Electrolux Dryer Error Code E71

E71 is a Drying NTC1 alarm indicating that the NTC1 temperature sensor is producing a reading outside the acceptable range. The fault can originate from a wiring failure in the NTC1 harness, a defective NTC1 sensor, or a failed NTC reading circuit on the main control board. The dryer halts the cycle when this code appears to prevent potential overheating.

It is not recommended to continue running the dryer while E71 is active. The code indicates the control board cannot reliably monitor drying temperatures through NTC1, which means the dryer lacks the sensor feedback it needs to prevent overheating. Continued use without a functioning temperature sensor could pose a fire or safety risk.

A reset, such as unplugging the dryer for a few minutes, may temporarily clear the E71 code, but the error will return if the underlying fault is not corrected. If the sensor, wiring, or board circuit is actually defective, the code will reappear once the dryer attempts a new cycle. A reset is useful as a first step to rule out a transient glitch, but it is not a substitute for proper diagnosis and repair.

Some causes of E71 are DIY-friendly, particularly if the fix involves reseating a loose connector or replacing the NTC1 sensor. Start by unplugging the dryer, then inspect the wiring harness connected to NTC1 for obvious damage or loose plugs. If you are comfortable using a multimeter to test thermistor resistance, you can also evaluate the sensor itself before deciding whether a technician is needed for a main board issue.

Repair costs vary widely depending on the root cause. Replacing the NTC1 sensor is typically the least expensive fix, with parts often ranging from $15 to $50 and labor adding $75 to $150 if a technician is needed. A main control board replacement is significantly more costly, with parts alone often falling in the $100 to $300 range, plus labor. Wiring repairs with no parts needed may cost only a service call fee.
