Samsung Dryer Error Code C90: Meaning and Fix
Also shown as: C9, C9o
Reading the dryer display
On a dryer the code shows in the time-remaining window or as blinking status lights. Write down the characters before you press anything, because starting a new cycle usually clears the display. Samsung codes combine a digit with a letter, and some alternate with the cycle time.
Samsung displays numeric-plus-letter codes such as 4C, 5E or 21E, and many models run a Smart Care self-check through the app. Washers and dryers often use letter pairs, refrigerators use number plus E. The codes apply to model numbers such as DW80R5061US, DW80K7050US and DV45T6000EW; check the label on your unit to confirm yours.
What causes C90
- Heavy lint plug in the duct
- Collapsed vent hose
- Bird nest or debris at the exit
- Blocked outside hood
How to fix it
- Stop using the dryer until the vent is cleared.
- Disconnect and fully clean the duct from dryer to outside.
- Replace any crushed or damaged duct.
- Remove any nest or debris at the hood and make sure the flap opens.
- Rerun the test.
