Assembly Considerations
Reassembly of the TIB door is generally the reverse order of the disassembly steps given
above.
Display Panel
The replacement display panel has a protective plastic sheet on the glass surface. Remove
this prior to mounting on the door.
When replacing the mounting nuts, use between 3 and 5 inch-pounds of torque. Do not
overtighten.
Wire Ties
Three wire ties are required on the display steel slab. See the exploded view above and the
illustration below for installation locations.
When installing the wire tie for the LCD connector, orient the head flat to keep it clear of the
protective cover when it is reinstalled.
