Understanding the Problem
The HS L error on many dryers is a heating-safety or temperature sensor related fault. It usually appears when the dryer detects an abnormal temperature condition (overheat or failed temperature sensing) or when a safety device has tripped to prevent a fire. When the control board receives a signal that temperature is out of expected range or the sensor circuit is open/shorted, it will display an HS-style code to indicate the heating-sensor/heat-safety fault. This problem commonly causes the dryer to run but not heat, to stop mid-cycle, or to run extended cycles with long drying times. Root causes include a failed thermistor/temperature sensor, a blown thermal fuse or high-limit thermostat, a faulty heating element causing irregular temperature, blocked venting that triggers overheating, or wiring/control-board faults. Proper diagnosis requires checking error history, running diagnostics (if the model supports it), and testing components with a multimeter before replacing parts.
Common Symptoms
HS L shows on the display; dryer runs but won’t heat or cuts out; very long drying times; dryer may stop mid-cycle; or dryer may run then trip and show the code again.
Common Causes
- Failed thermistor / temperature sensor (open or out-of-range)
- Blown thermal fuse or tripped high-limit thermostat (safety cut-out)
- Restricted venting/airflow causing overheating or faulty control board/wiring

Helpful Repair Tip
Start by unplugging the dryer, disconnecting the vent and running a manual diagnostic or self-test (consult your model manual). Then check continuity of the thermal fuse and temperature sensor with a multimeter — an open thermal fuse or a sensor out of spec is the most common confirmed cause.
Frequently Asked Questions
How can I tell if the temperature sensor or the thermal fuse is bad?
Unplug the dryer and access the sensor and thermal fuse per your model’s service manual. Use a multimeter set to continuity/ohms: a thermal fuse should show continuity (near 0 ohms) if good; a completely open reading means it’s blown. A thermistor’s resistance should change with temperature — you can compare its cold resistance to the specification in the manual. If the sensor reads open or a value well outside spec, it should be replaced.
Is it safe to keep using the dryer when it shows HS L?
No. HS L indicates a heating or safety-related issue. Continuing to use the dryer risks overheating and potential fire hazard. Stop using the appliance, clear lint and vents, and perform the diagnostic checks or call a technician before running it again.
