I had a brand new fan from Lowes and needed a repair part. Called Lowes service parts line. No parts available. Called the vendor's parts line. No parts available. I figure everything comes from China now and they don't bother with repair parts on small items like fans.

Last time I needed some home depot had them. Just google "ceiling fan replacement blades" and you will find many options. They are generic, you don't need to match the original parts exactly, just pick the same length.

If you can't get an exact replacement blade, you should replace all the blades on the fan. A different blade would likely not weigh exactly the same as the other, original blades and this could cause wobbling and premature wear on the fan.

Agreed, I assumed (always a bad idea) one would know to keep the blades matched up for balance.
