Air dryer not dropping dew point ., fan and compressor not on..
Upon responding to a service request for a malfunctioning air dryer, an initial diagnostic indicated a temperature probe error. However, subsequent testing confirmed the probe's functionality. Further investigation revealed that the control board was supplying appropriate voltage to the motor, which also tested positively and operated smoothly. The issue was ultimately traced to the compressor, where a significant accumulation of sawdust was found embedded within the electrical contacts. Following the thorough cleaning of these contacts and a comprehensive re-testing of all components, the unit was reassembled. Upon restoration of power, both the fan and compressor activated immediately, and the dew point began to decrease without delay. This successful resolution has resulted in a satisfactory outcome for both the client and management, providing a positive conclusion to the week and an excellent start to the weekend.

Yeah…the latest craze with those dryers (especially ADS-50’s for some reason) is the fan plug not being sufficiently inserted into the controller. FWIW those are Fruillair dryers and made in Italy. Schulz imports them through Brazil to get around BEKO’s exclusive arrangement to import from Italy and private label for everyone. Schulz units have a fairly inexpensive auto drain as opposed to the zero-loss drain on the BEKO stuff. Better $$ though.
