Just the tip…

While cleaning and inspecting the big king for this upcoming season I noticed the tip of the cat probe looks a little worse for wear. I think it worked ok last season although it never went past probably 230 position but I had some hot fires. It does settle down back to the first tick mark when cold.

Nice "Wedding Crashers" reference.

I dunno about the probe though. I burn my stove too hot on occasion (more than 1800 degrees), but mine has never looked like that.

Water getting down the flue at any point contributing to rust?

😎 glad ya got the reference. How old is your probe? Mine is circa 2014

No, but even if it did it wouldn’t effect the probe at least on a BK.

Could be just baked from the last 11 years of high heat. I’d just replace it

Yea I agree, I’m gonna get one on the way tomorrow.

Not sure. I broke a few of 'em. I think they got too hot and the little spot weld that holds the inside of the coil spring broke.

They do that. Mine looks even worse right now. Seems to be a corrosive metal rod with a protective coating that peels off. The whole purpose of the probe is to conduct heat so it’s just a solid rod with no internal moving parts. I figure as long as it’s still the full length it’s good.
