What to do if my VARON NT-04 Medical Equipment makes abnormal working sound?
- T
  Troy GutierrezAug 5, 2025
  If your VARON Medical Equipment exhibits an abnormal working sound after powering on, it could be due to several reasons. First, it might be a compressor failure, in which case you should disconnect the power supply and have it repaired by professional maintenance personnel. Secondly, the ambient temperature may be too high, activating the self-protection program of the oil-free compressor. This is normal, and the machine will restart automatically when the temperature lowers. Finally, the connecting tube inside the machine might be disconnected or broken, requiring you to disconnect the power supply and seek professional maintenance.

  If your VARON Medical Equipment has a small flow rate after starting, it could be due to a few reasons. The flow rate level might be set too low, so try turning it up. Alternatively, the tube might be twisted or blocked, in which case you should straighten it. Finally, the connecting tube inside the machine could be disconnected or broken, requiring you to disconnect the power supply and have it repaired by professional maintenance personnel.
