COMPONENT TEST PROCEDURES
Several components of the machine can be tested before removing or exchanging them.
Some test procedures can be completed without major disassembly other than to
disconnect the component from its circuit; others may be tested from their connector on
the control panel. Often, the only equipment required is a multimeter.
NOISE FILTER
The noise filter is designed to keep DC noise from the motor from filtering into the house
wiring and affecting other appliances, particularly radios and televisions.
Using an ohmmeter, check from the white
connector terminal 1 to the red connector
terminal 3. The resistance should be 0.
Then check from the white connector
terminal 3 to the red connector terminal 1.
The resistance should be 0.
If these tests pass, reconnect the white
connector but not the red connector.
Plug in the machine in.
Read the voltage across terminals 1 and 3
of the red connector. It should be
approximately 120 V
AC
, the same as
