Fuse fan - going although nothing is on

SueBC

Newbie question - should I be concerned at all that the fan in the little black fuse box is on, although I have nothing on in the T@B? It is a hot/humid day today. My assumption would be temperature would trigger the fan?  Or maybe I've just noticed it for the first time. I have the trailer on shore power (at my house) and also the battery knob turned to green (on) to charge the battery. I have the stereo going - that's all. Sorry for the somewhat basic question. Thinking its doing what its suppose to do.

Even though you have nothing turned on, your converter is probably charging your battery. I notice mine often comes on for a while when I first plug in the camper. I'm not exactly sure what triggers it--anecdotally speaking, it doesn't seem to run all that often.

When plugged into shorepower, the converter runs to charge the battery and you will hear the converter fan during that period.

Thanks - that makes sense now.
