What this codemay mean.
A plain-language reading of the code — always confirm against your model’s documentation.
Mean
A thermistor problem; temperatures are not reading correctly.
The tS code shows a problem with the thermistor, which means temperatures are not reading correctly. Whirlpool lists it for compact heat pump dryers.
Vented models
Not every dryer under this code is a heat pump. If yours is a vented unit, suspect a clogged lint screen first, then the vent that runs outdoors, which may be blocked or restricted. Look it over for kinks and obstructions. Dry time suffers without ample air flow.
