Is there a fan in the fuse box?

Hi guys. I just got my 2011 Jayco Jayflight out of the storage lot. Got it home and plugged it in. Now, there is, what sounds like, a fan running inside the fuse box. The fuse box right beneath the stove. It is about 106 degrees here now, and it has been sitting in the sun for a long time. Is there a fan? and is it going to run until the fuse box cools down? I can't find a off switch for it. I noticed it after I turned the environmental panel to "fan" to test it, then I turned it off. That's when I heard the "fan" running in the fuse box. Does anyone know what this is and should I worry?

Yes you do have a fan in the converter box. It has a internal thermostat and will keep things nice and cool. So kick back and enjoy a cool one. You have nothing to worry about.

I have a WFCO Converter. The fan cycles on every power-up. It would also run when the 12V amp draw was high (i.e. = after turning on most of the inside lights. Rigging up your exterior running lights to be on when disconnected from the Travel Vehicle also puts a high amp draw on the converter when plugged up.

Since installing LEDs....over a year ago....my converter fan has not come on.
