A possibility to consider: We once purchased a motorhome with carpet in the hallway where the propane alarm was located (close to the floor). We treated the carpet with Scotchguard and were then plagued with alarms until we replaced the detector. A tech told us that we had contaminated the sensor in it. So… have you used any cleaning products, air fresheners, etc. near the sensor lately? End result is you’re replacing the detector.
