Samsung Dryer tS Error Code

Temperature sensor fault. What it means, which models show it, and how to clear it, easiest fix first.

SamsungAll Samsung dryer codes

tS
Moderate DIY

The dryer's temperature sensor (thermistor) is giving a reading the control cannot use. Parts guides say tS points to a shorted sensor and tO to an open one, but Samsung says lint is the usual culprit: a clogged lint screen or vent holds heat inside the dryer. A failed sensor, damaged wiring or the control board are the other possibilities.

Also shown as

Samsung groups tS, t5, tC, tO, t0, tE, tE3, tC5, tCS, 1 tC, 1tC5 and 1tCS together as temperature errors. A character that looks like an upside-down F is really a t.

Difficulty

Start with the safe checks below; a worn part may need replacing.

Safety first: unplug the dryer (or switch off its breaker) before touching filters, hoses or panels. If you smell burning or gas, or see water near the outlet, stop and call a professional.

How to fix Samsung tS

  1. Clean the lint screen and vent

    Clean the lint screen. Unplug the dryer, disconnect the exhaust hose and clear any lint from it and from the outlet on the back of the dryer. Make sure the outside vent flap opens freely.

  2. Restart

    With the vent clear, plug the dryer back in and run a cycle to see whether the code returns.

When to call a technician

If the code returns with a clean lint screen and vent, book a repair so a technician can test the thermistor and its wiring.

Often. The first steps above are safe checks a homeowner can do. If they don't clear tS, the cause is likely a worn part that needs replacing.
