Sounds like you fixed the problem with defrosting.
The temperature problem you are having may be the refrigerator but it may also be your testing methods or your equipment. I use a Fluke 289 and a Fluke 80PK-25 Type-K Thermocouple into the customers icecream or anything with a large thermal mass in a liquid form. I use a Fluke 80BK-A Thermocouple for oven calibrations.
My dad is an engineer and says RTDs are more accurate but I think this is good enough. My thermocouples are all about a degree off from each other in a glass of ice water. It's within accepted limits for the industry.
