If your cool room isn’t maintaining the right temperature, it’s more than just an inconvenience – it can quickly lead to stock losses, safety risks, and costly downtime. Whether you’re running a hospitality venue, retail store or production facility, a reliable cool room is essential for keeping your products fresh and safe.
So, what’s going wrong when it’s not cold enough?
Below, All So Cool have some of the most common issues – and what can be done to fix them.
1. Blocked or Dirty Condenser Coils
Over time, condenser coils can become clogged with dust, grease or debris – especially in busy kitchens or dusty environments. When coils are dirty, heat can’t escape efficiently, making it harder for your unit to cool down properly.
Fix: Regular cleaning of the condenser coils is essential. A scheduled maintenance plan can help ensure this is done before it becomes a problem. Having your refrigeration plant serviced by All So Cool at regular intervals will prevent the chance of a system breakdown.
2. Poor Door Seals
If the door seals (gaskets) are damaged, cracked, or not sealing properly, cold air can leak out and warm air can sneak in. This reduces the overall cooling efficiency and forces the unit to work harder than it should.
Fix: Check for cracks or gaps in the door seals. Replacing worn gaskets is a relatively inexpensive fix that can make a big difference.
3. Blocked Airflow
Cool rooms rely on proper airflow to maintain an even temperature. Overstocking, stacking products right up to the fans or vents, or placing items in front of the evaporator can obstruct air circulation.
Fix: Make sure items are stored with space around fans and vents. Educate staff on proper loading practices to avoid blocking airflow.
4. Refrigerant Issues
Low refrigerant levels or a refrigerant leak can drastically reduce cooling capacity. This is a more serious issue and often requires professional diagnosis and repair.
Fix: A qualified technician – like those at All So Cool, can test the system, identify leaks, and recharge the refrigerant if necessary. It’s important not to attempt this yourself due to the handling requirements of refrigerant gases.
5. Thermostat or Sensor Malfunction
If the thermostat is faulty or the sensor is out of calibration, your cool room might not be maintaining the correct temperature – even if everything else is running fine.
Fix: Technicians can test and recalibrate or replace faulty thermostats and sensors to restore accurate temperature control.
