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.

Commercial refrigerators must maintain 40°F (4°C) or below for food safety compliance. Walk-in freezers should be at 0°F (-18°C) or below. Many food safety programs require refrigerators to run at 35-38°F for proper margin. If your unit struggles to maintain proper temperature, especially during busy service periods or in hot kitchen environments, call a technician — compressor capacity or refrigerant levels may be the issue.

Ice quality issues often indicate water system or refrigeration problems: cloudy ice suggests poor water quality or mineral content; soft ice indicates inadequate freeze cycle time or refrigerant issues; small or misshapen cubes typically point to low water flow, scale buildup on evaporator plates, or refrigerant problems. All of these issues affect the safety and quality of ice used in beverages and food service.
