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

Air pressure that actuates switch is determined by the water level of the tub. Continuity (no pressure) Continuity (pressure)

Disconnect wire terminals from switch. Test terminals with switch closed. Test terminals with switch open.

Results

Continuity Infinite

If washtub does not stop spinning within seven seconds after opening loading door.

Replace all three brake pads.

>1 Ω 1 MΩ

If brake pads make noises.

Apply a thin layer of silicone (26594P) on pads, see Service Bulletin “ASQ−213−B” See following section “Internal Motor Diagram and Schematic” for correct wiring contacts.

Motor

Type of motor: Two speed

40084501

Capacitor

Discharge Capacitors Remove wires from capacitor terminals and connect ohmmeter, set on highest resistance scale to terminals.

Between Terminals: Meter should momentarily deflect towards zero then return to over 5 MΩ. If no deflection occurs, or if continuous deflection occurs, replace capacitor. Terminal to Case: Infinite resistance

40040301

Drain pump

Also check between each terminal and capacitor case. 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
