Cold Room Running Warm
A cold room running warm — but not completely failed — usually points to an efficiency problem: low refrigerant, a fouled condenser, a failing compressor or a defrost issue. Left unchecked it becomes a full breakdown. We diagnose the efficiency loss and restore correct temperature.
What causes cold room running warm
- Low refrigerant charge from a slow leak
- Dirty or blocked condenser coil
- Compressor losing capacity
- Defrost cycle not clearing ice
- Warm air ingress through damaged seals
- Evaporator fan running slow
- Incorrect controller settings
How we diagnose this fault
Compare setpoint vs actual temperature
Measure superheat and subcooling
Inspect condenser condition and airflow
Check defrost frequency and duration
Test door seals and panel joints
Review controller programming
How we repair it
