propane leak detector

[Donjones]

2018 R27 o/b. The propane leak detector next to the stove will not stay quiet. Goes off several times a day even though the entire system has been shut down and checked. In fact the stove has never even been used. Any advice would be helpful. Thank you.

I have had to replace our C0 and propane detectors several times. It seems they have a "shelf" life and it's not helped if they sat in a warehouse or on a store shelf for an extended period before they got installed. I think the sensors get dusty, dirty, and/or any reagent or whatever breaks down.
