2.
Reinstalling the Shaft and Door Handle
Once the goods have been removed from the machine and any malfunction of the door lock
mechanism, such as a burned out coil or mechanical interference, has been identified and
repaired, reinstall the components as follows:
1. Install the cover on the door lock mechanism.
2. Insert the shaft into the open door and seat the end of the return spring into retaining hole in
door shaft cam ( Figure 8 and Figure 9 ).

3. Looking at the rear of the door, rotate the shaft counterclockwise about 90 degrees, until the
shaft fully seats into the door. When properly seated, the shaft finger (the latch) will align
with the key way on the door lock mechanism.
4. Install the rear retaining clip on the shaft.
5. Slide the door handle and flange bearing onto the shaft.
6. Install the front thrust bearing and retaining clip on the shaft.
7. Repeat the following sub-steps four times—once for each ball, spring, and set screw: ( Figure
10 and Figure 11 ):
a. Drop the ball into the hole of door handle top spoke, followed by the spring, as shown in
Figure 10 .
b. Install the set screw. As previously stated, the handle should ratchet if more turning force
than necessary is applied or if turned counterclockwise. Tighten the set screw until the set
screw is flush with the handle. This will provide roughly the correct spring tension.
c. Rotate door handle counterclockwise 90 degrees to ratchet it to the next position (with the
next spoke on top).
