What to do if mirror doors aren't responding?

If you are using DFMTCS to control the mirror doors, the "MIRROR DOORS" switch should be switched to "OPEN" on the MDC.

Also, the "DRIVES" & "MTR DRIVER CHASSIS" switch should be enabled and the "HALT MOTORS" button should be unpressed.

If you are still having an issue, there may be an issue with the mirror doors nesting improperly hardware issue requiring hammer time.
