I have a Kent Tile Fire Stove that has an air flow lever in the front of the stove. The lever gets stuck when trying to move it to open the air flow, and I have to give it a really good wack every time I want to open it.

I've tried spraying WD-40 on it, but after it gets hot, it all burns off, and the lever get's stuck again. Is there lubrication that can handle the high heat wood stoves generate?

Thanks!

Pete
 
First I would look into why its getting stuck. Something along the lines of corrosion or a warped part that can be repaired. Beyond that, look for a heavy duty silicone, good to about 400-450°F. I think WD-40 is about half that. Another option is Break Free CLP, a gun lubricant, good to about 400. Just make sure whatever you use the problem isnt compounded by attracting more debris.

Great, thanks, I will try them. Well I don't think it's warped, because when I spray WD-40 on it, it works fine. It just burns off right away. Thanks again..
 
I use gear oil. 90 weight is what I have. I tried various high temp greases but they always turned into a chalk and went away. The gear lube seeps into cracks and seems to cure into a film.

Yes, it will stink at first when it gets hot.
 
Oh, ugh...burnt gear fluid. If it smells like it does coming out of a rear diff, I wouldn't try that. Blech.

DH just used some (automotive brake) caliper lube on our door pins over the weekend. So far so good.
 
Never sieze is my standard high temp lube and if that doesn't work powdered graphite.
 
I used a spray by dupont that has teflon in it on my door hinges and was amazed at how well it worked. They sell it at Lowes.
