Schematic illustration of a typical dryer — not your exact model.

Before you start — unplug the dryer, and on a gas model shut off the gas supply. Let it cool first — the drum, heater and exhaust can be hot. If a step involves the heating element, wiring, or opening the cabinet and you're unsure, stop and call a qualified technician.

Step-by-step fix

1Clean lint screen and ventClear the filter and exhaust duct so heat can escape.
2Power cycleUnplug the dryer for a minute, then restore power and retry.
3Watch the runIf it starts and heats normally, the code was heat-related and should stay clear.
4Service the sensorIf tS persists, have the thermistor and its wiring tested and replaced.

Still showing tS?

If you’ve worked through every step and tS keeps returning, an internal part likely needs testing and replacement. That’s a job for a qualified appliance technician, who can measure the suspect part against the service-manual spec before replacing it.
