Transfer switch burned - Again

[edatlanta]

I had a failure of the original IOTA 50 amp transfer switch in March 2012. Jayco replaced it with a Progressive Dynamics PD52 since IOTA was no longer making transfer switches. Well this morning the PD52 burned. This was the hottest day of the summer wouldn't you know. I just wired around it to get power back, of course I can't use my generator, but at least I have a/c.

One 120v leg burned completely in two so I had one a/c still working, but it was the small unit in the bedroom. It didn't take long to figure out what had happened since I had been down this road before.

Thank goodness I still have one more year of extended warranty.

Transfer switch problems seem to be common.. Read a lot about them in the forums.. My buddies big Tiffin MH switch went out last Jan in SoCal.

They arre usually caused by loose connections. I have learned to check them as soon as I get a new unit. Same goes for the breakers.

I checked the connections just under one year ago. The switch was installed in March 2012.

I talked with my dealer this morning and they are getting the extended warranty approved and the replacement switch ordered. When I get back to my home base in 3 week they will install it.
