Started with warm refrigerator - both freezer and fridge.
Tech came and after a weeks wait - replaced the lower evaporator coil assembly

Since then fridge only held temperature for couple of days.
- Tech refilled gas, but again back to not holding temperature.
- Still cools but Freezer at 12 and Fridge at 54 ..not 0 and 39.
- Ice trays hold ice in the freezer, but frozen food is not ice cold.
- Fan is working

Opened the back panel.
Lots of solid ice buildup in the right corner side
- Absolutely, no ice in/around the drain hole this time or the bottom of coils

Used hair dryer to melt the ice.
Had the freezer ON for 4hrs and re-checked the coils- Again build up of ice on the right top capillary?



What was missed or can it be fixed?

Looks like a freon leak or a compressor problem.

You said what the original symptom was but not what the actual problem was re: a leak in the evaporator or somewhere else.

the original problem was not cooling one fine day. It might have been gradual that we didn't notice.
The tech came and checked the compressor and fan - but nothing inside the freezer back panel. He suggested it was a great fridge and a replacement of lower evaporator coil will make it like brand new.
So we went ahead with the part replacement.
After the replacement there has been frost build up on the freezer back panel
Inside is as shown in the posted pictures
We are still able to use it as its cold enough, but not reaching 0 or 39F as indicated on control.

Any ideas why the ice is builup (within 4hrs)on that specific tube ? Was it part of the coil replacement, not soldered properly or anything missed?
Sad to have invested so much in this and end up in junkyard.

Normally the fresh food evaporator is the one that leaks

Did you get some type of warranty for the repair?

Also I cannot find any info on the given model number.

Your refrigerator is low on refrigerant.  Proof is that the entire evaporator (cooling tubes) should have a thin and even coat of frost while running.  When sealed system is losing gas, frost occurs on only part of the evaporator right after the capillary tube.  If the system has too much gas, frost will continue right on down to the compressor.
