Door Switch; Signal Control; Timer Contact Points - Amana LG4219*2 Service Manual

a W A R N I N G
To reduce the risk of electric shock, fire, explosion, serious injury or death:
•Disconnect electric power to the dryer before servicing.
•Close gas shut-off valve to gas dryer before servicing.
•Never start the dryer 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.

55. DOOR SWITCH

a. While supporting the lower access panel,
remove two screws from bottom edge of lower
access panel, Figure 22.
b. Gently lower the access panel to disengage
guide lugs from bottom edge of front panel.
c. Disconnect wires from door switch, Figure 21.
NOTE: Refer to appropriate wiring diagram when
rewiring switch.
d. Set meter to read Ohms and apply meter
probes on switch terminals 1 and 3 with door
closed. You should get " zero" reading.
e. Apply probes to terminals 1 and 2 with door
closed. The meter should read " no reading" .
f. Open door. Meter should read " zero" .

56. SIGNAL CONTROL

a. Remove the three screws holding the control
assembly to the control hood rear panel,
Figures 5, 6 and 8.
b. Disconnect wires from signal control.
c. Set meter to read Ohms and apply meter
probes to terminals of signal control. Meter
should read approximately 1,000 Ohms at all
times.
57. TIMER ADVANCE and TIMER CONTACT
POINTS (Figure 54)
This test will determine if the timer advances. If the
timer advances then it does not need to be
replaced.
Advance Test:
For models which produce an audible signal
(a buzzing sound):
1. Select a cycle and activate dryer start switch.
RS3200001 (502992R3)
Rev. 3
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
9 for timer replacement.
To check timer contact points proceed as follows:
a. Remove the three screws holding the control
assembly to the control hood rear panel,
Figures 5, 6 and 8.
b. Disconnect wires from timer.
NOTE: Refer to appropriate wiring diagram when
rewiring timer.
c. Set test meter to read OHMS and apply meter
probes to terminals, Figure 54.
d. 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 54 for Timer Cycle Chart showing
when circuit is made.
Timer Motor Resistance Check
120V 60 Hz. motor resistance 2,460 - 3,100 Ohms.
