Samsung Dryer tS / t5 / tC / tO / t0 / tE / tE3 / tC5 / tCS / 1 tC / 1tC5 / 1tCS Error Code

Samsung identifies a clogged lint screen or vent system trapping heat as the most common cause. The family does not prove a temperature sensor has failed, and hidden vent work belongs with a qualified dryer-vent professional.

Applies to Samsung dryer with digital display

What the appliance detected

Detected condition

The dryer detected an issue with temperature or with the sensors that measure it.

What may contribute

Possible causes

  • A clogged removable lint screen.
  • A restricted exhaust vent system trapping heat in the dryer.
  • A temperature-measurement concern that remains after the documented airflow checks.

Start conservatively

Safe preliminary checks

Work in order and stop whenever a step is not supported by the documentation for your model.

  1. Record the exact code and model

    • Photograph or write down the exact display, preserving spaces and the difference between tO with the letter O and t0 with zero.
    • Samsung notes that a character resembling an upside-down F is intended to be a t. Confirm the full model number and owner manual.

  2. Stop for heat or fire warning signs

    • Stop using the dryer for smoke, a burning odor, scorching, sparking, unusual heat, or visible damage.
    • Let the dryer cool and contact the appropriate qualified professional rather than trying another cycle.

  3. Clean the removable lint screen

    • With the dryer off and cool, clean the removable lint screen according to the exact model documentation.
    • Reinstall it fully before any later supported use.

  4. Address the exhaust vent safely

    • With the dryer off, visually inspect only accessible external venting for crushing, kinks, or an obvious blockage.
    • If blockage is suspected or hidden vent cleaning is needed, do not operate the dryer; use a qualified dryer-vent cleaning professional.

Actions not recommended

  • Do not operate the dryer with a suspected blocked vent or attempt hidden duct cleaning through the appliance.
  • Do not remove panels, access sensors or wiring, test energized parts, or replace a temperature sensor based on the code alone.
  • Do not repeatedly reset a returning code; a reset does not clear a blocked vent and erases error history useful to a technician.

When to stop and request service

  • Use a qualified dryer-vent cleaning professional when the exhaust path may be restricted beyond the accessible external check.
  • Request appliance service if the error continues after the lint screen and exhaust vent have been addressed safely.
  • Stop immediately for smoke, burning odor, scorching, sparking, unusual heat, or visible damage.
