Mine looks exactly like "liesurelarry's" too and it became so bad that I finally disconnected it. I do have an auxiliary CO (batt-driven...) detector on the wall in the bedroom of my '11 Solera to take care of 1/2 of the original problem and would
think that I could smell any LP gas leaks? Never had an LP detector, etc., on my former '76 Airstream and never a whiff, never a problem.
The former owner of my unit informed me that this was an on-going complaint with these detectors...in fact, he replaced it once before I bought it but to no avail. Maybe Mr. Clemens from FR can weigh in here? Ours first went off after using the furnace(lightly) last October and drove me nutso. Even slapped duct tape over the "mouth" to dampen the incessant chirping. Never a LP smell, nor indicator from the bedroom CO detector. My unit is located to the left of the coach entrance steps and near the disconnect switch.
I WILL SAY THIS THO...after reading all the previous good comments...that when I pulled the detector out from the cavity in the wall I noticed a lot of wood chips and dust within and obviously left during construction of the unit interior from 2011. I plan to go back in and suck that all out with my ShopVac plus gently vacuum the unit itself and\or apply gentle compressed air to it to see if this helps. I might hook it up, one more time, to see if this rights the situation but won't hold my breath?
If I missed anything here please let me know! -PB
