What would be nice is a valve to short circuit the metering device and let
the hot vapor from the compressor flow straight into the evaporator coils.
That would defrost it in a matter of minutes. I've heard of a few very old
refrigerators that worked this way but nothing modern does it.

One more thing to go wrong with a sealed unit.
