Wouldn’t it be nice to work on a piece of equipment such as an icemaker, and know exactly what had been done to the unit in the past? Equipment logs can help you identify what other service techs have done, or maybe even what you did to the unit last summer during those 12- or 14-hr days.
This type of information can be recorded in a journal that includes complete model and serial numbers, installation date (for warranty validation), what type of work was done, operating specifications, and so on. This notebook can be kept at the machine, on your truck, or back at the office.
