A comprehensive PM program should include: scheduled inspections at manufacturer-recommended intervals, cleaning of condenser coils and filters, calibration of temperature controls, inspection and testing of safety systems, lubrication of moving parts, replacement of wear items (gaskets, filters, belts), refrigerant level checks, combustion analysis for gas equipment, and detailed documentation for each visit. Avoid programs that are just a visual inspection without hands-on service.

Kitchen equipment emergencies include: walk-in cooler/freezer temperature rising (food inventory at risk), gas leak or smell, fire suppression system discharge, electrical sparks or burning smells, complete loss of cooking equipment during service hours, dishwasher failure during a busy shift, or any situation creating an immediate food safety risk. These situations require immediate professional attention and may require temporary closure.

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.
