Reliable equipment care starts with regular observation and an appropriate response. Use this guide as general education, then follow manufacturer instructions and seek qualified advice for your particular site.
Protect people first
If there is smoke, a burning smell, exposed wiring, sparking or another immediate hazard, keep people clear and contact emergency services where appropriate. Do not repeatedly reset a breaker or bypass a safety device.
Keep the cold in
Minimise door opening and move temperature-sensitive stock only according to your documented contingency plan. Record temperatures and times. Do not make assumptions about food safety; follow your plan and relevant authority guidance.
Capture useful information
Note alarm codes, unusual sounds, when the fault started and any recent work or power interruption. Photograph the display if safe. Do not dismantle the equipment, as that can create hazards and remove diagnostic clues.
Call with clear details
Give the service provider your site address, contact person, equipment type, symptoms and business impact. After recovery, review the cause and update the emergency plan, asset register and maintenance schedule.
Never bypass a safety device or attempt electrical or refrigerant work unless you are properly qualified and authorised. Protect people first.
