Rather than arguing about : "is it/isn't it making a high pitched noise" why not record the noise with your video camera, rockybird? If you have a fairly decent video camera with good audio sensitivity, said camera will pick up the noise. I recorded the sounds (or actually a lack thereof) that my Elux induction unit makes, even on boost, with the mic right next to the boiling pot. My camera has a readout display that shows the intensity of basicaly any sound/sounds that it pics up and yes it picks up high frequencies as most better cameras should, and in fact one of my cats "passed gas" during my test and the camera picked it up! I also whispered so folks could get an "idea" of the camera's mic sensitivity. As far as telling which appliance is the "Culprit" turn off the power to one, long enough so you can determine which one it is. In a unit that has "dual compressors" or in your case a compressor for the fridge and one for the freezer,(and using variable speed compressors), it is "very likely" that the compressor "rarely, if at all" shuts fully off. More than likely it will run at it's mininum speed until cooling demands require that the compressor speed up, hence the circuitry that drives the compressor is operating most of the time, and an oscillator in the circuitry is what you "may be" hearing--not saying that you should hear it thou, maybe the circuit board, is not propertly mounted, or insulation aroumd it lacking so it feeds into the frame of the unit, and thus amplifies the sound. Anyway hope you have a good video camera, and at least that will end the arguement "Is it/isn't it making a noise"! Good luck, hope you get it resolved. Gary

HoneyB2, our very own BMore is quoted in that article. There is/was a thread floating somewhere around Discussions. So true, isn't it.

Now that I think about it, the 90° angles I indicated are obvious… It’s really the fact that that middle column is twisted such that it is directly opposite one column but on the other side, the edge of the column is facing into the wall space, or what will be the walls. Hard to explain it! Hope the picture helps.

Reminds me of all the chase scenes across the rooftops of buildings in any cops and robbers show.
