Would someone not think to consider...
this is high electrical storm season !!!
Power surge from lighting storms are a nightmare on electrical equipment.Having worked in the communications industry for over 40 tears and being trained on proper grounding and power surge of sensitive equipment .... It has been my observation that no one can be protected from "acts of God" note ! the weather. We are lucky to have fewer storms this year than some in the past. Sorry,it happens !!! yes ,I've replaced mine in the past,also
Just think of it as a cost of keeping your cool !

Thanks
