Follow up: I tried some new batteries that were rated at 4000 mAH from Batteries Plus here in town but only lasted couple of days then same problem. I now have order the AC fan and should be here Monday or Tues and will install that when it warms up. Fan works now during the daytime hours so will have to do. Expecting temps of -30 with wind chills to -60 to -65 on Tues, Wed. I don’t like snapping off covers and unhooking wires to bring the unit inside when it’s that cold or standing out there. Just looking for more trouble then. Thanks again for the help CW2274 & Valentine Weather.
