GE GDT645SYN0FS upper rack: WD28X25479 superseded
GE's exact GDT645SYN0FS UPPER RACK ASSEMBLY diagram identifies complete upper rack WD28X25479 at item 615 and explicitly lists WD28X35778 as its replacement. Right slide WD30X29858 (item 650), left slide WD30X29859 (item 652), bracket/roller WD12X22801 (item 680), and middle spray assembly are separately identified. This gives a model-specific check for a damaged rack versus a slide/bracket issue.
Safety boundary
- Support a loaded rack before releasing any stop or removing it. Follow the exact-model manual, and stop if either slide or its bracket is bent or loose.
Compatibility requires a direct model listing, explicit supersession, or equivalent manufacturer evidence.
Required identifiers
- Complete GE model from label: GDT645SYN0FS
- Diagram item 615: WD28X25479
- GE replacement: WD28X35778
- Identify right slide item 650 and left slide item 652 separately
Compatibility rules
- GE's exact GDT645SYN0FS diagram maps item 615 WD28X25479 to replacement WD28X35778.
- The diagram separately names right slide WD30X29858, left slide WD30X29859, and bracket/roller WD12X22801.

Never assume
- The upper rack replacement includes both track slides, brackets, rollers, a middle spray assembly, or bottle-washer parts.
- A right-side slide and left-side slide use the same part number.
- All GDT645 variants have identical rack hardware.

Left and right slides are distinct
Item 650 is the right slide WD30X29858; item 652 is the left slide WD30X29859. The diagram also lists bracket/roller WD12X22801 and middle spray components separately.
Confirm the suffix
Match all characters, including 0FS. If the model label differs, use GE’s exact-model parts lookup again.
