Walk-in door gaskets typically last 2-4 years and should be inspected every 6 months. Signs of failing gaskets: visible tears or cracks, frost buildup near the door frame, condensation on the door frame, noticeably warmer temperatures near the door, or the door not staying closed. A failing gasket forces the compressor to work harder, increasing energy costs and reducing equipment life.

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.

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.
