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.

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.

Walk-in door gaskets typically last 2-4 years and should be inspected every 6 months. Signs of failing gaskets: visible tears or cracks, frost buildup near the door frame, condensation on the door frame, noticeably warmer temperatures near the door, or the door not staying closed. A failing gasket forces the compressor to work harder, increasing energy costs and reducing equipment life.
