Egg didn't shut down

So we got a new XL egg and cooked some great spatchcock chicken on it last night. After the cook I closed the bottom vent and put the ceramic cap on the dome. All was good until this morning when I opened the egg to get things set for a pork butt and a rack of ribs. I happened to glance out of the kitchen window and saw flames and smoke coming from the egg. I closed the dome and made sure the cap was still secure and the vent still closed. The dome temp went to about 460* and it's still at 410* after an hour has past.
The seal showed no smoke during the cook so I'm sure it's on right. It also past the dollar bill check when we assembled it.
The dome on this new egg has a felt seal so there shouldn't be any air escaping through that path.
The bottom vent is the only place I can think of but still don't understand how it re-lit itself after sitting all night (about 12 hours).
Any clues?
Has anyone had this happen?
BTW: Im not new to the egg. I've had mine for almost three years and this new one was bought for the Daughter.


  • That has happened to me before. I went out next afternoon to lite egg and it was still a little warm from night before. I opened vent and lid and noticed some bright orange at bottom. I added some fresh lump and it was flaming 5 minutes later. I actually thought it was pretty cool.

    Never heard of this, but not really surprised. That is a testament to the thermal qualities of the egg that it would keep an ember going in such a low air flow state. I have heard many times of camp fires relighting after they were thought to be extinguished and the conditions in the egg are far greater for such a event. It would eventually totally extinguish if left closed I'm sure.

    Since many of the eggsperts are tied up (or passed out) in Salado or Melbourne I'll chime it with some morel support and tell you I have never seen this and have no additional thoughts over what you have already mentioned.

    It obviously did not re-light itself, it simply was never out. Air flow somewhere and it pretty much has to be through the egg, in the bottom out the top kind of air flow. 
    Good on you to know the gasket is sealed, so it is either the top and bottom vents or you have a crack in the ceramics.

    How tight is the ceramic cap, does it rock or  have a lot of play?  I lined the caps with leftover gasket material to get a real tight seal. Also, how many hours had elapsed since you shut down last night?

    Windy overnight?   Just a thought

    I also thought the adjustable metal cap seemed to seal better with the top closed than the ceramic top.

    I agree with checking how well the ceramic cap sits and also verify the top hole is flat and doesn't have a low spot around it's circumference that would create an air gap.  The question on how long it had been shut-down and how hot you had been running it before shut-down could be contributing factors.  The fact the egg is insulative will lengthen the time it takes for the embers to cool after being deprived of oxygen, I know my old little smokey joe would extinguish fairly quickly after closing the vents, but black painted metal is an excellent heat conductor and heat dissipator.

    How tight is your lower vent?  Mine is sealed in place with silicone and the sliding screen and cover are fairly tight.

    I would go with @ads75‌ on this one and question the wind. I have never experienced this but if you know your seals are good, the wind forcing air around the lower vent could very well do it. The lower vent seems to me the most likely place for air to get in on a windy night.

    I have to pull my bottom vent out a bit to get itto latch closed . Not just slide it over, it will still have a bit of flow.

    Also, since it is a new egg, do you have sealant around the bottom vent, such as the unfortunate pictures in this thread?

    Thanks to all for the inputs.
    For some answers to questions:
    No wind and I'm sure the bottom vent was closed. It slides about the same as my three year old egg's vent.
    The top cap sits snug and takes two hands to remove due to the seal arount the dome exhaust hole
    It was shut down for > 12 hours.
    The cook was only at 350* so the egg wasn't that hot at all.
    I'll chalk this one up as an anomoly. It certainly makes you more aware of how a supposedly dead campfire comes back to life and starts a forrest fire.
    On the positive side.., It didn't burn any significant amount of lump as it smoldered and it was sure easy to get it up to temp for the rib and butt cook.
    Take care all.
