Hello Masajepa,
refering to the refrigerator's manual you might consider implementing a cleaning routine to keep it running and in shape. If there is a freezer-part included a defrosting routine may be useful as well. All should be defined in an SOP. In case of a technical failure which is unlikely to occur, an emergency routine should be described, too.
Kind regards,
Otto

Hi Masajepa. I don't know the rules exactly but personally I check it once a year.
