A display fridge that isn't maintaining temperature can quickly become a serious problem for cafés, supermarkets, dairies and food retailers. Not only can products become unsafe, but the refrigeration system usually works much harder while trying to compensate.
Finding the cause early can often prevent more expensive repairs.
Check the Doors First
Door seals, damaged hinges or doors left open allow warm air to enter continuously.
This is one of the simplest problems to identify and one of the most common.
Blocked Airflow
Products stacked too closely against internal vents restrict airflow through the cabinet.
Cold air needs to circulate freely around the displayed products for even cooling.
Dirty Condenser
Dust and debris on the condenser reduce the system's ability to reject heat.
The compressor runs longer, electricity use increases and cabinet temperatures begin to rise.
Mechanical Faults
If airflow and door seals appear normal, the refrigeration system itself may require inspection.
Refrigerant leaks, faulty fans, temperature sensors or compressor problems can all reduce cooling performance.
When Should You Contact Holmes Services?
Book a refrigeration service if:
- Products are no longer staying cold.
- The compressor runs almost continuously.
- Ice develops unexpectedly.
- Error codes appear.
- The cabinet temperature keeps increasing.
Prompt repairs help reduce product loss and minimise business disruption.
Frequently asked questions
Can overloading a display fridge make it warmer?
Yes. Blocking airflow prevents cold air from circulating properly.
Should I lower the thermostat?
Changing the temperature setting rarely fixes an underlying
refrigeration fault.

unexpected breakdowns.
