New freezer, temps not responding well (updated title)

I have a BrewPi RevC on an Arduino Uno that I have been running for some time. My chamber was a glass front wine cooler that worked fairly well to start. As time went on the cooler just could not cool and was running almost full time just to get ‘close’ to my profile temperatures. I finally purchased a new upright freezer and have just switched it out.
It seems the BrewPi is struggling to adapt to the new freezer and I’m not sure how to help it’s settings.
Any suggestions where to start?
