Washer-dryer combo displays E14 and may not heat properly during wash or dry; temperature readings seem incorrect.

Safety first: Unplug the appliance before accessing internal components.

• Locate NTC sensor: For wash temperature, the NTC is usually mounted in the tub or heater housing. For dry temperature, it is mounted in the air duct or near the heater.
• Inspect wiring: Check the sensor connector and wiring harness for loose connections or damage.
• Check mounting: Ensure the sensor is properly seated in its bracket or well and making good thermal contact.
• Technical testing: A technician can measure the sensor resistance at room temperature and compare it to RCA specifications. An open or shorted reading indicates a bad sensor.
• When to replace parts: Replace the NTC temperature sensor if it is out of specification or physically damaged. If a new sensor does not clear E14, the main control board may be defective.
