Dedicated line problem

The system is in the living room and I can go into the bedroom and turn on/off the ceiling fan and hear the noise through the speakers.

Hello Glory,
I had a similar situation in my home/system. I tried everything to get rid of it (drove me nuts), and finally determined a bad earth ground was the major culprit. I dug up the ground rod by the meter base, and found the thing in a very rusted condition, and the clamps attaching the ground wire had deteriated. I removed the ground clamp, vigorously power wire-brushed the area, used a new and better ground clamp, and then covered that section with automotive undercoating to preserve the connection.
It seems the probelem can appear also when extremely dry conditions occur, causing a less-than-perfect grounding. A good soaking with a sprinkler can help.

I don't know if this will help you, but it sure helped in my instance.
Good luck,
Dan

Glory:
Understood that the system is in the living room. Understood that the ceiling fan is in the bedroom. What Apachefl is asking is 'are you sure that the circuit that powers the ceiling fan is NOT taken from (taped from) the living room circuit'?

Understood that you built the house. Do you have a relationship with the wiring installer? He could likely answer this question. If not, what I would do, first, is take down enough of the ceiling fan that I could temporarily install the 'broadcast end' of a circuit tester and then take the 'finder end' and go back to the service panel and find which of the breakers is feeding this circuit. There may be more sophisticated (easier to hook up) circuit testers, but this is the only type the I have used. This may answer this question.

In houses that have a 'production wiring job', it has been my experience that there are many 'shortcuts' that may be taken to make the job 'easier'. IF, and that may be a big if, the ceiling fan fan 'fed' from your dedicated circuit, what you are experiencing would certainly be a likely outcome.

The other thing that I would suggest from my experience (I completely re-wired our home and installed new service panels), is to carefully check and make sure that your ground system is clean, tight and well earthed with adequate ground rods coupled together.

The best way to dedicate a circuit(s) for a home system would be a seperate sub panel with all the dedicated outlets connected to it. No other lighting fans or dishwasers just outlets. Any problems you know where the source is
