2109s Propane Leak
We have a 2012, 2109s and have been on a road trip for 2 weeks. Left the campground that we were staying in for 10 days this morning. We had full hookups there. The refrigerator was, of course, on electricity and we did use the stove, outside grill as well as the furnace on propane. Everything worked fine. When we were checking into a new campground this afternoon, the CO detector in the trailer went off. Went inside, and sure enough, a strong smell of propane. Turned off the valve on the propane tank, opened the windows and started the exhaust fans. Let everything clear and then turned on the valve again. After a couple of minutes, propane smell returned and detector sounded again. Repeated this a couple more times, with the same results. Checked all of the possible suspects; stove knobs, external grill valve, connection to furnace, connection to refrigerator, underneath trailer, with no results. My only suspect is the refrigerator. Turned it off electricity and tried to turn it on gas and it would not switch over.
Any advice would be most helpful?
Thanks in advance.
