If the window is when the Cover Down / Stop..." message is displayed on the
frontĆpanel, then the test has failed.
If the window is when the Cover Up / Stop..." message is displayed on the
frontĆpanel, then the test has failed.
If the test fails, try replacing the following components:
1 Window sensor page 6Ć20.
2 FrontĆpanel assembly page 6Ć18.
3 Main PCA page 6Ć9.
Only replace one component at a time and perform the “Window Sensor” test again before
replacing another component. Using this procedure you will be able to determine exactly which
component failed.
