Hi. We have a mystery we are trying to solve. Last month we were in Hawaii when a cold snap occurred (low ~26F). When we got home and checked on the boat, the carbon monoxide alarm in the v-berth was going off and when we turned on the DC panel, the LPG alarm started sounding. The carbmon monoxide detector in the salon was not going off - we checked the batteries and it was working.
Since that we time we haven't had either alarm go off again, but carbon monoxide isn't something to mess around with and because the LPG alam was going off, we suspect this somehow is related to the propane tank for cooking. At the time we had two Airydryers on and nothing else and the boat hadn't been started in a few weeks (Hawaii was lovely!).
Our next step is to check the line between the solenoid to the range by turning on stove and then turning off range and propane tank and seeing if the pressure goes down. But we want to understand the source of the problem. We are struggling to figure out how a propane leak (if we have one) would lead to a carbon monoxide alarm going off - doesn't propane need combustion to generate carbon monoxide? Ideas, thoughts appreciated.
