Topband: OT - LG Dryer RFI

[Rick Kunath]

I have a Whirlpool front loading washer and dryer here. I had the 
factory send a technician out and they installed the RFI suppression kit 
on both of them. They argued a bit with me about the installation and 
the cost of the parts. As I left it I paid for the kit and they did the 
install for free on both units. I can just barely hear the fact that 
they're running if I really listen and I am using an indoor loop. 
Outside I hear no difference. The service technician also told me that 
on these modern dryers unless you're going right from the vent outlet 
through the wall behind the dryer you need a booster blower inline. My 
dryer vents through a rooftop vent so I installed a blower-type booster 
inline with the vent in the attic. That made a huge difference in the 
dryer run time. It's pressure sensing so you install it and forget it. 
It comes with a small panel display you can mount if you want to and 
that lets you know it's started or if you ever need to clean it (I have 
never had to do that).

I also had 2 Trane air conditioning compressors and air handler/gas 
furnaces installed to replace failing older systems, all variable speed. 
I had contacted Trane about the RFI kits on both of the compressor units 
and both of the air handlers before I bought them. They installed these 
RFI kits for free and my installation company put those kits in at their 
shop before they came out and did the install. Also nice and quiet.
