Transfer Switch Issues

Have issues with transfer switch in our 2008 American Coach Tradition 42F.
Do we have to replace entire unit and use the old one as a door stop or can we replace parts (Safe Guard)

If you know the manufacturer of your ATS you could call them to see if replacement parts are available and if not I would replace the entire unit

Good luck and let us know how you make out....

I would just replace the whole unit. The other question is, do yo have a Surge Protector installed or may use a portable one?
If you don't then while you replacing the ATS I would install a Surge Protector also.
No I must also ask, what sort of problems are you having with the ATS?
Also did yo perform and inspection of the Shore Power Cable, in other words at the plug end are there any burnt marks between or near the prongs, if so it may need to be replaced also. Also check the cable ends in the ATS, if any of the ends have melted rubber on them they should be replaced also. These are all signs of over current which is usually due to a loose connection.
Just remember money spent now can save you a lot of money in the long run.

Its highly recommended to also add a full EMS unit. One that fully qualifies the power before gating power through to the coach - high/low voltage and frequency, pedistal wiring correct, etc. Plus provides a delay to preclude damage from rapid on/off power cycling.

Progressive Industries is a very popular brand with a lifetime warranty and excellent technical support. Available in hard-wire or portable versions - both with the same functionality.

Hi ! Welcome to IRV2! We're sure glad you joined the gang!

I would replace the unit. As someone else suggested, if you don't have a Progressive Industries EMS unit then I would highly recommend you get one.

Good luck, happy trails, and God bless!

For beginners, I have no idea what ....issues.... mean, but assuming that it is the transfer switch, I'd first pull the cover off for a looksee.
If it's never been touched, most likely you will find loose connections at the relay contactors, that are easily tightened. However, this looseness over time, has probably caused heat buildup, resulting in some of the wiring becoming crystallized. So replace or cut off the stiff portion, if it will still reach and you should be good to go.
I did this in a campground once and haven't touched it since, although the original problem was the twist-loc connector not making at the coach and resulting in a loss of the neutral return to the pedestal.
With what I saw in mine, I definitely wouldn't replace the whole thing, when not all that much trouble to just replace a bad relay, that should be available from any industrial parts warehouse.
Again, you haven't given much info or with attesting to trying anything, thus far.
