Fuse 6 on the MCU PWB has blown.
NOTE: Remove the cause of Fuse meltdown before replacing the MCU PWB.
When turning the power OFF, turn OFF the power switch first and then the main power switch.
Chip fuses on the MCU PWB seldom fail because of an internal MCU problem. The cause is
almost always a short circuit in the wiring or components fed by the fuse. You MUST determine
the source of the short before replacing the MCU PWB.
Procedure
1.
Check the Tray Module PWB
