Hi to all !
I have a problem with Samsung inverter air conditioners, models are UH105 EAV and UH 140 GAV-outdoor units. Five out of 20 units installed in the same building show error 461. After going trough service manual and checking compressors next step is replacing out door units inverter PCB, as read in service manual.
If any one had the same problem I would like to know if replacing the PCBs solved their problem and possible cause of malfunction, my guess is low voltage but cant confirm it without grid voltage recording.
