Test Procedures
WARNING
To reduce the risk of electric shock, fire, explosion,
serious injury or death:
• Disconnect electric power to the dryer before
servicing.
• Close gas shut-of valve to gas dryer before serv-
icing.
• Never start the Dryer with any guards/panels re-
moved.
• Whenever ground wires are removed during serv-
icing, these ground wires must be reconnected to
ensure that the dryer is properly grounded.
W001R1
IMPORTANT: Electrical test procedures in this service
manual are performed by using a Volt-Ohm meter.
Tests can also be performed using a multimeter or any
other electrical testing equipment with which the serv-
ice person is familiar.
Timer Contacts
.
1. Disconnect wires from timer, except timer motor wires.
NOTE: Refer to wiring diagram when rewiring timer.
2. While supporting timer, remove screws holding timer to con-
trol cabinet.
3. Pull timer out through control panel opening as far as wires
will permit.
4. Manually rotate timer out of “OFF” position and into cycle.
5. Set test meter to read Ohms. The following readings should
be found:
a. Motor circuit test – L1 and M = “zero” Ohms (closed)
b. Heat circuit test – L2 and H = “zero” Ohms (closed)
c. Timer motor test – T and M (1702 and1709 suffix models)
or T and N (all other models) = approximately 2460-3100
Ohms or apply live power to timer motor terminals and
motor should run.

Timer Motor Resistance:
120 Volt, 60 Hz
2,460 – 3,100 Ohms
240 Volt
10,900 – 13,000 Ohms
24 Volt
80 – 130 Ohms
d. Rotate timer to “cooldown” (5 minutes before “OFF”).
“Infinite” (open) reading should be found between L2 and
H.
e. Rotate timer to “OFF” position. “Infinite” (open) reading
should be found between L1 and M and between L2 and
H.
NOTE: Timer motor power is supplied through M (1702
and 1709 models) or N (all other models) terminal.
Drive Motor
.
1. Remove motor and exhaust assembly.
2. Disconnect motor wire harness at motor disconnect block.
NOTE: Refer to
Internal Wiring of Dryer Motor Switch
for wiring schematic.
