It's an inherently poor design. The loud tone is caused by the number of fan blades spinning per minute in a small chamber that resonates like a bell, and pure ringing tones transmit farther than "pink noise." My cell phone app measured loudness at 46db, which is the same as watching TV 8 feet away. Not acceptable.
The boxes are manufacturered by robots, so there's very little variation. Exchanging it for another would not help much.
You could always open the box and cut the wires to the fan--or get Comcast to change the design. I have mine in a cabinet with doors
Hello, recently I had to take my Comcast DVR/HD in and get a new one as the HD was going, most everything I recorded would have one or two sections where the content was pixelated and would freeze and then come back, eventually to freeze and not play. So I lost a portion of my shows and some I could get onDemand. So I took my old DVR in, I'm not sure now what model it was. Comcast gave me the PA PX013ANM and I brought it home, plugged it in and was able to get it connected but it had a fan noise that was so loud, I could hear it even when watching the tv and sitting near it at my desk. So I took it back and they gave me a new one. I came home, set that up and it could not get past the three dots showing it was in process but never went beyond. I tried looking on the Xfinity site and nothing helped. So I took it back the next day and they gave me the third one. I brought it home and have hooked it up and it is recording and running just fine... but it is also loud. I can hear the fan of the DVR box all the time. It is slightly quieter than the first one but still louder than the one I had to return originally. I'm sitting here typing this with my TV off and the DVR hums loud enough that it is annoying. Is this model known for being loud?
Thank you in advance for any help,
I can close which helps a lot, but it does built up a lot of heat in there.
