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.

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.

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.
