No. Age is background information alongside the identified fault, condition, parts and access. A remote description cannot establish the remaining life or exact repair outcome.
Understanding this situation
An older appliance may have a straightforward issue, while a newer one can have a more involved problem. Warranty or existing service arrangements also need checking independently.
A useful next step
Provide the model and history and ask what the proposed assessment or repair covers. Make a decision from the actual findings and your needs rather than a universal age cutoff or an assumed component failure.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
