Samsung Dryer E1 Error Code: Causes and Fixes
Quick answer: Thermistor value out of range
What you’ll notice
Dryer stops heating or shuts off; thermistor value is outside the expected range.
Samsung
Dryer
Code E1
low severity
Samsung models: The lint filter sits in the door opening on all Samsung DV series dryers. The exhaust duct exits at the lower-rear. Samsung's Vent Sensor actively measures airflow restriction throughout the cycle and directly generates D80/D90 readings when blockage reaches threshold.
Common causes
- Thermistor (temperature sensor) has failed open or short
- Thermistor wiring connector loose
- Thermal fuse blown due to a prior overheating event
Step-by-step fix
- Unplug the dryer.
- Locate the thermistor — usually on the exhaust duct inside the back panel.
- Test resistance with a multimeter: a typical thermistor reads around 10–50 kΩ at room temperature.
- Inspect the thermal fuse (one-shot fuse on the exhaust housing) — it reads 0 Ω if good, open if blown.
- Replace whichever component tests faulty.

Prevention
- Keep the exhaust duct clear.
- Replace the thermal fuse and thermistor together if either has failed — they are inexpensive.
When to stop DIY
If the thermal fuse is blown, also find and fix the root cause (restricted airflow, failed cycling thermostat) before replacing it — it will blow again otherwise.
FAQ
What does E1 mean on Samsung dryer?
E1 usually indicates: Thermistor value out of range.
Can I keep using the appliance with E1?
Use caution. Severity is low. If the thermal fuse is blown, also find and fix the root cause (restricted airflow, failed cycling thermostat) before replacing it — it will blow again otherwise.
How long does this fix usually take?
Typical first-pass troubleshooting takes 30–45 minutes.
