The customers were concerned that the freezer temperature was getting up in the 20s at times. As advised a customer it was probably happening during the defrost and theres nothing to worry about. I did find that the freezer door was not sealing tight all the way and that was letting moisture into the freezer. I adjusted the freezer door hinges so the door does not rub and shuts better and I put some grease on the freezer door gasket.
