So, I haven't gotten around to closing my pool yet. We've had this blast of cold air come through like most of the country. I noticed last night that although the air temperature was 32, the pump was not on. It is set to kick on at 35. It has worked flawlessly for the last several years. I've had no timer or pump problems this year. What could be causing this? I checked the sensor and nothing is covering it. My plan is to get it ready to be closed this weekend so it's not something that will matter before long but am curious if there's anything I should be doing or checking for.
