Chemical dispensing problems are typically caused by: clogged or faulty chemical pumps, incorrect dilution ratios, empty chemical containers, broken injection lines, or control board issues. In low-temperature machines, proper chemical concentration is essential for sanitization — test strips should verify concentration after every repair. Many chemical distributors offer free testing; alternatively, a technician can verify and repair the dispensing system.

Signs of a refrigerant leak: unit runs but doesn't reach temperature, ice buildup on evaporator coil, hissing or bubbling sounds from refrigerant lines, oily residue near connections or fittings, and higher than normal electricity consumption. Only EPA-certified technicians can legally handle refrigerant. If you suspect a leak, call a technician promptly — operating a refrigerator with low refrigerant damages the compressor.

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.
