FOR SERVICE TECHNICIAN'S USE ONLY
TEST #2: Motor Circuit
This test will check the wiring to the motor
and the motor itself.
1. Unplug dryer or disconnect power.
2. Check for loose, worn, or damaged drum
belt—repair as necessary.
3. Door Switch problems can be uncovered
by following procedure under TEST #5: Door
Switch, page 17.
4. Check the wiring and components in the
motor circuit by referring to the appropriate
wiring diagram on pages 19–20.
Check the thermal fuse. See TEST #3a:
Thermal Fuse, page 17.
Continue with step 5 below to test the
remaining components in the motor circuit.
5. Check the drive motor. Slowly remove the
drum belt.
6. Remove the white connector from the drive
motor switch.
7. Remove the bare copper wire terminal from
pin 5 of black drive motor switch.
8. Using the appropriate wiring diagram on
pages 19–20, check for the resistance values
of the motor's Main and Start winding coils
as shown in the following table.
NOTE: Main and Start winding coils must be
checked at the motor.
Resistance
Winding
in ohms
MAIN 2.4–3.6
START 2.4–3.8
 If the resistance at the motor is correct,
there is an open circuit between the motor
and the timer. Check and repair the main
wiring harness.
 If the Main or Start winding resistance is
much greater or less than the values listed
in the table above, replace the motor.
9. Reassemble all parts and panels.
10. Plug in dryer or reconnect power.

TEST #3: Heat System
This test is performed when either of the
following situations occurs:
3 Dryer does not heat
3 Heat will not shut off
This test checks the components making up
the heating circuit.
Dryer does not heat:
1. Unplug dryer or disconnect power.
2. Remove rear panel to access thermal
components.
3. Using an ohmmeter and referring to the
wiring diagram, measure the resistance from
timer terminal A to the terminal at the heater
(red/white).
 If the resistance is about 10 Ω (120V
models) or about 18 Ω (240V models),
go to step 5.
 If an open circuit is detected, go to step 4.
4. Visually check the wire connections to the
operating thermostat, high limit thermostat, and
heater. If the connections look good, check for
continuity across each of these components.
 Replace the heater if it is electrically open.
 Replace the high limit thermostat if it is
electrically open.
 Replace the operating thermostat if it is
electrically open.
5. If the preceding steps did not correct the
problem and L1 and L2 were both detected,
replace the timer.
6. Reassemble all parts and panels.
7. Plug in dryer or reconnect power.
