No power to propane detector

[kebrita]

Thank you all so much for all your advice and guidance. We are now the proud owners of a 2012 - 30' Classic Limited.

As we all know, anything that can go wrong will....and on our first night sleeping in our airstream - at 4AM the propane sensor goes off - scaring the living daylights out of our dog, Lucy.

After watching all the youtube we could find (at 4 AM) , it turns out these sensors only last 7 years and woohoo - it's 2019........so we were not being poisoned. There was nothing we could do in that moment, but cut it out so we could all go back to sleep. We knew were safe as long as the propane was off.

After buying a new propane detector and rewiring as it was, we are getting no power to the sensor. After finding the 12 volt panel to see if any of the circuits needed to be reset - this didn't help, but in addition, we have lost power to the 12 volt outlet next to the stereo. HELP please.......

Hi - congrats and welcome.

A few quick thoughts.

While the sensors may have an average 7 year life - that doesn’t mean they all die the exact same time. Yours may have been functional and telling you something - even if your propane was “off”. It could have been as simple as the dog vented some unfresh wind in the general direction of the sensor (search that here, it’s a thing), or, you could have a fixture that’s leaking - even with the tanks “off” they might not be 100% closed or there could have been propane in the pipes after the tanks. I wouldn’t mess with it - the alarm tells you something so you want to be sure you know the message.

As for rewiring it - I suspect when you cut the original wire you didn’t turn the breaker off first. It’s possible cutting the live wire tripped a breaker somewhere. Look at the entire panel. Also wonder if it’s possible you popped a ground fault circuit. Our external outlet and bathroom outlet are on a ground fault circuit that connects to something else I’m forgetting right now. We had something not getting power - no breakers tripped - and resetting the bathroom ground fault switch corrected it. So perhaps try that?

You’ve now got the the depths of my “knowledge” in this area. Hopefully someone who actually knows what they’re talking about will chime in soon!

Good luck!!

There is a separate inline fuse to the propane detector that comes off the positive busbar in my 2017 FC25FB. You can see the fuse holder in the bottom-left corner of the bottom-left corner picture here: http://www.airforums.com/forums/atta...0&d=1539352234

I had a hard time figuring out why there was no light signal on the expired propane detector and none on the replacement I installed. I felt it had to be a fuse, but couldn't find one in the area of the device, looking from the device to where the cable disappeared into a nest of sheathed cable.

Airstream suggested the bus board in the coach, but there was no indication any fuse controlled the inline fuse for the propane detector.

Then the rep talked to a tech, who pointed me to the bus board in the exterior compartment under the bed in my 2012 Flying Cloud 27 FB, and there it was, on the left as you look into the compartment behind a plywood board that holds the light: an unattached cable with a solid 1 amp fuse. The prior owner must have disconnected it for some reason.

I pass this along for the next reader of this string trying to find the inline fuse and cable!
