Dryer Test Procedures
IMPORTANT: Electrical test procedures in this
service manual are performed by using a Volt-Ohm
meter. Tests can also be performed using a multi-
meter or any other electrical testing equipment with
which the service person is familiar.
37. Timer Contacts
Refer to Figure 10 .
a. Disconnect wires from timer, except timer
motor wires.
NOTE: Refer to appropriate wiring diagram when
rewiring timer.
b. Manually rotate timer out of “OFF” position
and into cycle.
c. Set test meter to read Ohms. The following
readings should be found:
(1) Motor circuit test – L1 and M = “zero”
Ohms (closed)
(2) Heat circuit test – L2 and H = “zero” Ohms
(closed)
(3) Timer motor test – T and N =
approximately 2460-3100 Ohms or apply
live power to timer motor terminals and
motor should run.
NOTE: Timer Motor Resistance:
120 Volt, 60 Hz 2,460 – 3,100 Ohms
(4) Rotate timer to “cooldown” (5 minutes
before “OFF”). “Infinite” (open) reading
should be found between L1 and H.
(5) Rotate timer to “OFF” position. “Infinite”
(open) reading should be found between L1
and M and between L1 and H.
NOTE: Timer motor power is supplied through M
terminal.
38. Fabric Selector Switch
NOTE: Refer to proper model wiring diagram
when rewiring switch.
a. Set test meter to read Ohms and apply meter
probes to switch terminals.
NOTE: Refer to proper model wiring diagram
when reconnecting wires.
To reduce the risk of electric shock, fire, explosion, serious injury or death:
• Disconnect all electric power to the machine and accessories before servicing.
• Close gas shut-off valve to gas dryer before servicing.
• Never start machine with any guards/panels removed.
• Whenever ground wires are removed during servicing, these ground wires must be
reconnected to ensure that the machine is properly grounded.
• Washer motor not grounded! Disconnect electric power before servicing motor.
