Dome thermos bending?

SkinnyV · February 2016

I just tried to pull my large dome thermo out and it took some force and actually chipped some glaze on the way out. Thing is it was bent, I didn't push it into anything during a cook. I checked my other eggs and it seems like these thermos bend on their own, or is it just me?

There should have been just a clip holding it in place on the inside of the dome.

Carolina Q · February 2016

If too much crud builds up on the shaft, it can be difficult to remove. If you had to twist and tug to remove it, I would suggest recalibrating. Never had a bent one though.

@stompbox, the clip is unnecessary and even gets in the way sometimes. Many of us removed it and tossed it in the trash years ago.

I've had my dome thermometer bend and I contributing it to cooking two pork buts on CGW's, adjustable rack (one on each rack). It dome is so heavy, that you never really feel that the thermometer is hitting the food. Now, I always make sure I position the top but just slightly toward the back.

As above, toss the clip (or use it as a drip pan spacer) and get yourself a wine cork to run the thermo stem through and then into the BGE. Gives you more clearance and if you impale any food you won't bend the stem. FWIW-

+1 On that.

The temp gauge stem is stainless steel. It's not going to warp or bend as your cooking.

PSHome said above, dome is heavy and you would probably not even feel it bend as it was lowered against the food.

SkinnyV · February 2016

Yeah no clip, I'd argue that it does bend on its own as I don't remember cooking anything high in the dome making contact but ok. Just found it odd,

It sticks down lower in the dome than you think. Pork Butt cooked indirect at felt/gasket level could hit. Also depends on the placement/angle of the hole drilled in your dome. I have seen big differences on some Eggs over the years.
You never know...lol

+100

I have a couple thousand wine corks, and I will add that as another use for them. I have used them for so many things.

Have corked mine for years. Works

After I got a TelTru therm, as it was longer than OEM, I half-corked it. Best reason for doing that was to be able to rotate the therm dial to the set target temp at 12 o'clock, so you can easily see want the temp is from far away.

Toxarch · February 2016

I still use the clip on mine but I added a 1/2" copper pipe coupler between the thermometer and the dome. It made a good spacer to get it away from the food and still reads the temp fine.

Mattman3969 · February 2016

2 of my 3 are bent but I'm pretty sure my Dutch Oven is responsible for it. They still work fine.

Do you have to 'soak the cork' Just kidding, couldn't resist.

So how exactly do you do the cork mod on a mini? Assume the probe will not fall out if the lid is up with only the cork.

no it will not fall out. Just take a nail or drill bit or something close in thickness and poke through cork. Slide thermometer in hole. Don't put too much force or you could damage thermometer.

cactusjk · April 2016

About how long should the cork be ~1"? Thanks for the help. I have had a LBGE since 1997 and have decided to get smarter!

Toxarch · April 2016

I have a large. I bought a 1/2" copper pipe coupler, put it between the thermometer and the dome, and left the clip on the inside of the dome.

I have used a whole cork and cut on in half. As long as you have enough of the tip in the dome to get accurate reading you are good.

All you have to do is flip the clip thing and put the thermo back through.

Can someone post a oicture of what has been described with the wine cork? I can't seem to picture ir.

westernbbq · April 2016

Ive bent at least five thermos probes, especially when using rig extender and multigrid system from cgs. I always make a mental note to remove the thermo before a high in the dome cook and i always forget. Too many beers?
Anyway, injust use bent probes. I wish bge made a shorter stem thermo but that idea of placing clip on outside of dome is brilliant. Ill try it

I rely heavily on guru and use guru reading to fine tune dome thermo calibration by clipping guru on dome thermo probe. I usually need to adjust one a year.

@matoch ... look under the thermometer dial in the first and third picture of this thread:

Corks are free, but if you want to go with a different look use wooden toy wheels. Staining and finishing them is optional though!

They don't bend on their own. It's from hitting a pork butt, turkey, etc. as you close it

Happened to my large a long time ago

Thanks. I was clearly over complicating it. That is as simple as it was described

castironman · April 2016

I currently have mine set like @Lit demonstrated above. Simple and works with cooks up on the AR extender (Large Egg).

If the temperature shown is the average of the entire stem.. does the exposed stem outside the dome skew the reading?

I am curious if anyone has ever tried to clip a few inches off the thermometer stem? or is there a quality aftermarket short stem thermo that would allow the gauge to sit lower profile?

fishlessman · April 2016

just curious with the cork users, have you checked the same temp with and without the cork. my 2.5 inch teltru measures low by a little more than 10 percent compared to a 4 inch stem. it doesnt make a difference with most cooks but i do compensate with low and slows by adding 10 percent to the gage reading

On my slow cooks I use my grate probe to get that temp and go by that. I think the cork may alter slightly but not enough to make a huge difference.

@castironman ... this is one of the FAQs ( http://www.teltru.com/t-faq.aspx ) addressed on the Tell-Tru website:

- Is a bimetal thermometer tip sensitive?

Yes. For the most accurate temperature reading the stem must be immersed into the medium at least 2-3". Unique to all Tel-Tru bimetal thermometers is a groove on the stem that equals the minimum immersion depth so you won't have to measure.

I would make sure that the groove/dent is inside the dome a quarter inch or so ... otherwise the ceramic temps will contribute towards dampening temp swings.
