My wife was so proud of herself when she bought a new Samsung side by side
refrigerator with energy saving compressor. Yes, it runs quiet and doesn't
use much juice, but the compressor drive has a 5 KHz supply, and as luck
would have it, it wipes out all the HF bands every 5 KHz. To make matters
worse, beside the 5 KHz birdie there's serious hash between the birdies. If
I want to operate, I kill the breaker to the refrigerator. This isn't doing
the fridge any good. I threatened to return the fridge but she threatened
other things. I may find a way to make it self-destruct.
I called Samsung USA and they kept me on the phone for a half hour looking
for any tech support inside Samsung USA who might know of a fix. (My guess
is, inadequate shielding and probably a square wave generator). No dice....
they are not aware of this problem.
Any help out there? The warranty isn't expired yet, but I will be removing
screws in the next few days. I may get lucky with some simple shielding
(Already wrapped the AC cord in ferrites)
In the meantime, BEWARE of Samsung energy saving refrigerators. If you are
considering any top-end refrigerator, take a portable radio with you to the
appliance store and make them turn the unit on to full cooling.
