Hi JW
i have a 2016 freedom elite 22fe. mine does the exact same thing after being shut up for a couple of days. that is with the lp valve shut and batteries set to store. i am not saying its right but it alarmed me the first time and since i when i enter the coach i take a look at it since it is under dinette. as long as it goes out (from blinking red to steady green) after opening the coach up to air out. alarm has never gone off and in the owners manual they talk about the fumes caused from the construction materials. i just attribute it to that. at least i know it is working..
