The hi-limit switch is a safety device that cuts power when fryer temperature exceeds safe limits. Common causes: faulty thermostat allowing oil to overheat, failing hi-limit switch itself, improper temperature settings, low oil level exposing heating elements, or carbon buildup insulating heating elements. Never bypass the hi-limit switch — it prevents fires. Call a technician to diagnose the root cause.

Commercial kitchen equipment lifespans vary: commercial ovens 15-20 years, fryers 10-15 years, refrigeration equipment 10-15 years, ice machines 7-10 years, dishwashers 10-15 years, steam tables 10-15 years. Regular preventive maintenance significantly extends equipment life. Equipment that is properly maintained often outlasts these averages by 5+ years.

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.
