Reduced ice production is usually caused by: mineral scale buildup on evaporator plates reducing heat transfer, dirty condenser coils reducing refrigeration efficiency, warm ambient temperature in the equipment room, low refrigerant levels, or water flow problems. The fix for scale buildup is professional cleaning and descaling. Other issues require a technician. Never ignore reduced production — it often progresses to complete failure.

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.

The hi-limit switch is a safety device that cuts power when fryer temperature exceeds safe limits. Common causes: faulty thermostat allowing oil to overheat, failing hi-limit switch itself, improper temperature settings, low oil level exposing heating elements, or carbon buildup insulating heating elements. Never bypass the hi-limit switch — it prevents fires. Call a technician to diagnose the root cause.
