- No miracle, just moderate-tech.

- The frost still forms at the 'normal' rate, but once a day, the freezer shuts
- down, electric heating strips (located at strategic positions throughout the
- freezer perimeter and cooling coils) are turned on for a predetermined time.
- The frost melts to water which drains out the bottom of the whole mess.
-
- The timer for this process then returns the compressor cotrols to 'normal'.
-
- The older units had a pan underneath the fridge which had to be emptied of
- this condensed water from time to time. More modern ones have this pan
- strategically located underneath to enjoy the flow of warm condenser air (fan
- driven) to evaporate it back into your pad. This pan sometimes gets cruddy and
- should be washed clean. If you poke around enough under your fridge, or better
- yet read the manual (!!!), you will be enlightened accordingly.
