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.

Hood cleaning costs range from $300 to $1,500+ depending on system size, grease accumulation, and accessibility. Small single-hood systems run $300-$500; larger multi-hood systems or restaurants with heavy cooking can run $700-$1,500. Access issues (long duct runs, high roofs) add cost. Budget for cleaning as a fixed operating expense — it's far less expensive than a grease fire, insurance claims, or health violations.
