I was looking at the owner's manual of a Magic Chef refrigerator and it instructs the user to avoid putting it "in a moving vehicle. This unit is not designed to be installed in an RV or used with an inverter. This unit is intended for household use only."
The product specifies 115/120 V, 60 Hz house current as the required power source.
This brings up a question re: inverters in general. The manufacturer of an appliance cannot reasonably anticipate all permutations of RV power systems out there, hence restrictions that will void the warranty if the user defies them. In terms of physics, what matters is that the juice going into the appliance is the right voltage, frequency and amps. That's what you get with the inverters sold by the company mentioned in this post on available inverters/chargers
. So am I correct that one wouldn't have anything to worry about with a proper inverter? Every appliance/electronic device I recall acquiring has outlived its warranty.
As far as a household refrigerator being too delicate mechanically to survive use in a motor vehicle, I suspect that's a non-issue unless you're doing serious off-roading. They have to be built tough enough to survive the trip from the factory (usually in China these days
) on ships, trains and trucks to your friendly neighborhood Walmart/Home Depot/Sears etc.
