There is NO guaranty on defrosting using a Knife or Icepick !!

I regularly used to tell my junior Technicians, "Don't bother trying to
speed up defrosting the Lab Freezers with a knife or icepick". Just put
it on a dolly and put it out on the loading dock for the dump , and save
everybody a lot of time and trouble.
The proper way to Defrost a freezer is Just unplug the freezer and place
a large pan of hot water in the freezer and close the door, replace the
pan with more hot water until all the ice melts. All you need to do is
scratch the Evaporator to destroy it !! This is NOT covered under warranty.

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.

Cost, cost, cost, cost.

What's wrong with a couple pans of hot water, rags at bottom, close the door,
wait an hour while you do something else! People who have to have instant
gratification for a task that's performed once a year if that!
