Fuse box fan

[Jose&Kristen]

We have noticed that the fan located in the fuse box comes on whenever we turn our stove light or the light over the kitchen sink. Both of these lights are on the same side of the trailer as the fuse box, which is under the refrigerator.

Does anyone have an explanation... or at least an amusing theory... as to why?

The fan comes on automatically when the converter detect a higher current usage to move heated air from the unit.

So why does the fan come on only when one of those two lights is turned on, and not with other lights? Or when we use the outlets?

Those are probably higher wattage 12v bulbs. The outlets are 120 and are not connected to the converter.
