HELP Converter making noise

[Dray]

I'm going out tomorrow so last night I plugged in the PU to an outlet and turned on my fridge using the 110 switch.  Came home from work today and heard the thing humming kind of like a fridge does in your house.  I hadn't heard that before but thought it might be normal.  I went inside the PU to check the fridge and found that the noise was coming from the converter.  Is this normal?  Is there a cooling fan on the converter?

Yep......Normal

There is a cooling fan in most converters.

There is a cooling fan in most converters.

Thanks Wavery.  I was getting worried.  Will it just shut off when it gets cool enough?  It's been running for some time now.  I have the PU in my garage and it's a hot one today in Sacramento.  Thanks again for your help.

I don't know about all of them but the fan in mine runs the entire time that it's plugged into 110.

Mine runs at three speeds (inaudible, low, and not too offensive).  Come August and 90
