Section 7 Test Procedures
To reduce the risk of electric shock, fire, explosion, serious injury or death:
• Disconnect electric power to the dryer(s) before servicing.
• Close gas shut-off valve to gas dryer(s) before servicing.
• Never start the dryer(s) with any guards/panels removed.
• Whenever ground wires are removed during servicing, these ground wires must be
reconnected to ensure that the dryer is properly grounded.

WARNING
73. TIMER ADVANCE AND
TIMER CONTACT POINTS
(Figure 47)
This test will determine if the timer advances. If the
timer advances then it does not need to be replaced.
a. Advance Test:
For models which produce an audible signal
(a buzzing sound):
(1.) Select a cycle and activate dryer start
switch.
(2.) Rotate timer knob to a position where the
signal will activate, then release timer
knob.
(3.) If timer is advancing, signal will end in less
than 10 minutes.
(4.) If signal continues to sound for more than
10 minutes, replace timer.
For models which do not produce an audible
signal:
(1.) Rotate timer knob to the 10 minute mark.
(2.) If timer is advancing, dryer will cycle into
the cool down period and then to OFF
position.
NOTE: If timer does not advance, see Paragraph 22
for timer replacement.
b. Timer Contact Points:
To check timer contact points proceed as
follows:
(1.) Remove the three screws holding the
control assembly to the control hood rear
panel. See Figure 5.
(2.) Disconnect wires from timer.
NOTE: Refer to wiring diagram when rewiring
timer.
(3.) Set test meter to read Ohms and apply
meter probes to terminals. See Figure 47.
(4.) Starting with timer knob indicator in OFF
position at top of timer, slowly turn timer
knob clockwise until indicator is again
pointing toward OFF position at top of
timer. Meter should register “zero” reading
when circuit being tested is completed by
timer. Refer to Figure 47 for Timer Cycle
Chart showing when circuit is made.
c. Timer Motor Resistance Check
120V motor resistance should be 2,460 – 3,100
Ohms.
240V motor resistance should be 10,900-
13,000 Ohms.
d. Timer Resistor Resistance Check (Electric
Models)
4.7K 10W resistor resistance should be
4,465 – 4,935 Ohms.
