Samsung Dryer Error Code Et

The Et code indicates that the Samsung dryer has detected a fault in the heater thermistor circuit. The thermistor monitors temperature near the heating assembly and communicates with the control board via resistance readings. On gas models, the code can also appear when gas is not being supplied continuously to the burner. The dryer will stop heating until the issue is resolved.

The dryer displays Et and disables heating as a protective measure, so continuing to run the machine with this fault active is not recommended. On a gas model, if you suspect a gas supply issue, confirm there are no gas leaks before troubleshooting further. A faulty thermistor that goes unaddressed could prevent the dryer from properly regulating temperature in future cycles.

A power reset, such as unplugging the dryer for a few minutes, may temporarily clear the Et code, but it will return if the underlying issue is not corrected. If the thermistor is defective, the wiring is damaged, or gas supply is inconsistent, the fault condition will be detected again as soon as the dryer attempts to heat. A reset is useful for confirming whether the fault is intermittent, but it is not a fix.

Some causes of the Et error are DIY-friendly. Checking that the gas supply valve is fully open on a gas model costs nothing and takes only a moment. Inspecting and reseating the thermistor wiring connector is also straightforward for someone comfortable working inside an appliance. Replacing the thermistor itself is a moderate repair, but if the control board is at fault, that replacement is more complex and may be better handled by a technician.

If only the heater thermistor needs replacement, parts typically range from $10 to $40 depending on the model, and a technician's labor for this repair generally falls in the $80 to $150 range. If the control board is the root cause, board replacement parts and labor can run $150 to $350 or more. Getting the wiring and thermistor diagnosed first can help avoid unnecessary parts costs.
