Continuing to Monitor Performance...
Everything is still working well.
The temperature of the refrigerator has been running a bit too cold, so I am tweaking the value of "SetPointTemp" upward to achieve close to an actual 38 degree F inside reading.
All of my digital 'wonder-thermometers' are producing different results, so I am using my fall back lab-grade mercury column thermometer as a standard.
After the first tweak, the temperature went from sub 30 degrees F (difficult to read a mercury column at night) up to 35 degrees F.
I just adjusted SetPointTemp up two more degrees, which should get me to 37 F which would be good enough.
The LM355 was not calibrated, so the temperatures it indicates are not reflective of actual temps. Therefore, the mercury column thermometer is being used as a standard.
