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.

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.

Commercial ice machines should be professionally cleaned and sanitized every 6 months at minimum, or more frequently in hard water areas. The FDA Food Code requires ice machines to be clean and sanitized to prevent mold, slime, and bacterial growth. Between professional cleanings, staff should clean the exterior, ice bin, and scoop holder regularly. Many operators who skip cleaning face costly repairs from scale buildup and potential health code violations.
