Found box temp on Walk-In Freezer at 16 degrees. Front of evap froze over only one evap fan running. Freezer filled with product could not get to evap. Customer moved product. Removed guards and blades and defrosted coil and motors. Put evap back together and ran two evap fans faulty from being caught in ice. Will need two new motors. Also found door leading outside to not have a sweep and can see right under door 1 inch gap will need sweep. Called manufacturer for part numbers and new fan motors are a retrofit and will need holes drilled to install. Spoke with manager and he said OK to order need by Friday. 8/14/20 Removed faulty motors and installed new retrofit motors and door sweep. Tested operation, OK
