IOTA Transfer switch seems to be sticking

You have the 2004 DSDP? If so, I would replace the 50 amp transfer box. You could take it apart and file the relay points. Odds are the relay points are pitted from years of engaging with a load. Your symptoms point to that. You can also find just the relay's and remove the old and rivet the new ones in, but I would just replace the Complete Transfer Box. After 13 years, that is not a big cost to do. Doug

Here is a LINK to a post I made last week about the IOTA ATS. Mine was doing the same, as far as the contactor(relay) chattering and sticking. The IOTA is a time bomb just waiting to go off.

I have a DSDP Newmar. I have noticed when I start my generator, the transfer switch clicks after starting but it doesn't click right over for a contact. I lightly tapped the top of the box and it clicks further to make a contact. I shut down the generator and started it again to activate the transfer switch again and it clicks right over.

What does one do to fix this situation? Can you clean or lubricate the swivel points inside? It doesn't take much to have the contacts come together with a light tap on top of the box. As I said, I've repeated this process over and over and it clicks right over after the initial tap.

Any suggestions for me?

What year?

Just FYI, but NTSB recalled The transfer switch described below for Monaco coaches 2008 thru 2011. To my understanding it was industry wide.

NHTSA CAMPAIGN ID Number: 12V060000 NHTSA Action Number: N/A

Component: ELECTRICAL SYSTEM Potential Number of Units Affected: 249

Summary:
NAVISTAR IS RECALLING CERTAIN MODEL YEAR 2008-2010 BEAVER AND CERTAIN MODEL YEAR 2009-2011 MONACO, AND CERTAIN MODEL YEAR 2009-2011 HOLIDAY RAMBLER RECREATIONAL VEHICLES, MANUFACTURED FROM OCTOBER 25, 2007, THROUGH AUGUST 26, 2010, EQUIPPED WITH IOTA ITS-50R 50 AMP AUTOMATIC TRANSFER SWITCHES.

THE IOTA ITS-50R 50 AMP AUTOMATIC TRANSFER SWITCH BUS BAR AND/OR ELECTRICAL CONNECTIONS MAY BE INADEQUATE TO HANDLE THE ELECTRICAL LOAD.

Consequence:
ELECTRICAL OVERLOAD OF THE TRANSFER SWITCH COULD LEAD TO OVERHEATING, AND A FIRE, INCREASING THE RISK OF PROPERTY DAMAGE, PERSONAL INJURY, OR DEATH.

Not sure what you mean by "click right over" but there is a built in delay. Try starting the generator and see what happens without doing the tapping routine.
