The problem
A coil failure in an open-air merchandiser or reach-in case isn’t a slow problem. A case running warm starts losing product within hours, and most facilities teams don’t find out until a manager notices or a customer complains. By then the replacement decision is being made under time pressure, not strategically.
Older or discontinued case models compound the issue: there’s often no current part number to order against, only a guess based on the nearest catalog size.
