Fridge not working on propane

We recently had a problem with our 179 where the fridge would go into alarm every 2 minutes indicating the door was open. The dealer identified a loose ground wire as the fault (or at least I hope it was.) The fridge did the same thing in every mode. Since this was a short trip to the Keys, we ended up using it as a ice box and buying ice to keep food cold. I had already scheduled an appointment to get another minor item fixed when we got back. 

Nice to hear they're still out there. We've found 1. Still waiting to find that place that has a mess of them. Wine caps and oysters have been strong.

Bingo! Found spiders in the burner and chimney. Compressed air took care of the little critters. It's making ice cubes now.

We had gone out Memorial Day and it worked fine. Didn't take long to get gummed up. Seems like a fine line between functional and not working with the propane. We'll have to watch that closer.

Thanks for all the suggestions.

Wasps just build nests, and hornets build mud nests.  Leaf cutter bees etc lay eggs in small holes and crevices, then pack chewed up leaves in on top.  Then repeat the cycle until whatever depth the hole or tube is full then try elsewhere.  Also, small spiders leave egg cases of white web in holes and tubes.  Those are quite tenacious to remove.   Maybe they aren't a problem in the east but they sure are in the intermountain west.

Wasps and leaf cutter bees work havoc on small spaces and holes, tubes, etc..  Leaf cutter bees and orchard mason bees were the main pollinators before the honey bee was introduced to the eastern US in the early 1800s, and are supposedly more efficient than honey bees.
