Results
Also check between each terminal and capacitor case .......................... Type of motor: Three speed
Verify drain pump is not clogged or damaged.
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 See following section “Internal Motor Diagram and Schematic” for correct wiring contacts.
Remove clog and verify proper operation. Replace drain pump if damaged.
