Sensor; Igniter; Temperature Switch - 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.

52. SENSOR

a. While supporting the lower access panel,
remove two screws from bottom edge of lower
access panel, Figure 51.
b. Gently lower the access panel to disengage
guide lugs from bottom edge of front panel.
c. Close gas shut-off valve, Figure 48.
d. Remove wires from sensor terminals,
Figure 52.
e. Set test meter to read OHMS, put meter
probes on sensor terminals. Meter should
read " zero" Ohms. If meter registers an Ohm
reading of any amount, replace sensor.

53. IGNITER

Gas dryers are manufactured with different
igniters. These igniters are tested in the same
way, but have different resitance readings.
a. While supporting the lower access panel,
remove two screws from bottom edge of lower
access panel.
b. Gently lower the access panel to disengage
guide lugs from bottom edge of front panel.
c. Disconnect igniter wires at disconnect block.
d. Set test meter to read Ohms and put meter
probes on terminals of igniter wires.
e. Norton Igniter — meter should read between
45-200 OHMS, Figure 53.
60868 Igniter — meter should read between
75-800 OHMS, Figure 53.
If meter does not read appropriate OHMS,
then replace the igniter.
IMPORTANT: Always examine all wires,
terminals and connectors to be sure wiring is
proper before replacing any components.
NOTE: Test procedures of paragraph 51, 52 and
53 can be performed on workbench if gas valve,
igniter, burner tube and burner housing have
been removed from dryer.

54. TEMPERATURE SWITCH

a. Remove three screws holding the control
assemlby to the control hood rear panel and
cabinet top, Figures 5 and 6.
b. Disconnect wires from temperature switch.
c. Set the meter to read OHMS and apply the
meter probes to the switch terminals.
1. Three Position Heat Switch — Follow the
appropriate wiring diagram for your model
dryer. See SECTION VII of this manual.
2. Infinite Heat Switch — Meter should read
10 Ohms (maximum) with the switch in the
DELICATE setting. Turn switch full
CLOCKWISE direction, meter should
read 10,000 Ohms (minimum).
NOTE: Refer to proper wiring diagram when
reconnecting wires.
