Designer 35RLTS and Jayco Talk...Thanks Frank!!

I had the transfer switch replaced at my Jayco Dealer. When plugged into shore power it hums pretty loud. You can hear it everywhere inside the coach, and outside too. Has anyone else had this problem?

This "Jayco Talk" thread also deserves continued Thanks to "Veteran Moderator" Frank (RIP) for originally allowing this thread to continue!

The thread name is a tribute! Thanks Frank!

We contacted JAYCO about the transfer switch recall and they told us any major service center can do the recall. Now if we can get some one to do it. We're getting allot of "we don't do recalls for JAYCO" guess ther's no money in it. It's a shame, it's getting close to "upgrade" time. Guess we'll travel 200 miles to the nearest JAYCO dealer.

Side note, Hope everyone has been well and Thank You to all of our veterans.

Be safe and start stockpiling.;)

The transfer switch is located in the same place on the Designer and the Pinncale.
It is behind the storage area panel that is next to the steps that go up to the bathroom / bedroom area.
If you remove the right side rear storage bay panel, you will see the transfer switch box mounted on a board.
Our Pinnacle has the new supplier / design transfer switch that is not on the recall. I removed the panel and checked it to be sure.
The transfer switch is only on units that are factory Generator Preped.
The transfer switch is basicly two large contactors that when there is a loss of utility power, the transfer switch transfers the coach power from the utility service power cord to the Generator power.

Below is a picture of my Pinnacle's transfer switch, notice to the left of the 1st picture is the backside of the steps going up to the bathroom / bedroom area.

The transfer switch's job is so the coach can only recieve power from one power source and the generator power can never be connected to the utility power source.
The block you see in the second picture between the two contactors is a interlock that allows only one contactor to be active at any given time.
Notice on the second picture the wires on top that connect the two contactors together, this is the coach power.
One set of the wires on the bottom go to the generator and the other side wires go to the shore power plug for the utility power cable.

LOL...I was feeling real stupid thinking I was the only one that didn't know where or how this transfer switch worked. They are closed now, I may try to give them a call tomorrow. Thanks though for the heads up.

Did some checking on a couple of other sites, it appears that you will only have a transfer switch if you have a gen or gen prep. On some of the Designers and Pinnicles it looks like the transfer switch is under the stairs accessable from the basement.

I also found this document which shows how to change the switch...models covered, probably more information than most of us need. My last edit on this subject...no genny, no genny prep, I'm not involved. Thanks guys:B

Just saw this posted via Facebook:

Jayco is recalling certain model year 2007 Greyhawk Class C motorhomes; model year 2008 and 2010 Seneca Class C motorhomes; model year 2009 and 2011 Eagle Fifth-wheel; 2010 Recon fifth-wheel; and model year 2008-2010 Designer fifth wheel vehicles manufactured from June 15, 2006, through August 13, 2010 for an improper electrical connection at the buss bar on the Iota-brand transfer switches installed in the vehicles. An improper electrical connection at the buss bar could lead to overheating and melting of the transfer switch, increasing the risk of a fire, injury or death. Jayco will notify owners, and dealers will replace the transfer switch, free of charge. The safety recall is expected to begin during August 2012. Owners may contact Jayco at 1-800-283-8267.

Where is this transfer switch located and what does it transfer. I guess what I am asking is does this have to do with a generator, or is it something to transfer between 110ac and 12vdc?

Congrats on the new rig. We are looking at new fivers ourselves, just can't find one that makes us want to get rid of the Jayco yet.
