Commercial cooler decision guide
Protect people and product before troubleshooting equipment.
If a walk-in cooler is not holding temperature, follow the business’s food-safety procedures, minimize unnecessary door opening, record what you can safely observe, and contact an appropriate professional. Do not attempt refrigerant or live-electrical work.
Immediate steps

- Follow the facility’s food-safety and incident procedures.

- Record food and equipment readings separately, including time and measurement location.
- Note alarms, visible ice or water, door condition, sounds, and when the change began.
- Move or dispose of food only under the business’s approved procedures and applicable health guidance.
- Contact an appropriate refrigeration professional for equipment diagnosis.

Questions
Commercial refrigeration request FAQs.
Is the cooler display enough to decide whether food is safe?

Should I keep opening the door to check?
Limit unnecessary door opening while the condition is being evaluated. Record observations safely and follow the facility’s procedures.
Can this guide diagnose the cause?
