Illustration 40046601 Component Temperature switch 2 1 40097701 Mixing valve 40073801 Timer Results >1 Ω L1-2 L1-1, L1-2, L2-2 L2-1, L2-L1, 1-2 Warm / Cold L1-1, L1-2, 1-2 Cold / Cold L1-1 Measure resistance of terminals on each valve. Resistance across each valve. Approximately 1000 Ω ± 10% Verify input and output voltage is present. See timing sequence chart for functional description of the component. Hot / Cold Warm / Warm L2 L1 Test Procedure Disconnect wires from component to properly measure the resistance of the component. Place switch in the following positions and measure across the terminals below: >1 Ω >1 Ω >1 Ω Verify wiring is correctly connected to the timer. 40055101 Pressure switch 2 1 3 40035001 R0000014 Lid switch− SPST Brake pad kit Do not disconnect the pressure hose from pressure switch to perform measurements. Measure resistance across the following terminals on the pressure switch: Terminal 1 to 2 Terminal 1 to 3 Disconnect wire terminals from switch. Test terminals with switch closed. Test terminals with switch open. If washtub does not stop spinning within seven seconds after opening loading door. If brake pads make noises. 038424W RT3100007 Rev. 1 Rocker switch (Extra Rinse) Measure resistance of switch positions: Closed (ON position) Open (OFF position) 2 Refer to wiring diagram/schematic for correct contacts. Air pressure that actuates switch is determined by the water level of the tub. Continuity (no pressure) Continuity (pressure) Continuity Infinite >1 Ω 1 MΩ Replace all three brake pads. Apply a thin layer of silicone (26594P) on pads, see Service Bulletin “ASQ− 213− B” Continuity Infinite >1 Ω 1 MΩ March 2001 Component Testing Information ! WARNING To avoid risk of electrical shock, personal injury, or death, disconnect power to washer before servicing, unless testing requires it. Illustration 40095003 Component Motor Test Procedure Type of motor: Two speed Results See following section “Internal Motor Diagram and Schematic” for correct wiring contacts. 40040301 Drain pump Verify drain pump is not clogged or damaged. Remove clog and verify proper operation. Replace drain pump if damaged. 40065301 Transmission assembly Type of transmission: 640 rpm Externally identical, must be identified by part number. If transmission locks-up, replace. 40053602 Drive belt Type of drive belt: 640 rpm Refer to “Parts Manual”, to verify which drive belt and pulley size is required. Refer to “Parts Manual” for proper pulley size. 40098701 Power Cord Measure resistance of wires. Continuity should be indicated on each wire. Verify polarity and grounding.
