Signs your oven needs calibration: food is consistently undercooked or overcooked at standard settings, cooking times are significantly longer or shorter than expected, the displayed temperature doesn't match an independent thermometer reading. Oven calibration should be part of every service visit and can drift over time from component wear. A variance of more than 25°F warrants professional calibration.

Yes — most food service operators find PM contracts reduce total repair costs by 30-50% compared to reactive-only maintenance. Benefits include: reduced emergency repair calls (the most expensive type), extended equipment lifespan, maintained food safety compliance, priority scheduling for PM customers, and detailed maintenance records for health inspections. The ROI is especially strong for high-volume operations where any downtime is costly.

Consider replacement when: repair costs exceed 50% of replacement cost, the equipment is over 75% of its expected lifespan, parts are no longer available, the equipment frequently breaks down, or energy costs are significantly higher than modern alternatives. Repair when: the equipment is relatively new, the repair is straightforward, and the total repair cost is well below replacement value. A qualified technician can help evaluate your specific situation.
