degrees which seemed low but I thought might be correct and I let the heater run over night. This morning it was still reading 76 degrees both on the heater itself and the control panel. I put my hand in the water (don't have a in pool temperature gauge yet) and it felt much warmer than 76 degrees to me after having the heater run overnight. I also felt the water from the return jets and it was warm so I'm certain the heater had been running.
Is there a common component related to the temperature reading that can fail? Maybe the sensor?
