Samsung Dryer Error tC: Temperature Sensor Error

Clear meaning, realistic next steps, and safe guidance without turning the page into a long repair manual.

What it means

The dryer has detected a fault in its temperature measurement system. One or more temperature sensors are reporting values outside expected parameters, preventing safe heat regulation.

Severity

Medium - some user checks may help, but repeated faults often need service.

Can you fix it yourself?

Partial — start with DIY steps

Most likely cause

Lint screen blocked — reduced airflow causes temperature to spike or fluctuate, triggering the sensor fault

Also displayed as tS, t5, tC, tO, t0, tE, tE3, tC5, tCS, 1 tC, 1tC5, 1tCS on some models.

Estimated time for safe first checks: 10–15 min for lint clean; Professional if sensor fails.

Step-by-Step DIY Fix Guide

  1. SAFETY: Unplug the dryer.
  2. Remove and clean the lint screen thoroughly — hold it up to light and confirm you can see through the mesh. Rinse under water if clogged.
  3. Check the exhaust vent: disconnect the duct from the back of the dryer and verify there is no lint blockage in the first 12 inches of duct.
  4. Check the exterior vent cap — confirm the flap opens freely and no bird's nest or debris is blocking it.
  5. Reinstall the lint screen, reconnect the duct, and restore power.
  6. Run a timed dry cycle (not sensor dry) at a medium heat setting.
  7. If tC returns after cleaning the lint system, the temperature sensor needs professional replacement.

If the warning comes back after restart

  • If the door closes normally but the warning keeps returning, the latch or switch path becomes more likely than a simple alignment issue.
  • If airflow still seems weak after the basic checks, the fan path or a deeper obstruction becomes more likely.
  • If the warning returns immediately after a clean restart, the sensor or wiring path becomes more likely than a one-time glitch.

What This Error Means

Error tC on your Samsung dryer means: The dryer has detected a fault in its temperature measurement system. One or more temperature sensors are reporting values outside expected parameters, preventing safe heat regulation. Also displayed as tS, t5, tO, t0 on some models. The dryer's self-diagnostic system has flagged this condition and may have paused the current cycle.

The most frequent cause is lint screen blocked — reduced airflow causes temperature to spike or fluctuate, triggering the sensor fault. Work through the causes and steps below before calling a technician.

Many cases of tC can be partially resolved by the homeowner. Complete all DIY steps before contacting a technician.

The lint screen and exhaust vent work together to maintain safe operating temperature. A clean lint screen alone is not enough if the duct is clogged — hot air must be able to exit freely from drum to outside for the dryer to operate safely and efficiently.

Most Likely Cause by Symptom

The Samsung dryer may stop, pause, or refuse to complete the cycle normally.

Likely cause: Lint screen blocked — reduced airflow causes temperature to spike or fluctuate, triggering the sensor fault

Check first: SAFETY: Unplug the dryer.

Performance may drop because airflow, filtering, or draining is restricted.

Likely cause: Exhaust vent system clogged with lint — same effect as a blocked lint screen but further downstream

Check first: Remove and clean the lint screen thoroughly — hold it up to light and confirm you can see through the mesh. Rinse under water if clogged.

The warning may return immediately because the appliance is detecting an internal fault.

Likely cause: Failed NTC temperature sensor

Check first: Check the exhaust vent: disconnect the duct from the back of the dryer and verify there is no lint blockage in the first 12 inches of duct.

Common Causes

  • Lint screen blocked — reduced airflow causes temperature to spike or fluctuate, triggering the sensor fault
  • Exhaust vent system clogged with lint — same effect as a blocked lint screen but further downstream
  • Failed NTC temperature sensor
  • Wiring fault between temperature sensor and control board

What Not to Do

  • Do not run the dryer without the lint screen in place — unfiltered lint can clog the sensor and heating elements

Model and Display Variation Notes

Model-family notes

  • Samsung dryer display wording and code formats can vary by series.
  • If your model behaves differently, check the owner manual before trying any deeper maintenance step.
  • Some models may display the same fault as tS, t5, tC, tO, t0, tE, tE3, tC5, tCS, 1 tC, 1tC5, 1tCS.

Display and panel differences

  • Some control panels show this issue as tS, t5, tC, tO, t0, tE, tE3, tC5, tCS, 1 tC, 1tC5, 1tCS instead of only tC.
  • Panel wording and whether the code appears with letters, numbers, or a longer variant can differ by model family.

Parts, Tools and Service Options

Common parts

  • NTC temperature sensor ($15–$40)
  • Thermal fuse if fuse has blown from overheating ($10–$25)
  • Wiring harness section if wiring is damaged ($20–$50)

Manual and model check

Check your exact model and manual before ordering any Samsung dryer parts.

Service option

Samsung service visit if the warning returns after the basic checks are complete.

When Not to Keep Troubleshooting

tC persists after cleaning lint screen and confirming vent is clear

  • Dryer runs but produces no heat even without tC displayed

How to Prevent It Recurring

  • Clean the lint screen after every single cycle — a blocked screen is the leading cause of temperature sensor errors on Samsung dryers
  • Have the exhaust vent professionally cleaned annually if the dryer is used daily
