Well, my detector was clean, but I blew all around it anyway. When it started chirping a couple of months ago, I replaced the battery, with no change. Since this battery was a little weak from the once a minute or so chirp over the last couple of months, I replaced it again, but this time I cleaned up the terminals with a pencil erasure, and all is good now. Not to totally hijack Wade's thread, but I also checked out the CO detector, as well as the propane detector. Besides checking the propane detector with the test button, I light a butane lighter, blow it out while keeping the button engaged, and then hold it close to the detector for 15 seconds or so, and the alarm should go off. I then test the mute button, and wait for the green lite to come back on.
Keep us on our toes, Wade.
