I am not sure anyone described the sail switch for the OP. The sail switch has to be blown closed by the fan before power is allowed to reach the rest of the furnace. If the sail switch sticks open, even a little bit, the furnace will not operate. A sticky one could fail to make contact with a small drop in fan speed because of slightly lower voltage. I hope this is helpful.
Ok thanks, that was the critical info I was missing that didnt really allow me to close the loop on this.
I am going to have my battery tested. But last time I tested it myself it was good. (once charged and left un connected it stayed at 99% for 24 hours.)
I am on my way to Alaska and I really want my furnace working correctly. It will still be plenty cool there at night in early June and on the way up.
