2 Component Testing Information Illustration Component Test Procedure Results Temperature switch Disconnect wires from component to 2 properly measure the resistance of the component. 1 Place switch in the following positions and measure across the terminals below: L1 L2 Hot / Cold Warm / Cold Cold / Cold L12 L11, L12, 12 L11 >1 Ω >1 Ω >1 Ω Mixing valve Measure resistance of terminals on each valve. Resistance across each valve. Approximately 1000 Ω ± 10% Timer Verify input and output voltage is present. ee timing sequence chart for functional description of the component. Verify wiring is correctly connected to the timer Pressure switch 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 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) Lid switch PT Disconnect wire terminals from switch. Test terminals with switch closed. Test terminals with switch open. Continuity >1 Ω Infinite 1 MΩ Brake pad kit If washtub does not stop spinning within seven seconds after opening loading door. If brake pads make noises. Replace all three brake pads. Apply a thin layer of silicone (26594P) on pads, see ervice Bulletin AQ 213 B 2 March 2006
