ELECTRICAL TESTS TIMER
Warning - Always shut off
electrical power to the
washer before beginning
any service repair
procedures.
Grounded Components
When performing service diagnostics, re­
placements and repairs, always check to de­
termine whether all ground wires linking
panel and components are reattached if
removed.
Voltage Checks
Generally, these checks will consist of taking
readings at the wall receptacle to determine
the availability of voltage to the product. Volt­
age checks on individual components of a
product are not recommended due to the
possibility of electrical shock. Component part
testing is best accomplished through conti­
nuity checks with an Appliance Test Meter
{See Electrical Test Equipment).
NOTE: Use of the meter on voltage higher
than the indicated range may cause perma­
nent damage to the meter. To prevent dam­
age, first select the highest range and then
lower the range for readings which fall within
the lower scale.
Set UP meter for use as follows:
1 .
3.
4.
Turn selector knob to desired meter func­
tion and appropriate range.
Plug black lead into socket marked
black {-).
Plug red lead into socket marked red (+).
Place test leads into receptacle to deter­
mine voltage available.
The timer is mounted inside the control con­
sole assembly. The timer shaft protrudes
through the control panel and provides for the
selection of the various machine cycles
available.
The timer is an incremental advance, rotary
type driven by a synchronous motor. The
timer controls and sequences the numerous
steps and functions involved in each machine
cycle. It accomplishes this by providing power
to the various electrical components through
the opening and/or closing action of timer
contacts.
A typical timer and plug connector are illus­
trated in Figure 8-1. The timer has all the con­
necting points brought out to miniature spade
terminals. These terminals are centralized and
aligned on one side of the timer to form a
terminal board.
The connecting wires from the wiring harness
are terminated in a compatible connector
which plugs into the timer terminal board.
Since space is notably limited on the timer
terminal board, terminal identification is pro­
vided by a sticker attached to the side of the
timer. When referring to the sticker for termi­
nal identification, the external timer motor
wires can be used for orientation.
Another source for terminal identification is
the schematic diagram which is supplied with
each washer. The schematic diagram not only
identifies the terminals, but also the plug con­
nector terminals and their respective wire
colors.
