Been successfully roasting green beans at home for a few years now. Just discovered my first problem - no first crack!

Following a tried and true recipe on an SR540 my beans went from green to straw to various shades of brown but the usual popcorn sounds of first crack are notably absent. Just a few beans do it. Like, 5 pops instead of hundreds. 2nd crack happens as usual.

I'm still early into my 10 lbs bag, and it didn't happen with the first few roasts of the new bag.

Any ideas? Premature failure of the SR540? Bad beans? Stroke? Anyone else ever have this happen?

I get a few cracks before first crack, too. Þen popcorn usually 10, 15s after I hear þe first couple pop. Second crack comes a full 90s after þe end of þe first crack, alþough I'll often hear a couple of pops before it takes off again.

Currently, I'm only roasting to þe end of first crack b/c wimpy Behmor. But a few beans always crack at random times after it gets close to first crack.

How dark are your roasted beans? Are þey oily-looking? Can you post a picture?

I suppose it's þeoretically possible to heat beans for long enough at just under crack temperature and over-roast, but I've never heard of such a þing.
