Thanks! YES, that is what I was looking for. Since the unit was still under warranty, I called a service tech to come have a look.
The first thing he did was to open the Left French Door of the Refrig, take out the Ice Cube box, and look at the Frosted and Iced
up Fan. From there he left it to me to somehow Defrost it, and call back if it didn't start making Ice.
Things I learned about making Ice in the Top of my Refrigerator:
1. The Ice Box has a small Evaporator Coil in series with the Real Evaporator Coil, and the Ice Maker (IM) Fan must be operational.
There is also a Defrost Heater Coil, and a Temperature Switch that controls the Defrosting.
2. The Freezer and Refrigerator Settings a typical user can access are SETPOINTS, and NOT a Temperature Display.
3. Actual Temperatures of Refrig and Freezer must be accessed by Diagnostic Menu Items #29 & #30.
It would appear that a typical user would need to know the Refrig and Freezer Temperature on the Display, and that the
SETPOINTS for Refrig & Freezer would be Factory set in the Diagnostic Menu, since folks don't need to change them hourly, daily, weekly
and otherwise have no clue as to actual Temperatures inside the unit.
4. If the Actual Refrig & Freezer Temperatures are not within +-X (~4 Degrees) of a SETPOINT, it doesn't make Ice..PERIOD!
5. If the IM Fan isn't running, it doesn't make Ice..PERIOD!
6. If the IM Evaporator is FROZEN UP, it's a bitch to defrost, but possible, without full disassembly. No Clues in the Service Manual!
7. If you disassemble, you need the FGHB28 Service Flash Gasket Kit to properly repair the unit for re-assembly.
8. It takes a LONG time for the IM to recover, as each tray takes a multitude of hours before another Harvest completes.
9. The Service Manual covers THREE different Ice Makers for this Refrigerator.
Fresh Food Compartment Ice Maker (Flex Tray)
Fresh Food Compartment Ice Maker (Finger Evaporator)
Freezer Ice Maker
At least it's making Ice.
