Cold Room Fault Diagnostic Vault
Every fault below is a complete diagnostic guide — the symptoms to recognise, the immediate safety action, the likely causes, and the professional REYDS repair. Each fault is also available for every Cape Town location we serve.
Cold Room Not Cooling
Your cold room is running but the temperature won't drop to set point.
Cold Room Temperature Rising
Stored product temperature is climbing despite the plant appearing to run.
Freezer Room Not Freezing
The freezer is holding above -18°C and product is softening or thawing.
Compressor Failure
The heart of the refrigeration plant has failed — no cooling, possible electrical burnout.
Refrigerant Leak
System is losing gas — cooling capacity drops as charge falls.
Gas Loss
Refrigerant has escaped the system — the plant can no longer cool effectively.
Defrost Failure
Ice is building up on the evaporator because the defrost cycle isn't working.
Fan Motor Failure
An evaporator or condenser fan has stopped — airflow is gone and cooling collapses.
Controller Fault
The temperature controller is misreading, alarming falsely, or not controlling the plant.
Electrical Fault
A wiring, contactor, or control-circuit fault is preventing the plant from running correctly.
Cold Room Tripping Power
The cold room is tripping the breaker or RCD — a safety fault that must be found, not bypassed.
