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.

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.

1) Call an emergency refrigeration technician immediately. 2) Take and document temperature readings. 3) Move the most temperature-sensitive items (proteins, dairy) to alternate refrigeration first. 4) Contact your health department if temperatures approach 40°F+ — they can advise on food safety decisions. 5) Document all food temps for insurance claims. 6) Consider dry ice or portable refrigeration units for critical inventory. 7) Alert your supplier you may need emergency replacement products.
