I purchased 5 harbor breeze fans w/ remote and no pull chain for my home. Not long after purchase one fan acted like the motor was binding up so I returned it for a replacement model. I ended up having to pay extra to get a fan that was close enough to match my other four fans. Now I have two other fans with the same problem. The light works, but the fan barely turns no matter what speed it is on. Any suggestions what the problem is or how to fix it. I went to the Harbor Breeze website and cannot find any contact information everything links back to Lowe's now.

Are you using them with any sort of wall controls?

Yes just a normal wall switch.

Maybe a power switch fried them all. Maybe you got a defective batch. But it sounds like either the receivers, or the capacitors (which are in the receviers) have gone bad. You can try to return them or contact the manufacturer for replacement parts.
