OK about an hour ago, I decided to try Propane mode. I checked outside and sure enough, the burner fired right up. After one hour, I checked the pipe stack and the coils on the back. Both are warm. With the unit on electricity using the heating element, only the stack got warm, and never the coils on the back.
It's been close to 1.5 hours, and in the freezer, what little water drops have frozen.
I guess the real test ill be in the morning after it's run all night tonight. But, for the sake of argument, if this unit runs on propane, but will not work on electricity only (i.e. Auto) and reminding everyone I just put in a brand new element, what could it be?
Control board?
