Introduction
Cold rooms are the backbone of many Cape Town businesses—from restaurants and butcheries to supermarkets and caterers. But when a cold room stops cooling properly, it can quickly turn into a crisis.
While many issues require a technician, there are a few things you can check yourself before calling for professional help. At Paradigm Cooling, we recommend the following troubleshooting steps to businesses in Claremont, Wynberg, Rondebosch, and Tokai.
1. Check the Power Supply
Load shedding and tripped breakers are common culprits in Cape Town. Always confirm your cold room has power before panicking.
2. Inspect the Thermostat Settings
Ensure the temperature setting hasn’t been accidentally changed. Cold rooms should generally stay between 2–5°C for refrigeration and -18°C or lower for freezing.
3. Examine Door Seals
If seals are cracked or damaged, cold air escapes and warm air enters. This forces the system to overwork and may cause uneven cooling.
4. Look for Obstructions to Airflow
Blocked shelves or overstocking can prevent cold air from circulating evenly. Make sure fans and vents aren’t obstructed.
5. Check for Ice Build-Up
If coils are iced over, the defrost cycle may not be working. Excess ice reduces efficiency and can even stop cooling completely.
6. Listen for Unusual Noises
Strange sounds may indicate motor or fan issues. Document the noise—it helps technicians diagnose faster.
7. Inspect the Condenser Unit
Outdoor condensers can become clogged with dust, debris, or Cape Town’s coastal salt. Clean gently with a brush or water spray.
8. Monitor Temperature Trends
If temperatures rise gradually, it may be a minor issue. If they spike suddenly, it’s likely a serious fault.
When to Call a Technician
If problems persist after these checks, it’s time to call Paradigm Cooling. Professional diagnostics can identify issues such as:
- Refrigerant leaks
- Compressor faults
- Electrical problems
- Defrost system failure
