It is radiated rf from the blower motor. This rf is not coming in on the line but is radiated directly to your system. Sometimes moving cables around or moving your preamp around could help but this is a real difficult problem to eliminate other than not running the blower when listening
Help on Electronic Problem
I have a fireplace in the room where I have my stereo and when the fireplace powers up the blower to dissipate heat from the fireplace, I hear static (sometimes loud static) coming through my speakers. I have a PS audio power purifier that I plug my system into. Yet I still hear the static (whether music is playing or not). What is this and what do I do?

I would guess the fan motor is a Shaded Pole type motor. As a rule this type of motor would not cause the problem the OP is experiencing. At this point the OP needs to contribute more information..... . |
When it is about to have the fan go on, the static starts... often the static stops once the fan is on (though, not always). Sounds like the fan is controlled by a thermostat. Automatically turns on and off? I still think it is a faulty wiring issue, poor electrical connection, or a faulty contact. The thermostat could be a line stat or maybe low voltage that controls a relay that turns the fan on and off. Best thing to do is call a service tech and have it checked out. Be thankful the static is not an intermittent problem where it only happens once and a while. Those are the worst to diagnose. You want it to act up when the tech checks it out. Jim |
