Frigidaire Washer Error Code E74

E74 means the washer detected that the wash water temperature did not increase during a cycle. The control board monitors temperature through a drum water NTC thermistor sensor, and when no rise in temperature is detected, it triggers this code. The fault can stem from a defective thermistor, a failed heating element, or wiring issues in the temperature sensing circuit.

A power reset may temporarily clear the E74 code, but if the underlying component has failed, the code will return once the washer attempts a heated wash cycle. A reset should be used only to confirm the fault is active and repeatable, not as a repair. The root cause must be diagnosed and corrected for the error to stay cleared.

Repair costs vary depending on which component has failed. A replacement NTC thermistor is typically a lower-cost part, while a new heating element or control board will increase the total. Including professional labor, repairs for E74 related faults generally range from around $100 to $350 or more, depending on the part needed and local service rates.

Start by testing the resistance of the drum water NTC thermistor, which should measure approximately 4.8K ohms. If the resistance is out of range, replace the thermistor. If the sensor tests correctly, inspect the wiring harness for damage and test the heating element for continuity. Work through these components in order before considering control board replacement.

Running the washer with an active E74 code means the water is not heating properly, so wash performance will be reduced on cycles requiring warm or hot water. While the washer is unlikely to pose an immediate safety hazard in most cases, continuing to run it without diagnosis could indicate an underlying electrical fault in the heating circuit that warrants attention before extended use.
