The ac cooling fan usually will come on with high outside temps over 85 usually as well as high ac pressures with the ac running.It can run from low to high speed as needed to cool the ac condensor to allow proper ac operation.If it is actin up compared to how it used to work I would have the freon checked to see if your model is low on freon at all as this can cause this type of fault here.If found low the leak needs located and repaired and the freon refilled to correct this issue.If this is o.k. let me know.
