Well this is baffling. So when hooked to shore power or Genny power it works fine?
Hopefully someone else can enlighten us.
I guess check for loose connections around the heater/Fan? Not sure if that would do any good if it works on AC/Genny power but perhaps you will see something questionable??
Check Battery volts just in case??
