I don't see how.

You said: "there was a small air compressor plugged into the 2nd
outlet of the duplex outlet that serves the fridge that I was using to
blow out the coils."

I don't see how anyone could have been using an air compressor to blow
out the coils if no one was home. g

Quite simple, really. The air compressor's got a slow leak in the
quick-change hose valve (a cheapy Harbor Freight deal). When the unit loses
power for more than a few minutes, it's unable to top itself off and the
tank loses pressure.

When electricity is restored, the unit automatically comes on to bring the
tank pressure back up. It only takes the power being down long enough for
the tank's pressure sensor switch to trigger to cause the fridge and the
compressor motor to fire simultaneously. That all occurs without anyone
being present. When the tank reaches pressure, the compressor motor shuts
off. So it could be the dual starting or it could be the abrupt shutoff and
reverse EMF spike of the compressor while the GFCI is also under load from
the fridge to trip the GFCI.
