Preventive maintenance frequency depends on the equipment and usage volume. As a general guideline: fryers and ovens should be inspected every 3-6 months; refrigeration equipment annually or semi-annually; ice machines every 6 months (including cleaning and sanitizing); exhaust hoods quarterly to semi-annually per NFPA 96; and dishwashers quarterly. High-volume operations benefit from more frequent service intervals.

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.

Commercial fryer safety checks include: verifying hi-limit switch operation, checking thermostat accuracy, inspecting gas connections and pressure (gas fryers), testing electrical connections (electric fryers), checking oil filtration system function, inspecting drain valve operation, verifying fire suppression system compatibility, and checking for oil leaks. Safety checks should be performed by a certified technician at every service visit.
