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.

Installation time varies significantly: single appliance with existing connections 2-4 hours; single appliance requiring new utility connections 4-8 hours; full kitchen buildout 1-3 weeks depending on scope, permit timelines, and contractor scheduling. Work with your installer to create a realistic timeline that accounts for utility work, inspections, and health department walkthroughs before opening.

Common causes include: faulty igniter or ignition module, failed heating element (electric ovens), thermostat or temperature probe failure, gas valve issues, or clogged burner ports. Start by checking error codes on the control panel if equipped. If the oven lights but doesn't reach temperature, the thermostat or temperature probe is often the culprit. A certified technician can diagnose the root cause quickly.
