The WW01F01707 is a genuine OEM washer speed sensor for GE and compatible top-load and front-load washers. This sensor detects the rotational speed and position of the drive motor or drum, sending feedback to the control board for precise cycle timing, motor control, and error detection. It features a sealed electronic module, multi-pin connector, and robust housing for durability. Typical lifespan is 7–12 years; failures are most often due to circuit board damage, corrosion, or wiring faults. Symptoms: washer won’t spin or agitate, spin speed errors, erratic drum movement, or error codes. IMPORTANT: Only use OEM sensors for accurate feedback and reliable operation. CRITICAL: Always disconnect power before servicing.
