Remove the white connector from the drive motor
switch. See figure 6.
7.
Remove the bare copper wire terminal from pin 5
of black drive motor switch. See figure 7.
8.
Using figure 7, 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 3
Ω
, replace the motor.
9.
Check the belt switch by measuring resistance
between the two blue wires as shown in figure 8,
while pushing up the belt switch tension pulley.
➔
If the resistance reading goes from infinity to a
few ohms as pulley arm closes 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 wiring harness.
10.
Door switch problems can be uncovered by
following procedure under DIAGNOSTIC: Door
Switch, page 1; however, 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).
➔
With the door properly closed, the ohmmeter
should indicate a closed circuit (0–2
Ω
).
➔
If not, replace the door switch assembly. See
figure 11, page 8; and Removing the Front
Panel/Drum Assembly, page 9.
