Refrigerator must be on its own circuit AND must not be
GFCIed. Obviously if the GFCI tripped, and was reset later,
then the refrigerator has lots of unrefrigerated food that a
human might not know about.

Same applies to a circuit used by both refrigerator and
other appliances. Another appliance tripping the circuit
could leave a refrigerator getting warm. Again, a human
safety issue solved by putting the refrigerator on its own and
not GFCIed circuit.

thinking about this further.
Does current code call for 2 GFCI protected outlet circuits and an
additional one for a refrigerator?
If that's the case I need to have a new 20A circuit run for the fridge.
