LP/CO detector high pitched noise
We just picked up our new 2011 Rockwood Roo 23RS (it sat on the lot for 2 years, but really is "new"). The LP/CO detector tests/resets and seems to be functioning fine, but there is a soft, high ptiched noise constantly and it's driving us nuts. It's definitely not the alarm going off, just a soft but anoying noise.
I've done searches and there were some discussions about this and thinking that the detector needed replacing. Has anyone had luck getting a replacement through the warranty? Even though it's a 2011, we still have the warranty.
