Confirm compatibility first. Handles can differ in mounting orientation, fixing spacing or part version even when their visible shape is similar.
What the observation tells you
A handle also may be supplied with specific caps or fasteners. Swapping parts experimentally can damage otherwise sound fittings and leave both doors awkward to use. The complete model and affected upper or lower door matter.
A useful next step
Ask the supplier to verify the exact part and what is included. Avoid pulling heavily on a loose handle while waiting. Handle compatibility does not address a separate hinge or seal problem.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
