Samsung Dryer Error Code Et — Overheating
What this means
The Et error is a safety shutdown triggered when the dryer's internal temperature exceeds safe limits. This is almost always caused by restricted airflow from a clogged exhaust vent or lint buildup. It's a fire safety concern and should be addressed immediately.
Alternate codes: E3
Step-by-step fix
4 stepsStop using the dryer immediately
Do not restart the dryer until the airflow issue is resolved. Overheating is a fire risk.
If you smell burning, unplug the dryer immediately and check for smoldering lint.
Clean the entire exhaust vent
Disconnect the exhaust duct from the back of the dryer and from the wall. Use a vent brush kit to clean the entire length of the duct. Vacuum out any lint from both ends and from inside the dryer where the duct connects.
A dryer vent brush kit with flexible rods can clean vents up to 20+ feet long.
Check the lint trap housing
Remove the lint filter and use a vacuum with a narrow attachment to clean inside the lint trap housing. Lint can accumulate deep inside where the filter doesn't reach.
Fabric softener residue can coat the lint screen and restrict airflow even when it looks clean. Wash the screen with soap and water monthly.
Verify airflow at the exterior vent
Go outside and check the vent hood while the dryer is running. You should feel strong, warm airflow. If the flap doesn't open or airflow is weak, the vent is still blocked.
Bird nests and pest nests in exterior vents are more common than you'd think.
When to call a professional
If you've cleaned everything and the dryer still overheats, the thermal fuse or heating element may be stuck on. This requires professional diagnosis.
