We had this happen in our 2010 Serrano 31Z. We had the coach plugged up to our house connector (we had installed), but I didn't have the surge protector plugged in
. I came out, and found the microwave was toast, and the receptacles wired through the inverter would only work with the inverter turned on now. Before, the internal switch in the inverter transferred the power from external source.
Turns out a surge had hit our coach strong enough to mess up a few things. The inverter worked in general, but the internal transfer switch no longer worked. We had to replace the inverter (got a new one from best converter), and the microwave. BIG, expensive lesson learned. ALWAYS use the surge protector, and unplug anything not in use.
