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.

Combi oven steam issues are commonly caused by: clogged steam generator or boiler scale buildup, failed heating element in the steam generator, water inlet valve problems, or steam nozzle blockages. Mineral scale from hard water is the most common culprit and can be prevented with regular descaling. A combi oven specialist should inspect the steam system as improper repairs can damage the boiler.
