I took the old switch to the new Campers Inn in Woodstock Ga. They had a tech that had one, unused, from another issue, which they gave me.
He also showed me there was a tiny button on the switch that was a reset. After resetting, it OHMed out and I put it back. Now I have a spare.
Apparently when the cooling unit failed, this tripped.
Life is good. Thanks for the help.
