A suffix or production reference can distinguish versions with different fittings or components. A model family name alone may not identify the correct replacement item.
What the observation tells you
Two refrigerators can look almost identical while using different shelf supports, controls or door hardware. Omitting the final characters can therefore lead to an unsuitable part. A retailer's abbreviated product title is not always the full reference from the rating plate.
A useful next step
Copy the label exactly and keep a clear photograph. Provide the position and description of the damaged fitting as well. Let the supplier verify compatibility before purchase rather than relying on approximate dimensions or appearance.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
