What is that thing under the sofa?
Okay, I am brand new to owning a trailer of any kind let alone a Jayco and own a Jay Flight 264BH. Here's my question...I had the trailer plugged in to a standard 110 household outlet and came into it tonight and heard something running, like a fan, but it was coming from under the J-steel sofa in the trailer. My problem is that I know they told me what was under there during the walkthrough but I can't, for the life of me, remember what I was told it was. The trailer has only been plugged in but no water added to it and no furnace turned on or anything. Does anyone know what is in the mystery box under that sofa? It has a grate on it and sounded like a fan running. There is nothing directly outside the area that might suggest what it is so now I'm counting on all of you veterans who might be able to shed some light on this mystery. Your guesses?

That would be the furnace under the sofa. Don't know why it would be running if you had the furnace off, though.
Have a good one,
Bill

If there is nothing directly outside of it, it won't be you furnace. It is more likely your power inverter. They have a cooling fan in them that will run when you plug the trailer in to shore power.

I'm going to guess that it's the cooling fan on the 12v converter. They're equipped with a small fan to prevent them from overheating. My 12v converter has a variable speed fan that runs continuously from the minute I plug the rig into shore power. As the load increases (like turning on some lights, furnace blower coming on, or anything that requires 12v power to operate), the increased demand for 12v power causes my converter's cooling fan to speed up so the converter doesn't overheat.

Prizes to both FPM III and hammer for guessing the power inverter. I spoke with the dealer today and they said that it was the fan on the inverter that was making the noise and that's completely normal...I was told that you don't hear it very often but it will come on from time to time. So that solves another "new trailer" mystery for me. And here I ran outside and unplugged the trailer because I was afraid that something was running when it wasn't supposed to be. Go figure!

Converter. Jayco's do not come with inverters. Converters convert 115 volts to 12 volts. Inverters do the opposite.

I missed that one, huh. Well, the boogey man under MY sofa IS the furnace! LOL. My power converter is under the refrigerator.

I know several of you said it was the Converter - but on a 26BH the converter is located under the fridge. The furnace is located under the sofa.
Is there air coming out of the floor vents? The furnace is fairly loud and very noticeable. I am not sure I have ever heard the fan on my converter since it is behind the cabinet. It is possible the sound is bouncing off of something and only sounds like it is coming from under there??
You should be able to remove the drawer from under the fridge and you will see the converter and possibly hear it.

If it is the furnace fan, make sure your thermostat control is actually turned off. The switch in our first trailer required qute a bit of thumb to turn it off. At first I didn't realize there was an off position, just the lowest setting. I learned that when the fan kept coming on if it was cool out even when I didn't want to run the furnace. Just a thought.

Okay, this may answer one of my questions from a post I just released...but I thought the converter was in the Power Center, which on my 2006 Jayflight 31 BHS is under the lower rear fold up bunk. Is there any way that I can be sure? I got the wiring schematics from Jayco on my trailer, and they have been very helpful tracing things, but they don't refer to where the actual converter is, just the power center. Thanks!

George - as far as I know, all the converters are right behind the power center but there could be some exceptions. If you want to find it, turn on every lightbulb while you are plugged into AC. After a minute, it should kick the fan on in the converter and you can use your ear to find it.

Correct. Up until the 2011 models, Jayco had IOTA Engineering manufacture there power DLS converter/2-stage chargers, and they were configured in two different ways. Many came with the ILC Load Center (breaker/fuse panel with black cover) and the converter/charger was mounted to the rear on the same frame. The other configuration was with the IOTA converter/2-stage charger mounted separate from the breaker/fuse panel, but usually close by.
I believe all the new Jayco models now use a Progressive Dynamics converter/3-stage charger.

Terry,
IMO the Progressive Dynamics is a better unit because it's a 3-stage charger. The prior Jayco IOTA converter/chargers that were mounted separate from the Load Center you can add a IQ Smart Charger to make them a 3-stage for about $20 (plugs right in). http://www.iotaengineering.com/iq.htm
The IOTA's that were mounted to the back of Load Center frame don't have the plug-in port.......go figure.
Bob

Yep - I have the one mounted right to the load center. I spent 20 minutes and a mirror looking for that port with no luck when I first got it.
So far it has worked well though. I leave it plugged in while in storage and it has not cooked the battery and I rarely have to add water.

Well under my sofa is a "blow up air matress"! It has its own electric air pump attached. I suppose if I left the switch on and turned on the poewr it would try to pump!
Just thought I would throw that in
