Signs of a refrigerant leak: unit runs but doesn't reach temperature, ice buildup on evaporator coil, hissing or bubbling sounds from refrigerant lines, oily residue near connections or fittings, and higher than normal electricity consumption. Only EPA-certified technicians can legally handle refrigerant. If you suspect a leak, call a technician promptly — operating a refrigerator with low refrigerant damages the compressor.

High-temperature commercial dishwashers must reach 180°F (82°C) at the final rinse to achieve proper sanitization per NSF and health department standards. Low-temperature chemical sanitizing machines must maintain proper chemical concentrations (chlorine, iodine, or quaternary). If your high-temp machine isn't reaching 180°F, it's not properly sanitizing and may fail health inspection. Call a technician immediately.

Commercial ice machines should be professionally cleaned and sanitized every 6 months at minimum, or more frequently in hard water areas. The FDA Food Code requires ice machines to be clean and sanitized to prevent mold, slime, and bacterial growth. Between professional cleanings, staff should clean the exterior, ice bin, and scoop holder regularly. Many operators who skip cleaning face costly repairs from scale buildup and potential health code violations.
