Two weeks ago I was walking past the steps leading to the basement, and I noticed that ol' familiar electrical burning smell. Not overpowering, without any visible smoke, but enough to set off the alarm bells in this Ham's cranium.
I went downstairs to find the smell emanating from our clothes dryer. The top was very hot and the smell became even stronger after I shut it off and opened the dryer door. Fearing a lint trap fire, I gave the lint duct a touch with the back of my hand to see if that was warm. Compared to the dryer itself, it was stone cold. I went outside to the vent opening on the house and gave a good sniff. Nothing from that end either.
Convinced and relieved that the house was not in danger, I unplugged both the washer and the dryer and let them sit. The dryer cooled off. I wasn't sure what the exact cause was, but I suspect that the control circuit board had gone again, as it did a few years back. The odor was identical to that of either burnt components or traces on a circuit board.
The matching washer had been giving us its own problems for over a year now. I decided that it was time to purchase a new pair. My wife didn't object to my statement that I didn't want a fire hazard in our house.
We went to Lowes, one of the big box hardware stores where Marianne picked out a pair of machines manufactured by Samsung. I was a little wary. Our cellphones and TV are from Samsung, but our washer and dryers have always been Whirlpool, Maytag or even GE going back to my parent's house.
They were delivered a week ago; and as Marianne seems happy with them, I didn't give much more thought to them - until yesterday. I was downstairs listening to not much on 20 Meters, when Marianne came down to put in a load of laundry. I was about to answer a lone CQ from UA3EDQ when I thought to myself, "Here we go!"
Our last pair of washer and dryer were notorious RF generators. If I was on the radio and Marianne put in a load of wash, I could literally hear the agitator motor in my earbuds. I could heard the motor rev up and die down during the spin cycle. The dryer wasn't as bad, but was still a nuisance.
To my delight and surprise the Samsung pair are the antithesis! I was able to work Igor without having to listen through RF hash. Both the washer and dryer are RF silent on 20 Meters. I checked the other bands as well, and they all seem to be free from washer and dryer hash.
So kudos to Samsung! Whatever and however these machines were engineered, they seem to be Amateur Radio friendly!
