Encased in ice, would be the evaporator. The condensor gets hot. Other than that, it's progress. At least you have a general idea what's going on.

First update.
On the second repair visit, the tech placed an order for a new CPU unit. In the intervening days, a package arrived from GE's parts warehouse.
On the appointed day, a different tech arrived (I was no in the house that dya) and told the family that the first tech had ordered the wrong part (it said "inverter unit" on the box). Freezer temperature now hovering about 20 and, for the first time, refrigerator temp consistently above set point too.
They shoved the list of things to check (suggested here) under his nose. He removed the back wall of the freezer compartment to reveal the condenser encased in ice. So it's a defrost problem - suggested here - and we noted the temperatures are highest on the days with the most humidity.
More parts ordered - return visit sched for tomorrow (Tuesday 7/24).
