Samsung Dryer Error Code tS — How to Fix (Temperature sensor (thermistor) fault)
Fix Samsung Dryer error tS. Step-by-step guide to diagnose and resolve the temperature sensor (thermistor) fault on Samsung dryers.
What Does Error Code tS Mean?
Error tS on your Samsung Dryer means: The tS code means the dryer’s temperature sensor (thermistor) is reporting a value that’s out of the normal range. When the sensor can’t be trusted, the dryer disables heating to protect the drum and electronics, so clothes stay wet or take a very long time to dry.
What You'll Need
🔧 Tools
- Phillips #2 screwdriver
- T15 Torx screwdriver
- Digital multimeter (with continuity and resistance functions)
- Needle‑nose pliers
- Heat gun or hair dryer (low‑heat setting)
🛒 Parts
- Temperature sensor (thermistor) for Samsung dryer
How to Fix Error tS — Step by Step
- 1
Quick Power Reset
Unplug the dryer or turn off the circuit breaker for at least 60 seconds. Plug it back in and turn the unit on. If the tS code disappears, the issue was a temporary glitch; otherwise continue.
💡 Pro Tip: Leave the dryer unplugged a little longer (2‑3 minutes) if the display is still frozen after the first reset.
- 2
Access the Thermistor Housing
Remove the rear panel: unscrew the four Phillips #2 screws and the two T15 Torx screws that hold the back cover. Slide the panel down and set it aside. The thermistor is a small ceramic disc mounted on the dryer’s heating element housing, usually near the exhaust vent.
💡 Pro Tip: Take a photo of the wiring harness before disconnecting it – it saves guesswork during reassembly.
- 3
Inspect Wiring and Connectors
Locate the two‑wire connector leading to the thermistor. Pull the connector apart and examine the wires for fraying, corrosion, or burnt spots. Use the multimeter on continuity mode; the connector should read near 0 Ω when the pins touch. Any open circuit means the harness is damaged and must be replaced.
💡 Pro Tip: If you see a single broken strand, you can splice with heat‑shrink tubing instead of buying a new harness.
- 4
Test Thermistor Resistance
Set the multimeter to the 20 kΩ range. With the dryer still unplugged, disconnect the thermistor from its connector. Measure resistance at room temperature (about 20 °C). A healthy Samsung dryer thermistor typically reads between 8 kΩ and 12 kΩ. Gently warm the sensor with a hair dryer (do not exceed 120 °C) and watch the resistance drop; it should fall to roughly 1 kΩ‑2 kΩ. If the reading is infinite, erratic, or stays above 15 kΩ when warm, the sensor is faulty.
💡 Pro Tip: Record both cold and hot readings; many service manuals list the exact curve for reference.
- 5
Replace the Faulty Thermistor
Remove the mounting screw (usually a #6 machine screw) holding the thermistor in place. Pull the old sensor out and insert the new one, aligning the screw holes. Re‑attach the wiring connector, making sure it clicks securely. Re‑install the rear panel, tighten all Phillips and Torx screws, and restore power.
💡 Pro Tip: Apply a thin bead of high‑temperature silicone sealant around the sensor if you notice any moisture ingress in the housing.
- 6
Verify the Fix
Run a short drying cycle on the “Air Fluff” or “Sensor Dry” setting. The dryer should progress past the initial heating stage without displaying tS. Use the multimeter again on the live circuit (set to AC voltage) to confirm the heating element receives power when the cycle calls for heat.
💡 Pro Tip: If the dryer still shows tS after a successful sensor replacement, the control board may have stored a fault code; perform another power reset or consider board replacement.
When to Call a Professional
Call a professional if the tS code persists after you’ve replaced the thermistor and verified the wiring, or if you discover burnt traces on the control board. Also, if you are uncomfortable working with high‑voltage components inside the dryer, a qualified technician should handle the repair.
Diagnostic Flowchart
Follow this visual guide to systematically diagnose Error tS:
If your Samsung dryer is displaying the tS error code, you’re likely frustrated with clothes that stay damp or take an eternity to dry. This code indicates a problem with the temperature sensor, also known as the thermistor. Don’t worry; we’ll walk you through understanding the issue, troubleshooting steps, and potential fixes.
What the Samsung Dryer Error tS Actually Means
The tS code signifies that the dryer’s temperature sensor (thermistor) is reporting a value outside the normal operating range. This sensor is crucial for regulating the dryer’s temperature. When it fails or provides inaccurate readings, the dryer disables heating to prevent damage to the drum and electronics. As a result, clothes may not dry properly or take much longer than usual.
The thermistor is usually located near the heating element or in the airflow path. Its resistance changes in response to temperature fluctuations, allowing the dryer’s control board to adjust heat levels accordingly. If the thermistor’s readings become unreliable, the dryer cannot accurately control its temperature.
Diagnose This in 5 Minutes (Before Calling Anyone)
Before diving into complex repairs, perform these quick checks:
- Power cycle: Unplug the dryer or turn off the circuit breaker for at least 5 minutes. This simple reset might clear the error code.
- Check the lint filter: Ensure it’s clean and not clogged. A dirty lint filter can cause issues with airflow and temperature regulation.
- Verify proper installation: Make sure the dryer is installed on a level surface and vented correctly.
Probable Causes, Most Likely First
Here are the common causes of the tS error code, ranked by likelihood:
1. Faulty Thermistor
- Description: The thermistor itself might be damaged or worn out.
- Verification: Use a multimeter to test the thermistor’s resistance (see step 4 in the existing repair steps). Compare the reading to the expected value for your specific dryer model.
- Fix difficulty: Medium
- Cost: $10-$30 (thermistor replacement part)
2. Loose or Corroded Wiring/Connectors
- Description: Corrosion or looseness in the wiring or connectors can disrupt communication between the thermistor and the control board.
- Verification: Inspect the wiring and connectors leading to the thermistor (see step 3 in the existing repair steps). Look for signs of corrosion, damage, or wear.
- Fix difficulty: Easy to Medium
- Cost: $0 (if cleaning/corrosion removal fixes it) to $20 (for replacement parts)
3. Clogged or Blocked Airflow
- Description: Restricted airflow can cause temperature imbalances, leading to thermistor errors.
- Verification: Check the venting system for blockages, kinks, or excessive lint buildup. Ensure proper vent installation and maintenance.
- Fix difficulty: Easy
- Cost: $0 (if cleaning fixes it) to $100 (for vent replacement parts)
4. Control Board Issues
- Description: In rare cases, the control board might be faulty, causing incorrect thermistor readings.
- Verification: This requires advanced diagnostic tools and expertise. If you suspect a control board issue, it’s best to consult a professional.
- Fix difficulty: High
- Cost: $100-$300 (control board replacement part)
