Frigidaire Dryer Error Code E71

E71 indicates an NTC thermistor circuit failure, specifically an open circuit condition in the temperature sensor loop. The NTC thermistor monitors drum air temperature, and when the control board cannot read a valid signal from it, the dryer stops and displays E71. The fault can originate from the sensor itself, the wiring harness, or the main control board.

No. The E71 code typically prevents the dryer from operating normally because the control board cannot monitor drum temperature. Running the dryer without a functioning temperature sensor creates a risk of uncontrolled overheating. The dryer should remain off until the fault is diagnosed and corrected.

A reset may temporarily clear the E71 code, but if the underlying fault in the NTC circuit has not been corrected, the error will return once the dryer attempts to run. Resetting is not a repair. The thermistor, wiring harness, and control board connections need to be inspected and tested to permanently resolve the fault.

Many E71 repairs are within reach of a confident DIYer. Start by testing the NTC thermistor resistance with a multimeter. At room temperature (25°C) it should read approximately 50K ohms. If the sensor is good, check and reseat the faston connectors on the NTC harness and the edge connector at J4 on the control board. If all wiring checks out, the control board will need replacement, which is a more involved repair.

Costs vary depending on what component has failed. Replacing the NTC thermistor is typically the least expensive fix, with parts generally ranging from $15 to $40. If the electronic control board needs replacement, parts alone can range from $80 to $200 or more depending on the model, with professional labor adding to that total.
