Time for a new furnace. Does anyone have any RFI experience, positive or negative, with an Amana variable 2-speed gas furnace? Thanks! 73, George VE3YV / K8HI ________________________________________
If it were me, I would not rely on past reports. manufactures change specs, change parts suppliers, etc... I told my heating company when I replaced my heater, that I did not care what they installed
Dave has given good advice. I'll add that variable-speed motor controllers are a well known cause of RFI. 73, Jim K9YC I told my heating company when I replaced my heater, that I did not care what th

Dave has been doing excellent work on this, moving the ball forward. I've incorporated it into the talks and writing that I do on chasing RFI. 73, Jim K9YC http://nk7z.net/sdr-rfi-survey-p1/ ________
Even some non-variable-speed setups can emit RFI. In 2010 I needed a new system, and specified no variable speed to the contractor. I got a Trane system that had a G.E. ECM (electronically commutated
Hi again, Be sure to define what no RFI means to the installer in a way you can test, and prove, and document how the test is to be made, and what the levels are to be under. If I remember correctly,
I agree with Jim and Dave. However I'm a bit confused in the variable 2 speed. Is it variable or 2 speed? Normally all the H & V guys I talked to said, 2 speed, OR variable. Two speed was just that,
I too was a bit confused when I first read that. Variable speed blowers are ECM (electronically commutated motor). The motor has 3 windings, and a rotor with permanent magnets glued to it. Speed is d
My Carrier Infinity model has one of those motors, they cost about $800 if one goes out. A few years ago mine took the deep six, but I have a gas company service plus so it didnt cost me anything. I
To say that one either Has Noise or doesn't have Noise with a Furnace or any other device one needs to do a little qualifying along with that statement. If you have enough "Other Noises" then you wou
Thanks to all for the insights. I was looking to see if someone had specific experience with this manufacturer and/or model. As for the advice on recourse in the event of problems: I have requested t
Respectfully-- my noise level is low enough now that I can use it as a standard. I now have about an S2 background RFI noise on 40, and most nights atmospherics are much worse, so I almost never hear
