Welcome to the forums!


Mine did that on my last trailer but it was hard wired. I had to cut the wire in the middle of the night. Turns out it was too close to the dog bed and well....dog farts


But I didn't know Keystone was using battery CO2 sensors. The easiest fix is to replace it. $20 at Home Depot. If it continues start searching for the source. Where exactly is it locate? CO2 is no joke.


I just did the 360 on your trailer and I don't even see the sensor. It's typically floor level in the kitchen.
