Summary
The service manual for the Whirlpool Dryer Model WED5620HW2 provides in-depth diagnostic and troubleshooting procedures for appliance technicians. Diagnostic steps start with activating the Service Diagnostic Mode by pressing a specific sequence of any three buttons (excluding POWER and START). This mode allows access to critical information such as fault/error codes and component tests, helping to pinpoint issues within the dryer’s electrical components, including the Appliance Control Unit (ACU) and related systems.
Common error codes like F1E1 indicate problems with the ACU, prompting technicians to perform a series of power checks to verify connections and voltage levels at the board. Additionally, error codes related to heating issues, such as F3E1 (Exhaust Thermistor Open), guide technicians to test the thermistor’s resistance to ensure it operates within the expected parameters. These steps are essential for diagnosing problems in electric dryers, particularly those affecting heating performance and cycle completion.
The manual also outlines essential maintenance procedures for key components like the heating element, moisture sensors, and thermal fuses. For instance, Test #4 covers the heat system, guiding technicians through the process of checking the continuity and resistance of the heater element and associated safety components like the high-limit thermostat and thermal fuse. By following these procedures, technicians can effectively diagnose and resolve issues that may arise during the normal operation of Whirlpool electric dryer.
