UPDATE: Sorry--been offline for some time. Major RV trip taken. Transfer switch hums "quietly". I can't hear it at all inside the rig now. Only if I open the door and listen. So I'm happy with it--I guess

I'll say it again they do hum.

My new A class has a manual plug in and out no noise with that.


Take a look at the Progressive Dynamics website and call up the
PD52DCS. Their big push is that this one does NOT hum. And they told me that when I called. The new one should be here tomorrow. Installed May 7. Update then.

Only possibility would be high or more likely low voltage. It is possible that a poor connection or missing ground to residential power.

4/17 second update. My pd52dcs transfer switch is noisy! They will send a new one. CW EMPLOYEE Thought it was my power source at home! Can that be true?

3/19 update: my batteries failed to keep a full charge with the old transfer switch. Of the four lights on the panel it always dropped to three quickly then two and finally one light. NOW with the new transfer switch itโ€™s not only quieter but the four status lights stay onโ€”day after day! Not sure why. In both cases the mh was unused. Perhaps the old transfer switch drew power out of the batteries just sitting?

I tightened connections. No change

Is there a better model available?

Tightening wire connections, only insures a good connection that won't get hot and cause crystallization of the wires and other current delivery problems.
Pull the relay contactors themselves and use emery cloth and a small file for cleaning the contacts and where the coils make contact, as well.
Had to believe they're all making noise or that they all are bad.
Check the little springs on the arms, while you're at it.
You can always replace one with a like model, if really faulty.
With re-reading the thread, it seems that the deed has been done, so you might as well ask for the old one back for having a looksee and for having a spare, if needed.

they all hum your new one is newer so hum is lower and because they put more sound board around it you older one did not. I guess spending the money make you more secure great happy camping.

I understand they are. The DC conversion is all internal. You might want to go to their website and submit a question. I've had to clean relays about every 3 years on our last 2 RVs. After a while you get good at it. It's dusty here out West.


Thanks Gary. I did call PD and he said the DCS will transfer over easily. Main difference is the size of the box.


UPDATE: MH is sitting at camping world now getting the transfer switch installed. I'll let you know how it works:)
