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.

1) Check if the condenser unit is running. 2) Inspect condenser coils for dirt and debris — blocked coils are a common cause. 3) Ensure walk-in door gaskets are sealing properly. 4) Check if evaporator fan is running. 5) Look for ice buildup on evaporator coils (defrost system failure). If temperature is rising significantly, move temperature-sensitive inventory and call a technician immediately — this is an emergency situation.

1) Do NOT operate any electrical switches, phones inside, or create any sparks. 2) Evacuate all staff and customers immediately. 3) Call 911 from outside the building. 4) Call your gas company's emergency line. 5) Do NOT re-enter until emergency responders clear the building. 6) Contact a certified kitchen equipment technician to inspect and repair gas connections before reopening. Gas leaks can cause explosions — always take them seriously.
