  If your Pfannenberg Accessories unit isn't cooling sufficiently, several factors could be at play. First, ensure that the ambient temperature and internal load do not exceed the unit's capacity. A dirty filter or condenser can also reduce cooling efficiency, so clean the condenser. Other potential issues include malfunctioning internal and external fans, which may require checking the fan capacitors and replacing the fans if necessary. Additionally, make sure that air is circulating properly inside the switch cabinet by ensuring proper electrical connections, and verify that the air intake and exhaust are not blocked by any components. If the issue persists, it may be due to a lack of refrigerant, in which case you should call an authorized technician.

  If the compressor is ON, the internal and external fans are ON, the status LED is flashing (seq. 1), and the fault signal contact is open in your Pfannenberg Accessories unit, it means that the upper temperature limit of the switch cabinet has been exceeded. You should clean the filter mat or heat exchanger in the external circulation. Also, check the power dissipation in the switch cabinet relative to the cooling capacity of the cooling unit.
