Fire-N-Ice Heating and Air Conditioning

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.

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.

Yes — most food service operators find PM contracts reduce total repair costs by 30-50% compared to reactive-only maintenance. Benefits include: reduced emergency repair calls (the most expensive type), extended equipment lifespan, maintained food safety compliance, priority scheduling for PM customers, and detailed maintenance records for health inspections. The ROI is especially strong for high-volume operations where any downtime is costly.
