I have a related question as a fairly new guy here. Is it just as critical to be level when I am plugged in and running on the 120 V refrigerator? I understand why when running on the flame it is important. But to me it seems like running on electricity it won't be quite as critical especially if only slightly off level
Running on electricity is the same process as running on gas—you're just using an electric heating element instead of the gas flame. It may be very, very slightly less important because the electric element is typically less powerful than the flame, but running too far out of kilter on electric will cause damage in time just as doing so on gas will.
