BUT, I do have two dimmers in my house that I know of at this, that I haven't gotten rid of yet. I had no idea they could contribute to an issue such as this. I'll have to swap them out the next time I make it to Lowes or Home Depot.øøøøøøø wrote: ↑Sat Mar 16, 2019 7:18 amOther devices (besides dimmer switches) that use triacs and can therefore cause noise:
Motion sensing lights
Electric heating devices
Basically, if something is cheap, simple, and variable... it could contain triac-based attenuation and therefore cause noise.
These insidious beasts cause EMI (and even RFI) due to noise at the turn-on and turn-off point. They're switching many times per second. They make all of the wiring in the wall into an antenna that radiates interference.
Any time there's a mysterious noise it's worth searching to see if there's any dimmer-like object around. The noise doesn't radiate from the device itself... it radiates from anywhere utility power runs in the walls, etc.
A strong chance that many of your problems disappear when you do, particularly if the dimmers are old or inexpensive
