Furnace works on batt power but not shore power...?
I discovered an interesting problem with my furnace: Most of my camping over the past couple of years is boondocking and the furnace runs fine. It will dependably fire up generally on the second spark of the ignition... on battery power!
Over the weekend I was boondocking and required heat at night. The furnace would not fire up while running the Honda 3000eu. I tried several times (furnace shuts down after 3 spark/ fire attempts) many manual cycles after the furnace does its own 3x to start.
I do not run the genny through the night. It is used primarily to recharge the batteries and run the MW when required (and rarely the AC.) This particular time, the genny happened to be on when I wanted to fire the furnace to warm up the camper before retiring. Usually the genny is not running when turning the furnace on.
For grins, I shut off the generator and low and behold the furnace fired up! For more grins, I shut down the furnace, turned on the genny again and tried to fire to furnace to which it DID NOT fire up on the generator power.
A couple of years ago I recall an issue where it wouild not start no matter how many spark attempts very similarly to described above and it was when plugged in to shore power.
Any ideas or comments on this oddity? I am puzzled.
