Summary
The service manual for the Whirlpool dryer WED9600TZ0 provides a detailed diagnostic guide and troubleshooting procedures for technicians. Key diagnostic steps include entering the diagnostic test mode by pressing a sequence of buttons. Once in diagnostic mode, the dryer will display active and saved fault codes, which guide the technician in identifying faulty components like the motor, heater, or control board. Technicians can use this mode to perform checks on essential parts, such as the door switch, moisture sensor, and thermistors, ensuring the dryer’s critical systems function properly.
Common error codes include F01, which indicates a primary control failure requiring the replacement of the machine control electronics, and F20, which signals a heater failure, necessitating checks on the heater relay and connections. For issues with the thermistor, such as F22 (outlet thermistor open) or F23 (outlet thermistor shorted), the tech sheet advises checking the thermistor’s resistance to verify whether it is within the correct range.
Regular maintenance procedures are also outlined, emphasizing keeping the vent system clear of obstructions to prevent airflow issues, which can cause the dryer to overheat or operate inefficiently. Technicians are encouraged to check the continuity of key components like the thermal fuse, inlet thermistor, and heating element, as well as inspect for wear on mechanical parts such as the belt and drum rollers, ensuring safe and efficient dryer operation.
