GE JBP28DR1BB surface-unit fit guide
GE lists 6-inch surface-unit item WB30T10111 with explicit replacement WB30X24401 and 8-inch item WB30T10110 with replacement WB30X24400. Separate diagram rows identify the 6-inch and 8-inch black bowls WB31T10014 and WB31T10015.
Safety boundary
- This is a model-to-part identity reference, not an installation guide.
- Do not remove or handle electric range surface-unit items while energized; use qualified service for replacement.
Compatibility requires a direct model listing, explicit supersession, or equivalent manufacturer evidence.
Models explicitly covered
These model identities have the source evidence listed below. Read the part decision and suffix limits before ordering.
- JBP28DR1BB · Check model references · Manufacturer evidence ↗
Required identifiers
- Complete appliance model: JBP28DR1BB
- Manufacturer diagram section and item number
- Original and replacement identifiers exactly as shown in the GE model diagram
Compatibility rules
- This guide reports GE Appliances Parts diagram fitment for exact model JBP28DR1BB; keep the full model suffix when checking fit.
- Only a replacement arrow explicitly shown by GE is described as a supersession; no cross-model inference is made.
- Part identity is not an instruction to install or repair the component. Use the exact owner manual for permitted filter or accessory care; arrange qualified service when access requires disassembly or electrical work.
Never assume
- Do not infer fit for neighboring model suffixes or a different color/revision from this exact diagram.
- Do not infer that a symptom proves any listed part has failed.
- Do not treat a superseded part number as cross-model fit evidence.
Exact-model diagram items
6-inch surface unit assembly: GE diagram item 56 lists WB30T10111 → WB30X24401 (explicit GE replacement). 8-inch surface unit assembly: GE diagram item 57 lists WB30T10110 → WB30X24400 (explicit GE replacement). 6-inch black porcelain burner bowl: GE diagram item 59 lists WB31T10014. 8-inch black porcelain burner bowl: GE diagram item 60 lists WB31T10015.
Fit boundary
The diagram assigns separate item numbers to the two element sizes and two bowls. Verify the complete range model before ordering; no other JBP model’s listing is used to establish fit here.
GE lists these rows under exact model JBP28DR1BB. The source page does not establish fit for other suffixes; verify the full appliance label and source diagram before ordering.
Component function and access
The diagram separates surface-unit assemblies from porcelain burner bowls and identifies the elements by 6-inch and 8-inch size. These are different component types; match each diagram item to the exact range model.
