Issue with Coleman propane stove

[LookinUp]

After speaking on the virtues (economy) of a single burner Coleman stove with propane, I've experienced some issues and wonder if I should replace it....first I noticed and oily substance not related to cooking seemingly coming from underneath. I cleaned this up and it happened once again. Now I have noticed that the aluminum connection gets extremely cold, and in addition I don't seem to have much control over the flame..ie  steady but can't really get the flame to increase of decrease. Non of this has caused any issues up to this point but it's making me think perhaps I should buy a replacement just in case. Anyone else experience any of this. I read a post somewhere saying that if the connection gets cold there's possibly a leak, though I haven't discovered one yet with soap.
Thanks

Sounds to me like either you got a bottle with some contaminants in it, and/or possibly had the valve open with the stove or bottle turned sideways and liquid propane (instead of vapor) got into the valve.

Or if its old it just might need replacement.

what stove do you have? the icing is common and does not mean there's a leak. highdesertranger

Thanks, I was a little concerned that it leaked oil...and not from any cooking I did, and couldn't figure from where other than from some internal seal somewhere??
that was a while back and haven't had issues.

The larger 20# propane bottles contain an oil in them. If you are using those an in-line filter would catch the oil.

Why do 20# propane bottles have oil?

 

[John61CT]

Larger? All 20# are the same size, and smaller than most

Larger (than the green bottles) 20# tanks.

Rewording: the larger propane containers, such as 20# bottles, contain oils. But even that is wrong.

Apparently it is plasticizers in the hoses used to connect tanks to propane appliances. The "largeness" of the container is therefore immaterial, although one is more likely to find larger tanks connected by hose than small ones.

The filter (trap, really) catches these fluids before they gum up the appliance.

I regret my bad info and ambiguous phrasing. :-\

No problem.

Hence my comment about making sure to get the right hose type.

Obviously metal is best, required for long runs or behind stuff, but you do need rubber at the last section if you're moving the heater around.

The good stuff is lined with an inner teflon coating to prevent the "breaking down to oil" issue.

Replacing these annually also is a good idea for safety, and inspecting every use.

Actually I'm pretty sure the oil was coming from the stove, not the tank. I'm wondering if there was a seal somewhere that ruptured. I may call Coleman. I also may try taking the stove apart.....that should be interesting

I have had this problem before, and never gave it a thought. Coleman has helped me a few times over the years. They were good to solve my problems with a lantern and stove, both propane.  Coleman fueled products last a long time. Parts do wear out and can be replaced. It's cheaper sometimes to repair than replace, but when you start to have safety concerns, replace it. Call them, the web site is confusing. Wallyworld
