1. Power
Check the plug, breaker and display. Do not repeatedly reset a breaker that trips again.
SAFE DIY CHECKS
Commercial refrigerator not cooling: check these five points first
These checks are for business-use refrigerators and freezers. They help identify simple external causes; they do not replace pressure, current, leak or electrical testing by a technician.
Commercial equipment only — we do not repair household refrigerators.
Five checks
2. Temperature setting
Confirm the setpoint and whether the unit is in defrost, standby or an alarm state.
3. Door closure
Remove anything blocking the door and inspect the gasket for gaps or damage.
4. Airflow
Keep product away from internal air outlets and check for heavy frost around the evaporator.
5. Condenser
If safely accessible, check whether dust or grease is blocking heat rejection. Do not disassemble live equipment.
Stop and call a technician
Stop immediately
Stop the unit if there is smoke, burning smell, exposed wiring, repeated tripping or severe mechanical noise and it is safe to do so.
Arrange inspection
Call when the temperature continues rising, frost quickly returns, refrigerant piping is oily, or the compressor and fans do not operate normally.
Send useful evidence
Send the model plate, display, current and set temperatures, full-unit photo and fault video on LINE.
Common questions
Can I add refrigerant myself?
No. Refrigerant work requires leak diagnosis, suitable tools and trained handling, especially for R290 and R600a systems.
Should I keep restarting the unit?
No. Repeated restarting can hide the fault or stress electrical and compressor components.
When should food be moved?
Move or protect stock when the product temperature can no longer be kept within the required safe range.
Need help with commercial refrigeration equipment?
