Quiz
1. Drive motor is inoperative, you need to check
winding resistance. Where do you go?
a) Pull the washer out, remove the back
cover, disconnect terminal block, and take
resistance reading.
b) Remove top cover, trace motor winding to
timer, and check resistance values.
c) Remove lower front cover and read wind-
ings resistance value at the back of the
plug, left-side terminals, front view. RED,
BLUE, and BLACK leads. From one lead to
the other should read 2.6 ohm +/- 7%.
2. The new timer version controls the program-
ming operation of the washer.
T or F
3. How does the dispenser drawer operate?
a) As the timer advances to the appropriate
function, it will mechanically activate a
lever to open the proper chamber.
b) It is timer-cam operated to distribute the
fabric softener and bleach at the selected
settings.
c) The detergent portion automatically mixes
with the initial water draw. Thereafter,
fabric softener/bleach solenoids are ener-
gized at the appropriate program advance
mode.
4. What controls drive motor speeds?
a)
Electronic board reads tachogenerator
and sets up different speeds depending on
“code function” (e.g., wash or spin mode).
b)
Timer energizes the different resistance
windings for slow and fast speeds as told
to by control board.
c) None of the above. Timer totally controls
the speeds according to customer’s speed
selection.
5. When fuse is blown on electronic board:
a) If timer is manually advanced, the drain
motor and some other components can be
energized.
b) The entire unit is totally dead.
c) Only the timer motor advances.
6. The new wax motor (switch lock circuit) is
energized:
a) Any time unit is in operation.
b) Only during the wash cycle.
c) Only during the spin/drain cycle.
7. To replace the drive motor, you must:
a) Remove power, remove lower front panel,
disconnect motor plug harness, and re-
move motor mounting screws.
b) Remove power, pull unit, remove back
cover, remove belt, remove motor plug
connector, remove motor mounting screws.
8. Unit is totally dead, door lock light glows, door
is closed. You do the following:
a)
Check the fuse on the electronic board.
b)
Check the harness to the lock switch. If
O.K., replace lock switch assembly.
c)
Check reed switch for continuity.
d)
None of the above. Replace timer.
9. Unit is totally dead, door lock light does not
glow. Your check points are:
a) No input from timer. Replace timer.
b) Fuse on electronic board blown. Lock
circuit not receiving signal.
c) Voltage at outlet. If O.K., remove power
and check reed switch circuit.
d) Reed switch circuit not connected properly
to valve bypass. Check connector at board;
if O.K., replace board.
10. Timer not advancing. Your check points are:
a) Valve bypass not responding. Check 6- and
10-pin connectors. If O.K., replace board.
b) Timer motor windings (first remove power).
Check for 6C to 6T continuity reliability. If
all O.K., replace PC board. If not, replace
timer.
c) Bypass switch inoperative, neutral line
contaminated. Replace PC board.
