6.2  Troubleshooting via symptoms

Symptom

Possible cause

Corrective action

Low cooling power - too 

high temperature in the 

cooled object

The power supply has been interrupted.

Check the control/safety switches and 

fuses. 

No air flow or too low air flow across 

evaporator.

Check that nothing is inhibiting the air 

flow.

The control equipment is incorrectly pre-

set/defective

Adjust the settings or replace the 

equipment.

Compressor is not op-

erating

The power supply has been interrupted.

Check the control/safety switches and 

fuses.

Compressor has opened a safety circuit. Check and reset, if needed.

Defective compressor

Check/replace

Frost on the evaporator

The expansion valve is incorrectly preset/

defective

Check/replace

Insufficient refrigerant volume

Search to detect leakage, seal the leak 

and charge with refrigerant

Low supply air flow

Adjust the flow

Alarm reset

In the event of an alarm initiated by the frequency inverter or the safety circuit, 

the compressor stops and the sum alarm relay is energised. The alarm is dis-

played in the control unit menus “Operating information, compressors” and 

“Status: Alarm”. 

In the event of an alarm, take corrective action to correct the fault, and then 

press the “Alarm reset” button on the control unit for 3 seconds. If the safety cir-

cuit alarm trips repeatedly, an authorised refrigeration service company must be 

called in.
