Responded to an emergency request from one of our commercial customers in Fair Oaks California. One of their Traulsen freezers was not going into proper defrost or so the employees thought. After troubleshooting the system, our tech found that the unit was hitting proper defrost and standard temperatures, but that the display was faulty and not showing the temperatures correctly. Will source and order a new display for the freezer. Unit is functional and can be used to store product in the meantime.
