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.

CFESA (Commercial Food Equipment Service Association) certification is the industry standard for commercial kitchen equipment technicians. Certified technicians have passed rigorous examinations on electrical, refrigeration, and gas systems. When you hire a CFESA-certified tech, you can trust they have the knowledge to properly diagnose and repair commercial kitchen equipment safely and effectively.
