Any ideas what would to check that would cause a weak airflow?

Without any resolution, I'm playing detective:
1. I noticed the face of the door between the fridge and the freezer is warm.
2. In checking the compressor, I found it really hot to the touch.
Are these helpful symptoms or just the result of the fridge running at max setting to keep it at 40 degrees?

Check the evaporator motor, it might be running backwards. It must turn the fan blade in the proper direction to cup the air and force it out at high speed.

Opened the freezer back and the evaporator fan is moving a good airflow in the proper direction. Frost pattern on the coils is uniform and very light. No ice at all. I disassembled all the way up to the diffuser into the fridge and there were no obstructions. I noticed the baffle directs some air to the ice maker and some to the diffuser. The freezer has continued good ice production. Does this indicate adequate air flow at least on the freezer side? Any other ideas??

You probably have weak airflow into the fridg section. Checked the temp right at the diffuser again last night and may have given a false reading. After about 45 minutes directly in front of the diffuser, the thermometer read 22 degrees. As I picked it up to move it I bumped it and it dropped to 10 degrees. In a month of use, I've never seen the thermometer change reading as I moved it. Is it possible that my mechanical thermometer stuck at 20 degrees and gave a false reading due to being directly in the air flow?

Clean the condenser coils and check the condensing fan, something is wrong here.

I really appreciate your help figuring out what is wrong Condenser coils are cleaned regularly, and were cleaned well at the start of this fiasco. I cleaned them again over the weekend when I was doing my own inspection. The repairman did say on his first visit that the condenser fan wasn't drawing well so he tweaked the fan blades for better flow. The fan is doing a good job pulling air away from the coils and compressor, pushing air out over the defrost water collection tray (from the defrost cycle). Is this the correct direction of air flow?

You just might have a worn compressor. To confirm, I would get a good thermometer and measure the evaporator temperature coming out of the top of the evaporator, should be between zero, and 10 degrees; if not, either you have contaminated refrigerant, a weak compressor, or insufficient charge. If you listen to the compressor running, and you hear unusual noises periodically, that is either non-compressable air, or the compressor periodically failing.

If you listen to the compressor running, and you hear unusual noises periodically, that is either non-compressable air, or the compressor periodically failing. No unusual compressor noises. Repairman drained serviced and recharged the system 24 hours ago. No change or improvement. What is a 'weak compressor' and what are the chances a compressor replacement will fix it?
