Dome Thermometer Crash?

So I was egging tonight, getting her fired up, getting ready to cook some beef kabobs with chimichurri sauce (BGE cookbook - fantastic). I was waiting for the dome to come up to 450. It got to 400, and suddenly as I was sitting there watching it, the bottom fell out of the temperature. Needle quickly fell back to zero. Anyone else ever have this happen?

    Most likely the bi-metallic coil in the thermometer broke.  Fairly common in bi-metallic (almost all mechanical) thermometers.  If that's the case, it's ruined.   86 it and buy another.

    Oh I'm pretty sure it's done, no question. Is there something better I could replace it with? Not saying this will happen again, but if I need to buy a new one....

    It was probably defective, or you wrapped it around one too many times.  How old is it?  There's some kind of warranty, maybe you can get a replacement under it.

    Check it out to see if it was the BGE version or a Tel-Tru. Most eggs sold over the past couple of years have Tel-Trus, which were the common replacement when the BGE thermo quit. Some have had a Tel-Tru for years with no issues, others it quits in a year or two. Like Nola says, garbage and get a new one. 
    I suggest if you do clean burns, take it out. The bi-metalic in my Broil King gasser is over 12 years old, it is a Tel-Tru (or so it says) and is still working fine.

    Definitely a Tel Tru. My Egg is less than a year old.

    Less than a year, it is under warranty, I think.....
    Ask your dealer.

    Using skiddy's link, you have one year, according to that warranty.

    I had one fail like your thermometer did. Mine was over a year old so I bought a replacement from Tel Tru for around $25.

    @nola, is there really no other alternative? A digital one which can handle the heat? There ought to be one in the industrial world, surely.

    Just about every kiln and oven made now days has a digital thermostat.  Look at Thermoworks web site - they make probes that are rated well over 1000 F.  You can certainly put a thermocouple in the dome thermo hole and use a digital thermometer.
