After some further research about calibration I came across the following on other web sites. It seems the TRC Surge gaurd had issues in the mentioned years. There were a few different post of people experiencing what I have. My coach was made in 2013, although not a Newell, but same transfer switch.
Hopefully Fleetwood will install a new one. There is a calibration method too. So why don't they calibrate them before sending them out of the factory?
It turns out that the Tech guy at Newell called me today to get me to explain my problem, and what the cure I found was. When I explained it to him, he told me that it may be the answer to a problem they have been bombarded with from 2013, and 2014 coaches. The owners would plug into 50 amp Shoreline power, and the transfer switch would not kick in to supply power to coach. The new Surge Guards are from the same manufacturer, and will do the same thing, even worse because the new ones will monitor, and store the spikes, and if it gets to 130 volts, it won't kick in. I hope this solves their problems too.
