by following procedure under TEST #7:
Door Switch, page 22; however, if this was
not done, the following can be performed
9. Reach under the drum, (raise it as far as it will go), and

push the idler pulley arm, on the back of the drive motor,
an ohmmeter across ACU J8-3 (neutral, white
to the left to relieve the tension on the belt, then remove
wire) and J8-4 (door, tan wire).
the belt from the pulley.
10. Slide the belt off the front of the drum and remove belt.
With the door properly closed, the ohmmeter
should indicate a closed circuit (0–2 ).
If not, check harnesses and connections
between ACU and door switch. If good,
replace the door switch assembly.
5. Motor Circuit Check - Access the ACU and
measure the resistance across J8-4 and J9-1.
If resistance across J8-4 and J9-1 is in
the range of 1 to 6 , the motor circuit is
acceptable. Replace the ACU.
Otherwise, continue to step 6.
6. Check the wiring and components in the path
between these measurement points by referring
to the appropriate wiring diagram (gas or electric)
on pages 26 or 27. NOTE: To access motor
system components, slide the top back and
remove the front panel.
