Samsung Dryer tS Error Code: Causes, Cost & Fix

What is the Samsung Dryer tS error?#

A tS code on your Samsung dryer is a temperature-sensor fault — the thermistor that reads the exhaust temperature has gone out of range, so the control board cannot trust it. Because heat control is a safety matter, the dryer's usual response is to cut the heating element and run without heat, which is why the classic symptom is a dryer that tumbles but leaves clothes damp. Occasionally the opposite happens and it runs hot because it cannot see the true temperature. There is no home hazard, but you should not run a heat cycle it cannot regulate. Start with a five-minute power cycle to rule out a glitch.

tS on a Samsung Dryer: likely causes and repair cost#

On a Samsung Dryer, the tS code signals: temperature sensor error.

Typical professional repair: $125–$275 · Difficulty: hard · usually a technician job

Symptoms that often accompany tS: Dryer runs but does not heat (shuts off heating element as a safety measure); Dryer overheats because it cannot read exhaust temperature; Cycle ends prematurely before clothes are dry; Error appears shortly after starting a cycle

Technician diagnostic sequence for tS:

1. Unplug the dryer and access the thermistor — on Samsung dryers, the exhaust thermistor is typically mounted on the blower housing or exhaust duct inside the machine
2. Disconnect the thermistor leads and test with a multimeter: at room temperature (77 °F) it should read approximately 10 k-ohm. At 150 °F it should read approximately 3-4 k-ohm. Open or shorted readings mean replacement is needed
3. Check the wiring from the thermistor to the main control board. Samsung dryer wiring runs along the inside panels and can be damaged by heat or vibration
4. Some Samsung models have two thermistors — an inlet sensor and an exhaust sensor. The tO variant specifically indicates the outlet (exhaust) thermistor. Identify which sensor the code references using the service manual

Parts a technician may check or replace: Samsung DC32-00007A; Samsung DC32-00008A; Thermistor wiring harness if damaged

Field note: Samsung displays "tS" and "t5" for the same error — the "S" looks like "5" on the seven-segment display. If a customer reports "t5" they mean the thermistor code, not a different error.

How to troubleshoot the tS error yourself#

The owner-safe checks on tS are modest. Power-cycle the dryer and start a timed cycle to see if the fault was transient. Clean the lint filter and make sure the exhaust vent is not blocked, because a badly restricted vent lets heat spike and can make a marginal sensor read wildly, mimicking tS. Beyond that, the causes in the table above — a failed thermistor and its wiring — are a "hard" repair: the sensor sits in the exhaust path, and confirming it means resistance-testing with a meter. That is where I hand off to a technician, both to test the thermistor correctly and to avoid replacing a sensor that a clogged vent was actually setting off.

Is the Samsung Dryer tS error worth fixing?#

tS is generally worth fixing on a dryer with life left. The table above lists $125 to $275 to replace the temperature sensor and restore proper heat regulation — a contained, mid-range repair. Against a new dryer that is a small share of the cost, so I fix it in most cases. Replacement only makes sense on an old machine already stacking failures; a lone tS on a sound dryer is comfortably worth the $125 to $275.

Samsung Dryer tS: frequently asked questions#

What does the tS error mean on a Samsung Dryer?#

It means the exhaust temperature sensor is out of range, so the dryer cannot regulate heat safely. It usually cuts the heating element, leaving clothes damp.

Is it safe to keep using a Samsung Dryer that shows the tS error?#

Avoid running heat cycles it cannot control — it may not heat, or occasionally overheat. There is no home hazard, but hold off until it is checked.

Can I clear the tS error myself, or do I need a technician?#

A power cycle and a vent/lint-filter cleaning are worthwhile first steps. A genuinely failed thermistor must be tested and replaced by a technician.

How much does it cost to repair the tS error on a Samsung Dryer?#

The table above lists $125 to $275 to diagnose and replace the temperature sensor.

Which parts usually fail when a dryer throws the tS code?#

The exhaust thermistor and its wiring, per the table above, with the sensor itself the leading cause.

Why does a thermistor failure trigger the tS error?#

When the sensor drifts out of spec or opens, the board reads an impossible exhaust temperature and cuts heat, flagging tS rather than run a cycle it cannot regulate.
