Woke up to the power out on the fridge this morning, an issue we have had several times when in parks with high voltage power issues. The GFI on the circuit the Refrigerator is on was tripped. The fridge is a 13 year old Whirlpool, but hasn't given this kind of issue unless we experience overvoltage conditions. I cannot recreate the fault by simply flipping the breaker off and on. Interestingly, this only happens at night when we are asleep. The icemaker is turned off, has been for years since we invariably get an ice sheet with a few cubes for the effort. The park we are in has known issues with high voltage. Our 50 Amp Progressive surge protector cuts power at more than 132 volts. The Previous Error message on the surge indicates PE5, an overvoltage condition on Line 2 and indeed I read 130 volts on Line 2 this morning. My question is, why would the GFI trip when the power is terminated? Should I be checking grounds on the fridge circuit?
