hi guys i'm using digicabi 30L. i have been moitoring the cabinet for months since i bought it. i adjusted the knob to abt 11:30 o'clock position and i get it stablised at abt 45% for few days with the green light dim to near no light. after few days, the RH will increase to as high as 70+ or 80+% with the green LED at brightest for up to a week or 2 then back to abt 45% with dim green light and the cycle goes on. Is my cabinet normal? I need some advise before i send the dehumidifier for RMA.
