Commercial refrigerators must maintain 40°F (4°C) or below for food safety compliance. Walk-in freezers should be at 0°F (-18°C) or below. Many food safety programs require refrigerators to run at 35-38°F for proper margin. If your unit struggles to maintain proper temperature, especially during busy service periods or in hot kitchen environments, call a technician — compressor capacity or refrigerant levels may be the issue.

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.
