Thermador Built-in Refrigerator Evaporator Coil Replacement

Today we replaced a leaking evaporator coil in a Thermador refrigerator. The customer was noticing a slow increase in temperatures in the freezer and refrigerator. After basic checks, we removed the refrigerant, added nitrogen and checked for leaks. Sure enough, the evaporator coil had a leak, where the defrost heater had been touching the coil. Over time it caused the aluminum coil to weaken in that spot and slowly leak. We replaced the evaporator coil with a new one and it is working as good as new. Check out the photos and video.
