Progressive Dynamics ATS failure
Count us among the latest to experience the PD Automatic Transfer Switch (ATS) failure. We do not have a generator. Luckily it was the last night before returning home from FL. We plugged in to the site power pedestal and our Southwire SurgeGard gave us 2 greens and read all was well with the power. Went inside our 2021 3121 and no 110 service. The remote LED in our cabinet panel showed shore power. After having previously read about the possibility of problems with the PD combo ATS / Surge Protector I pulled a lot of stuff out of my storage compartment and removed the passenger side rear access panel (behind the steps) to access the ATS. Sure enough, upon meter testing, I had 120v on both legs in from the shore cable but nothing out AND I could not get the relay to engage. SO, one night with no a/c and not opening the refrigerator door.
I spoke with PD today and they are sending a replacement ATS but not the one originally installed, at no charge.
