Summary

The service manual for Whirlpool Dryer Model WED6120HW1 provides detailed diagnostic and troubleshooting procedures for technicians. Technicians can initiate Service Diagnostic Mode by pressing any three buttons (excluding POWER) in sequence within 8 seconds. This mode allows access to the diagnostic LED on the main control (ACU), fault codes, and the ability to test components such as the motor, heater, and sensors. The tech sheet emphasizes the importance of checking for loose wires and proper connections before replacing components, as loose connections are a frequent cause of malfunction​.

Common error codes such as F1E1 indicate a failure with the main control (ACU), requiring technicians to verify power at the heater relay and ensure proper connection between the ACU and other components. For temperature-related issues, codes like F3E1 point to a potential problem with the exhaust thermistor, prompting resistance tests to verify if the thermistor is functioning within its normal range. Additionally, other codes guide the technician in inspecting the thermistor’s wiring and connections for shorts or disconnections.

The tech sheet’s maintenance procedures emphasize the importance of maintaining the proper function of critical components, including the heating elements, thermal fuse, and thermistors. Test #4 addresses heating issues by guiding technicians through continuity and resistance checks across the heater relay, thermal cut-off, and high-limit thermostat. Proper airflow is emphasized as a essential factor, and regular inspections of the vent system are recommended to prevent blockages that could hinder dryer performance or cause overheating.
