Well, already got a minor problem with the '87 Casa Vieja... there seems to be a "knock, knock" sound coming from near the top of the motor. It is only present sometimes, but does this on ALL speeds and even when coasting. It has a K55 and it's been installed out of the box for about 2 months now. It's not very loud (but it is noticeable), and there is no wobble. Any suggestions?

Look inside the motor to see if anything might be loose. If it's not that, it's probably an unbalenced rotor hittting the stator. |

My dining room Charleston makes a "knocking" noise on the highest speed similar to the one your described. It does it for about 2-3 seconds at a time, in intervals of about 30 seconds in between. It has gotten worse and is starting to annoy me. I thought it was coming from its little flywheel, but it is from within the motor. I cannot find a damn thing loose either. Is it wear in the shaft of the motor? I ask this since I have worked on some antque protable fans that made a similar noise caused by the gap formed between the shaft and the motor, it allows the shaft to move in and out while the fan is moving and makes it bang. Could this be the same thing in my Fasco? It is one of the earliest Charlestons, the first "body style."

You're probably talking about end play. Almost all sleeve baring motors have it. An average ceiling fan motor has ball bearings. Ball bearings don't wear as fast as sleeve bearings. After a while, a sleeve bearing will start to wear out, causing the rotor to come in contact with the iron stator. the best thing to do is to discect the fan and the motor and find out exactly what is wrong. |

In-and-out movement of the shaft is not a problem, if there's too much play you can add fiber washers. Side-to-side movement of the shaft indicates bad bearings.
Open up the motor and see if there's anything loose or brushing, and while you're in there oil the bearings.

At my family's Vacation Spot, the supposibly 1987 Unknown Hugger with Light Kit in the Back Bedroom make a "Knock,Knock" sound simmaler to yours. The other fans in Bedrooms are (Slightly) Quiet. I always refered to it as a "Swishing" sound. The one in the Dining Room is Very Quiet.

With huggers, it's easy for a wire nut inside the housing to find it's way to the rotating parts. |

They're not K55 fans. Wrong thread. But if you balance them I presume the knocking will go away.

it will be crap in about 5 years because of all the grease and stuff that can collect in and on the fan. it is a very quiet fan. no hum no buzz no wobble no click.
