Checked the breakers...good. Checked the one and only GFI outlet and found it popped. Reset same and everything is now good to go, including the fridge.
I did not know the fridge is protected by the GFI outlet, and I figured some of you may not know it either.
Ground Fault Current Interupters are normally required where people occupy the space and the risk is higher than normal for someone to be shocked by a electrical circuit due fault to excess grounding potential, normally water. These circuits are used in bathrooms, ie tubs and showers, kitchens, near the sink and outdoor outlets. Many folks blame these GFCI outlets for trouble in more areas than they really exist. A common refrig in a home is not GFCI protected nor would it be in a RV. Having said all that, the designer may have figured all the other nearby outlets must be protected therefore add the frig instead of running separate line just for one outlet.
