Yeah, the usual complaint is that the freezer is too warm.
Freezer on top and Frig. on the bottom. Lots of frost on
the meat and stuff. Thermometer measures about -10 degrees
below 0. Reduced the freezer digital control from a 5 to a
3. Still too cold. Refrigerator temperature okay. Any ideas? Bought this thing a little over a year ago. Yeah, out of warrantee. Just my luck! Should have bought an Amana.

The problem isn't that the freezer is too cold, it's that too much moisture is entering either the freezer or fresh food compartment and condensing as frost on your food.  You don't want the freezer to be any warmer than +5F, if you're getting -10F, then consider yourself lucky. 

Check your door gaskets carefully.  This requires keen powers of observation.  Many times, I'll go to a house with this exact problem and it always turns out to be a door sealing problem.  They never believe me until I fix it and the problem goes away.   On a new fridge like yours, I'd suspect that the cabinet isn't square and this is creating a gap somewhere in the sealing surface.

Samurai, I've ran into this very issue with GE products in the past. It's certainly worth checking.

ge had a couple of top mount models with airflow problems. the fix was to replace the evap cover with a revised one along with a revised mother board. i think the new mother board forced the fan to run a little faster.

Arigato for the explanation on my freezer problem. I don't
quite understand why my freezer temp went from 0 to -10. Would air leak around the gasket cause this? Would a bad
defrost heater cause this frost buildup if my gaskets are okay? What about a bad thermostat allowing the compressor to run longer than it should. Would that lower my freezer temp?
Arigato again!

   It couldn't hurt to turn that thing off at the breaker for an hour.  Won't cost ya nut'n.  That fridge doesn't have a thermostat.  It's a computer running a program.  Always allow 24 hours for temps to stabilize every time you adjust the temperature.

Does your GE fridge have "Upfront Electronic Digital Display which displays exact temperatures for the fresh food and freezer compartments"?

If so, this fridge has electronic temperature sensors (NTC themistors) and electronic control board instead of mechanical thermostat.

The "electronic control" fridge usually controls the temp of the fresh food and the freezer independantly by 2 thermistors.

In your case, the "freezer" thermistor could be bad (either short-circuit or out-of-range)

The "frost" water could get into the "freezer" thermistor if the thermistor is "crack" and it will cause a "short-circuit". The control board thinks the freezer is not cold enough and continue to cool it to an abnormal low temp.

You may have to check the "freezer" thermistor according to the specification from GE manual.

   The force is strong in this one.  Hmmm..  Water/Ice/Moisture in the evaporator thermistor. 

    For years Good A/C techs have been installing "drip loops" in their fan motor wires to keep water from following the wire into the motor.  Might not be a bad idea look for, and add as needed to the evap thermistor, every time you have the evaporator cover removed.
