Thermistor short circuit — temperature sensor reading too low resistance

The most common cause of the tS error on a Samsung dryer is failed (shorted) thermistor (~60% of cases); start with: test the thermistor.

What Does Error Code tS Mean on a Samsung Dryer?

Thermistor short circuit — temperature sensor reading too low resistance.

The main control board monitors the exhaust thermistor's resistance to manage drying heat. tS fires when that circuit measures near-zero resistance — a short — so the board can no longer trust the temperature reading and halts heating as a safety response. Unlike tO or tE (open or general thermistor faults), tS specifically indicates a shorted sensor or a harness wire chafed to ground, distinct from the overheat-related HE code.

Models affected: Samsung electric and gas dryers using an exhaust thermistor for heat regulation, including models such as DVE45R6100C, DVE45T6000W, DV42H5000EW, DVE50BG8300V, and DVG45T3200W
What owners report: Owners commonly report tS appearing mid-cycle with the drum still turning but no heat, and it often traces to a cheap, quick thermistor swap. A pinched or grounded harness wire can be a false trigger that mimics a bad sensor, so metering the wiring before replacing parts is worth the few minutes.

What Causes Error Code tS?

Here are the most common causes in order of frequency. Start with the most likely cause before moving to the next:

  1. 1
    Failed (shorted) thermistor 60% of cases
  2. 2
    Harness wire pinched or chafed to ground 25% of cases
  3. 3
    Connector corrosion at the sensor 15% of cases

How to Fix Samsung Dryer Error Code tS

🔧 Easy DIY Est. time: 10–20 min
⚡ Safety first: Unplug the appliance before opening any panels or touching internal components.
  1. 1

    Test the thermistor

    Unplug the dryer, remove the back or lower front panel, and measure the thermistor on the heater/blower housing: about 10kΩ at room temperature. Near 0Ω confirms tS.

  2. 2

    Inspect the harness

    Trace the two sensor wires for pinch points where panels were assembled, and check the connector pins.

  3. 3

    Replace the thermistor

    Two screws and a connector — one of the cheapest, easiest dryer repairs.

    ⚠️ Unplug the dryer before removing panels.

How to Reset Error Code tS

After replacement, plug back in and run a Time Dry cycle on medium heat to confirm normal operation.

Note: If the error returns after resetting, the underlying issue has not been resolved. Work through the fix steps above.

When to Call a Professional

If a new thermistor still reads shorted at the board connector, the harness or main board input has failed — meter the harness before buying a board.

Average professional repair cost for this issue: $130–$250

Frequently Asked Questions

Can I keep using my Samsung Dryer when error tS appears? +
You often can for a cycle or two, but the sensor issue behind tS will keep interrupting normal operation until it is fixed. Plan the repair rather than ignoring the code.
What most commonly causes tS on a Samsung Dryer? +
Across reported Samsung dryer repairs, the most frequent is failed (shorted) thermistor (60% of cases), harness wire pinched or chafed to ground (25%), then connector corrosion at the sensor (15%). Check them in that order before replacing any parts.
tS keeps coming back after a reset — what should I check next? +
A reset only clears the stored tS fault; if it returns, the sensor problem is still present. Move on to the physical checks — test the thermistor, then inspect the harness — since the code will reappear until the root cause is resolved. This is a beginner-friendly job needing only basic hand tools.
How much does it cost to fix Samsung Dryer error tS? +
A DIY repair typically runs $10–$25 in parts, versus $130–$250 for a professional service call, so handling it yourself saves around $120. Expect the work to take about 10–20 minutes.
Which Samsung Dryer models show error tS? +
tS is documented on Samsung electric and gas dryers using an exhaust thermistor for heat regulation, including models such as DVE45R6100C, DVE45T6000W, DV42H5000EW, DVE50BG8300V, and DVG45T3200W. Other units sharing the same control platform can display it too, so the fixes here generally transfer across the series.
