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 spar...

It sounds like your furnace control board is sensing a DC voltage from your converter (charger) that it considers too high. In other words, it won't start until it no longer senses charging voltage, but waits for the lower battery voltage.

Have you tried starting the furnace, then turning on the generator? Will this cause the furnace to shut down?
