Incorrect (IMHO) - it very well could blow up on you. Prestos are made of stainless steel which is much more forgiving, AA's are cast aluminum. Steel alloys have a fracture toughness index of 50, aluminum is only 14-28.

I just ran my PC dry, started with what I thought was plenty of water but 90 min had it down to about 1 oz left. Burnt grains despite having them elevated, but I am running another batch. So far it seems to be fine,

We had a local news story about PC blowing up at somebody's apartment and all the windows were gone after "boom". I'm not kidding. It happened in 2011.
People outside the house thought it was a bomb and police sent the "bomb team".
I just read what I said and it was written funny. But I'm not joking.
Nobody got injured thought.

As posted MANY TIMES now. It is unsafe... If you use it "and it just cracks" it WILL fly across the room. What does you AAC921. Weigh? Now do you want that flying across the room hitting you in the back of the head? Didn't think so.. Plus the fact that it would be spuing super heated steam..

I believe you are incorrect as well. Most all larger pressure cookers now a days are aluminum. I know, I just bought one not to long ago. Presto, Mirro, and many other companies are making aluminum pressure cookers now a days, at least in the larger sizes. While you can still find Stainless Steel ones, they are much more expensive and are generally 8 quarts or smaller.

Could be. Still irrelevant IMHO - the OP has a cast aluminum PC. If you've ever had any real experience working with aluminum - drilled it, welded it, compressed it in a vise, etc. and still want to take the risk of heating up a possibly compromised aluminum casting to 250 degrees F full of gaseous H20 at 15psi and a load of glass hars, have at it, lol. As always just MHO.

Yes, like a water heater, if it split, it would be fucking gone! You could send a 40lb. cannon ball through your wall into the next house. Do not underestimate that kind of pressure!
People who are in the know with pressurized gasses know that if they rupture, they become dyslexic missiles!
I wouldn't risk it at all, if AA gives you the go ahead after inspection, awesome! If not, who knows, they may offer you a discount on a new one.
Either way, if it were to create a boom or become a projectile, your life would get shitty fast!

i have the AA921 and it says in the book that came with it that your cooker can fail if it has boiled dry. send it back to them to inspect. i dont think they put that in there for shits and giggles. the AA921 weighs 26lbs + jars and water its not something to take a chance with. or at least I wouldnt.

it is a HEAVY cast and does come with a 50 yes 50 year warranty so i think its pretty tuff

Thanks guys.... I ran it through 2 loads yesterday to 15PSI for 90+ minutes
The seal held fine, and there are no warps anywhere on the PC. The lid and everything looks to be ok. The jars didn't even dry out while in there FYI
I Might be over exaggerated on the time it sat on the heat, It might have been closer to 30-45 minutes with no water from cold to turning off the burner.
Unless Someone wants to buy it for $150 + shipping, I'll send it back to AA for inspection as soon as I can afford to.
Thank you everyone for you're concern, I'll take head and stick to 1 spawn bag at a time in my 6QT presto for now

I hear ya - I have an AA 931 and they're heavy duty (and heavy when packed with 14 qts, lol). But aluminum engine blocks are "tuff" too - able to contain controlled fuel explosions, yet they warp and crack all the time if they're heat stressed.
If it only went for 30 minutes maybe it's fine - I'm no metallurgist but personally I'd still get it inspected myself. Maybe they have one of those stress analysis scopes:

Things also stress crack when they are un evenly heated. The bottom of your pressure cooker was far hotter then the top. This is why when you ride a 2 stroke high compression dirt bike on a strait road without easing off the throttle (un even heat, kinda like running a pc dry) pressure cracks form in the piston, causing it to explode, and you fuck your cylinder, crank, and piston. Easing off the the throttle, and giving more even heat your piston will last 50 hours at least. Redlining it, you have 30 minutes, tops..
Professional racers change their piston after every race, cylinders after every 2 races. Intermediate riders change it every 20 hours.. Its a fact the heat stressed cast aluminum (and other metals) do, and will crack, or rupture when exposed to stress. I know you have already run it, but I would still be a bit cautious when using it. I know AA's are tough, and thick, and have a 50 year warranty. But if you dry run it, the warranty is void instantly.. I'm almost willing to bet that AA has something withing the core of the metal that melts at 270*f so that they know if you have dry run your unit.. (I would if I warrantied something like that)..
Its your house, your life, and your neighbors that will possibly call the cops on you when that thing blows the fuck up putting a hole in your wall. *if you could pressurize your house, it would explode at 2psi.. Doesn't seem like a lot does it?.. Well its true. Now take your 15psi pressure cooker, damage it, and risk your life. Its your call..

Hey OP, if you do send it back for inspection, please post here what the results are and what the total cost was for shipping/inspection.
Also, I don't know if you use a hot plate or not, but I got an outdoor 15amp timer for $5 at a thrift shop that I use on a heavy duty hot plate and set for 90 mins after my PC gets up to pressure. I realize it probably wouldn't have helped in this case - but for me, I end up getting busy doing other things, on the phone, etc. and I could easily space the thing and let it run for 3hrs or so - I almost did. Just an idea - I dread the thought of ruining my AA and know I could do it pretty easily so I try to mitigate the possibility that way.

Na, idk what everyones tripping about. Ive run my PC dry and the most that happened was i cracked the jars and dried the grain. OP should b able to tell if his PC is ok or not. If there was a danger of an explosion, i would hope he has the kinda PC that has a saftey blowout stopper.. I would be too much hassole for me to send it in someplace to tell me if its fine or not

u You want 15 psi, but i I can understand if u you only can go up to 5 psi.. i I think ur your problem is [that] u you say u you have had it on high for 60 minutes..
i I PC my grain at 15psi for 45-50 minutes at medium-high..
u You dont don't want to crank up the heat bro. It'll dry out ur your grain as well. U You just want enough heat to make the water start boiling, but not a crazy high rolling boil. I think it may work for u you at 5psi, but try turning the heat down a little. i I usually turn my knob about 60% of the way up works for me. idk how your stove works thou though
Fixed. Now that it's understandable, I can see that you totally missed the point.
PS> Also, you don't sterilize your grains for long enough. 90 minutes.
Just saying, ive done it for years and never go longer than 60 minutes. I aim for 45-50 and have always been fine. Honest. i use WBS

Well Like I said, I did run it twice, and it went fine, the seal held no issues etc..
The questionable part is not weather the seal and the safety mechanisms will hold, it whether the steal will crack and explode out of the side, sending the PC hurling through walls etc.
I will almost for sure send it in, as since it works, I'd like the safty knowledge knowing that i'm safe in continuing to run it.
I just need the time now to get this thing boxed and shipped!
