6. Using Figure 9, check for the resistance
values of the motor’s Main and Start
winding coils as shown below.
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.
7. Check the belt switch by measuring resis-
tance between the two light blue wires, as
shown in Figure 10, while pushing up the
belt switch pulley.
Iftheresistancereadinggoesfrominnity•
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.
If the Start winding is in question and the •
resistance is much greater than 4 ohms,
replace the motor.

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).
With the door properly closed, the ohm-•
meter should indicate a closed circuit
(0–2 ohms).
If not, replace the door switch assembly.•
TEST #3 Heater Test
This test is performed when either of the
following situations occur:
Dryer does not heat•
Heat will not shut off•
This test checks the components making up
the heating circuit. The following items are
