Samsung Washer Error Code tE3

The tE3 code on a Samsung washer indicates a fault with the duct condensing temperature sensor. The control board has detected that the sensor circuit is open, short-circuited, or has a connector that is out of place or making poor contact. The washer will stop normal operation until the sensor issue is resolved.

Resetting the washer may temporarily clear the tE3 code, but it will almost certainly return if the underlying sensor or wiring fault has not been corrected. A reset does not repair a broken wire, bad connector, or failed sensor. You should diagnose and fix the root cause before expecting the error to stay clear.

If only the connector needs reseating or cleaning, the repair may cost little to nothing beyond your time. Replacing the duct condensing temperature sensor typically costs between $15 and $60 for the part, plus labor if a technician is hired. A full diagnostic service call from a technician generally runs between $75 and $150 depending on your location.

Some tE3 errors can be resolved without professional help if the cause is simply a loose connector. You can inspect the duct condensing temperature sensor connector for secure seating and visible damage. If the wiring or sensor itself has failed, replacing these components requires basic appliance repair skills and comfort working inside the machine.

It is not recommended to continue running the washer while the tE3 error is active. The duct condensing temperature sensor provides the control board with data needed to manage the condensing cycle safely. Operating without a valid sensor signal could result in improper cycle behavior or potential overheating.
