The WG04F11798 is a genuine OEM dryer outlet thermistor for GE and compatible dryers. This sensor monitors the temperature of exhaust air leaving the dryer drum, sending feedback to the control board to regulate heat and prevent overheating. It features a precision thermistor element in a heat-resistant housing with a plug-in connector for easy replacement. Typical lifespan is 7–12 years; failures are most often due to thermal fatigue, corrosion, or electrical faults. Symptoms: dryer not heating correctly, error codes (e.g., tE, F3), overheating, or long dry times. IMPORTANT: Only use OEM thermistors for accurate temperature control and safety. CRITICAL: Always disconnect power before servicing.
