DIAGNOSTIC GUIDE
Before servicing, check the following:
Make sure there is power at the wall outlet.
Has a household fuse blown or circuit breaker tripped? Time delay
fuse?
Is dryer vent properly installed and clear of lint or obstructions?
All tests/checks should be made with a VOM
(volt-ohm-milliammeter) or DVM (digital-voltmeter) having a
sensitivity of 20,000 ohms per volt DC or greater.
Check all connections before replacing components. Look for
broken or loose wires, failed terminals, or wires not pressed into
connectors far enough.
A potential cause of a control not functioning is corrosion on
connections. Observe connections and check for continuity with an
ohmmeter.
Connectors: Look at top of connector. Check for broken or loose
wires. Check for wires not pressed into connector far enough to
engage metal barbs.
Resistance checks must be made with dryer unplugged or power
disconnected.

Overview

This document outlines the diagnostic and troubleshooting procedures for a dryer, focusing on its electronic controls, motor, heating system, and various sensors. It also provides instructions for accessing and reinstalling electronic assemblies and other components.

Function Description

The dryer is designed to dry clothes efficiently, incorporating various cycles and options to suit different fabric types and drying needs. Its operation is managed by machine control electronics, which monitor and regulate key components like the motor, heater, and sensors to ensure proper and safe functioning. The user interacts with the dryer through a console that includes buttons, a cycle selector knob, and a two-digit display for estimated time remaining and fault codes.

Usage Features

The dryer offers several features to enhance its usability and performance:

  • Diagnostic Test Mode: This mode allows service personnel to test and verify all inputs to the machine control electronics. It can be activated by selecting any button (except Pause/Cancel) and following a specific press/hold sequence. Upon successful entry, all console indicators illuminate for 5 seconds, and "88" appears in the display.
    • Unsuccessful Entry: If entry fails, pressing Pause/Cancel twice, then Power, can help. If indicators come on, a different button can be tried. If no indicators come on, further troubleshooting is required.
    • Saved Fault Codes: The dryer stores fault codes, which are displayed alternately as "F-" and "XX" (where XX is the fault code). Pressing the same button used to activate diagnostics will cycle through the most recent fault codes, accompanied by a beep tone.
    • Console Buttons and Indicators Diagnostic: In diagnostic mode, pressing console buttons or rotating the cycle selector will produce a beep and toggle corresponding indicators. Pressing "Time Adjust +" (more time) toggles the left digit of the display, while "Time Adjust -" (less time) toggles the right digit.
    • Door Switch Diagnostic: Opening the door in diagnostic mode should trigger a beep and display an alphanumeric number. Closing it should result in a beep and "88" being displayed.
    • Moisture Sensor Diagnostic: With the door open, bridging the two metal sensor strips inside the dryer with a wet cloth or finger should produce a continuous beep and display an alphanumeric number if the sensor is functioning correctly.
    • Motor, Heater, and Console ID Diagnostic: Closing the door and pressing Start should activate the motor and heater, and the display will show a console ID (C0-C9).
    • Displaying Inlet Air Flow: After fault codes are displayed, pressing the Wrinkle Shield button activates airflow detection. A countdown timer starts (30 or 50 seconds), and the dryer turns on. A Dryness modifier LED indicates the airflow range (More, Normal, Less) corresponding to the displayed number.
    • Displaying Line Voltage: After fault codes, pressing the Cycle Signal button displays the line voltage. A Dryness modifier LED indicates the voltage range (More, Normal, Less).
  • Manual Load Test: This test can be activated similarly to the diagnostic mode. After "88" flashes, the motor starts, and the Heavy Duty LED flashes, initiating the Manual Load sequence. This allows for testing the motor and heater elements independently.
  • Customer-Focused Drying Modes: The dryer allows adjustment of automatic drying cycles to address issues like clothes being damp or over-dry. By pressing and holding the Dryness button for 5 seconds, the current drying mode (default "1") is displayed. Subsequent presses allow selection of different drying modes ("2" for 15% more drying time, "3" for 20% more drying time). The selected mode is saved by pressing the Start button.
  • Display Fault Codes: The dryer indicates specific fault codes (e.g., PF for Power Failure, AF for Restricted Airflow, F-01 for Primary Control Failure, F-02 for Keypad/User Interface Failure, F-22/F-23 for Exhaust Thermistor issues, F-24/F-25 for Inlet Thermistor issues, F-26 for Motor Drive System Failure, F-28/F-29 for Moisture Sensor issues, F-30 for Restricted Airflow) to help diagnose problems.
