Answer to continue safely
Is it safe to keep using?
No. Without a functioning temperature sensor, the dryer cannot regulate heat. Running the dryer risks overheating clothes and creating a fire hazard. Use only the air-dry (no heat) setting until the sensor is replaced.
Can I reset the code?
Yes. A power cycle may temporarily clear the tS code if caused by a glitch. However, a failed thermistor will trigger the code again. Sensor replacement is required for a permanent fix.
When to stop immediately?
Stop if you notice: The dryer produces excessive heat — clothes or the drum are very hot to the touch, You smell burning from inside the dryer.
Symptoms You May Notice
Dryer shuts off shortly after starting
The dryer begins a cycle but stops within a few minutes because the control board cannot verify a safe operating temperature.
tS or tO code on display
The control panel shows the temperature sensor error code, preventing heated drying cycles.
Clothes take much longer to dry
Before the code appears persistently, drying cycles may become progressively longer as the sensor intermittently misreads temperature.
Dryer overheats before shutting down
A shorted sensor (tO variant) may under-report temperature, allowing the dryer to overheat before the backup thermal fuse activates.
Possible Causes
Open-circuit thermistor
The thermistor's internal resistance element breaks from thermal fatigue, creating an open circuit that reads as infinite resistance to the control board.
Requires ProfessionalLoose or corroded wiring connection
The connector between the thermistor and the main board can develop corrosion or work loose from vibration, causing intermittent or complete signal loss.
Requires ProfessionalShorted thermistor
Less common than an open circuit, a short in the thermistor causes it to report near-zero resistance, which the control board interprets as an extremely high temperature reading.
Requires ProfessionalSafe Checks You Can Do
-
1
Power cycle the dryer
Unplug the dryer for 5 minutes to reset the control board. Plug it back in and attempt a timed dry cycle. If tS was a one-time sensor glitch, it may not return.
If tS clears but returns after 15-20 minutes of running, the sensor is failing intermittently and needs replacement soon.

2
Check the vent system
Disconnect the vent hose and inspect for lint blockage. A clogged vent causes overheating that accelerates thermistor degradation.
Run the dryer briefly with the vent disconnected (outdoors or in a well-ventilated area) — if tS does not appear, the vent restriction may be contributing to sensor failure.
When to Call a Professional
Contact a qualified technician if:
- tS code returns after every power cycle reset within minutes of starting
- The dryer alternates between no heat and excessive heat on successive runs
- The thermal fuse has also blown, indicating the sensor failure caused an overheating event
