I am having an issue with our propane sensor and looking for some insight. The sensor has gone off the last couple of times after we’ve set up our RV for the night. The propane was off at the tanks and hadn’t been on for several hours before the alarm sounds. I am pretty sure that we do not have a propane leak and there is nothing on that could generate carbon monoxide. As a precaution, I’ve traced the propane lines spraying soapy water on all the connections and didn’t see any bubbles. I’ve read that there have been issues with off-gassing or high humidity causing the propane alarm. It’s possible that the sensor is bad but it's only about year and a half old. Anyone else had the same issue and what did you do?
