No cooling either compartment, compressor and all fans sound normal
Sudden complete loss of cooling both compartments, despite that (multi-speed inverter) compressor, consenser, and both evaporator cooling fans run and sound normal continuously. Test modes produce no error codes on control panel nor inverter control board (solid compressor L.E.D., no blink codes). Condenser never gets warm and neither evaporator ever gets cold. Wondering if leak caused total loss of refrigerant, but then wouldn't compressor sound unusual, not run, or run only for short intervals? Or could refrigerant flow be restricted somewhere (perhaps at the 3-way stepper-motor diverter valve) without causing compressor to sound or act abnormally? Or is this just the way these compressors (Samsung MKV190C-L2B E01) fail? I'm puzzled, and would appreciate any knowledgeable help in diagnosing my problem. Want to know for myself what's most likely wrong before I call a technician. I have control system background, but in electro-mechanical systems vs. refrigeration. Thanks!
Ist dies eine gute Frage?
Did you ever figure this out? Same thing is happening to my Refrigerator.
Just replaced the compressor and filter drier pulled a vacuum and added 200g of freon.
It didn’t product any cooling at all. Compressor was running I heard at least 2 different speeds, 85 degrees but condenser not warm and evaporators not cold.
I blue through the cap tube before I connected the filter drier, it didn’t sound obstructed, I heard the air go through the line and sounded like it went back into the compressor however, the other 3 cap lines not sure if they are obstructed.
When I power it on, the 3 way valve vibrates a few times but then stops, I assume its operating. It does this every few minutes, vibrates a few times.
