Does anybody have any data of what the cause(s)of RV frig/freezer fires are?

I can't find any info. Nothing on manufactures web sites. And most news stories end with "cause of fire unknown" or fire investigation continues type thing.
Thanks

And you never will.. Any manufacturer certainally is not going to list how their products fail.

Everyone knows how the Norcolds fail. Dunno about the rest

Does it matter? There is plenty of opportunity with these devices. Can be propane leak or ammonia leak. Both are flammable. And there should be a spark or flame to start the fire of course, which can be caused by electrical circuits of the fridge or by propane burner. Can burn out peacefully without a propane or ammonia leak as well (if something starts the fire) - there is plenty of wood in the cabinet and plastic.

If you are really worried and losing your sleep over it, consider a 120V or 12V compressor fridge.

You could search your state or the national Fire Incident Reporting System for info, but - as others have already said....why??.[emoticon]

BTW - very difficult to do a good fire investigation when the source area (and usually the entire RV) are destroyed..[emoticon]

OK maybe I should of explained a little bit more. I'm going to upgrade all elect in coming months and considering putting in halogen fire extinguishers system for frig/freezer. http://www.firefightproducts.com/Fire_Fight_Supplemental_Hal.html But I'm wondering if some type of temp readout (readable from cab and bunk area)might be better. Best I can figure out, the fires are from "high temperature sensor" or "boiler" plate that fails. Don't know if that is certain brands or certain models or both. If I had someway of knowing frig was getting up in temps by a digital readout and alarm I could do something about it before temps ignited something, maybe alarm goes off at 700 degrees?. But if these fires are from a some type of spark when something fails, not much use to monitor temps IMO. That's why I'm wondering about the exact cause of fire if anybody knows.

If my memory is correct from reading on this forum the 120 volt heating element that makes the refrigerator work on 120v, was a few watts larger than normal, and caused the boiler tube to crack and leak the flammable coolant.

If you are going to upgrade to an all electric coach as you imply, just get a compressor or household fridge. I bet you don't have a fire suppression system at home.

I don't know the specifics of what caused ours but in our case the heat shield did its job. The charring was mostly near the bottom but some higher up as well. If the heat shield had not been there I imagine the whole coach would have gone up. One of those shiver up the spine moments when we pulled the nocold out.

Half the time when your fridge is running you are not even there. A lot of good will fire exitinguishers will do then [emoticon]

There are 2 distinct reasons for these to catch fire- basically one is a sudden release of refrigerant *while running on LP*. This is fairly rare, as the largest component of the refrigerant is water, but it can and has caused fires. The more common failure is simple overheating, which will ignite surrounding flammable materials.
There are other reasons they will burn- electrical problems, critters nesting around the burner, etc.
