Slowly remove drum belt.
5. Remove the white connector from the
drive motor switch. See Figure 7.
6. Using Figure 8, 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.

If the resistance at the motor is correct,
there is an open circuit between the
motor and machine control electronics.
Check for failed belt switch.
If the Start winding resistance is much
greater than 4 ohms, replace the mo-
tor.
7. Check the belt switch by measuring re-
sistance between the two blue wires, as
shown in Figure 9, while pushing up the
belt switch pulley.

Checking the belt switch.
If the resistance reading goes from in-
finity to a few ohms as pulley arm clos-
es the switch, belt switch is OK. If not,
replace the belt switch.
If belt switch is OK and there is still an
open circuit, check and repair the wir-
ing harness.
8. Door switch problems can be uncovered
in the Door Switch Diagnostic Test; how-
ever, if this was not done, the following
can be done without applying power to
the dryer. Connect an ohmmeter across
P8-3 (neutral, white wire) and P8-4 (door,
tan wire).
