Power Converter Fan Running - Normal Operation?

[ob1]

I plugged (extension cord 110 supply in garage) my '04 Utah in for the first time this season.  Switched the Refrigerator to AC.  I have lights working and everything is fine.  The only thing I have turned on is the fridge.  My question is - should the fan on the Power Converter be running?  It's been running continuously for approximately 4 hours after I plugged in.  The battery was charged last night for 10-12 hours at the 2 amp trickle.  it's hooked up correctly + & -.  

Thanks

I believe that's the cooling fan for the converter and it's normal.  Mine does the same thing.  Whether your actually using much 12vdc or not, the converter is still converting and charging your battery and supplying 12vdc to whatever circuits use it.

Sounds like the converter fan is running to cool the converter since the battery is being charged by the converter and the lights are on.
Depending on the battery's state of charge, 10-12 hours of trickle may not have it charged fully.
Without a volt meter of hydrometer you'll never know what the battery's state of charge is.

If you are running your fridge on 12V the fan will continue to run.
