Maytag Washer Error Code F3E2

F3E2 means the water temperature sensor is sending a signal outside the acceptable range of 14°F to 230°F (-10°C to 110°C). The control board monitors this sensor to regulate water temperature during wash and rinse cycles. When the sensor reading is out of range, the washer flags the fault and may stop or refuse to start certain cycles. The problem typically points to a failed sensor, a wiring issue, or a corroded connector.

It is not recommended to continue running the washer with an active F3E2 error. Without a reliable temperature reading, the control board cannot properly regulate water temperature, which may result in cycles completing incorrectly or not at all. In some cases the washer may prevent operation entirely to protect components. Addressing the fault before continued use is the safest approach.

A power reset may temporarily clear the F3E2 code, but it will return if the underlying problem with the temperature sensor or its wiring has not been corrected. Disconnecting the washer from power for a few minutes and restarting can help confirm whether the fault is intermittent or persistent. A persistent fault after reset indicates a hardware problem that requires diagnosis and repair rather than simply clearing the code.

A knowledgeable DIYer can diagnose and often fix F3E2 by testing the temperature sensor resistance with a multimeter and inspecting the wiring harness. The sensor resistance should read between 500 ohms and 100K ohms. If the wiring is intact and the sensor tests out of range, replacing the temperature sensor is a straightforward repair. If the wiring and sensor both test correctly, the control board may need professional evaluation.

If the repair requires only a new temperature sensor, parts typically range from $15 to $50 depending on the model, making it one of the more affordable washer repairs. If a wiring harness needs replacement the cost may be somewhat higher. A control board replacement, if needed, can range from $100 to $300 or more for parts alone. Labor costs will vary by region if a technician is hired.
