CHECKING HEAT CONTACTS,
MOTOR CENTRIFUGAL SWITCH
1. Disconnect dryer power source.
2. Gain access to motor and remove
blue and black leads from motor
switch.
3. Use either of the following test
methods using appropriate caution.
A. Live test -- USE CAUTION
1. Using a double insulated spade con-
nector, connect blue and black wires
removed from motor switch.
2. Reconnect dryer to power and set
for heat cycle.
3. Start dryer, if heat is produced,
replace motor switch on motor. If
no heat, continue additional circuit
checks.
B. Continuity Check
(Insulate wires removed from motor
sWitch.)
1. Using clip adapters, attach meter
probes to the blue and black motor
switch terminals.
2. Arrange probe leads away from any
moving parts and set meter on RX1
range.
3. Reconnect dryer to power source
and start dryer, continuity on meter
indicates good switch. No conti-
nuity, replace motor switch or
motor.
4. Open door to stop dryer. When

VOLTAGE CHECKS
For the most part these checks will
consist of taking readings at the wall
receptacle in order to delermine the
availability of voltage to the product.
Voltage checks on individual compo-
nents of a product are not recom-
mended due to the possibility of
electrical shock. Component part
testing is best accomplished through
continuity checks with an Appliance
Test Meter.
Note: Use of the meter on voltage
higher than the indicated range may
cause permanent damage to the meter.
To prevent damage, first select highest
range for readings which fall within the
lower scale.
SET UP METER FOR USE AS FOLLOWS:
1. Turn selector knob to desired meter
function and appropriate range.
2. Plug black lead into socket marked -
(negative).
3. Plug red lead into socket marked
+
(positive).
4. Place test leads into receptacle in
order to determine voltage avail-
able.
