    Today I just repaired my second bad probe. 

    Link to the first one I fixed.  http://www.smokingmeatforums.com/t/133733/whats-inside-the-mavrick-732-probes-easy-to-fix

    This second probe started going wild during a cook.  The pit temp was 225-230 and the probe started to read 350-400 and jumped around so I changed it.  Today when I tried it it would read LLL.

      Grinding down the crimp on the tube

    Just till you open it enough to spread it open

    Then pull it out of the tube. 
    You can see the two crimps and the outer plastic tube under the probe that

    came off pulling it out.

    Plugged it back in and it's still LLL.  Needle nose pliers and crimp both crimps.

    One crimp was tight but the top crimp as soon as I squeezed the pliers it started working.

    Slip on the outer tube till the tip comes through.

    I had to put electrical tape around the crimps because when I tried putting it together with out the tape it read 10* off but with the tape all is good.  Just slide it back in and crimp the end back.  I will get some heat shrink tubing and seal it.

      Both probes read 66 on my counter.

    I hope this helps anyone with probe trouble.  If you don't want to try to fix bad probes don't trash them send them to me..

    I just got my first Maverick. Already have shrink wrap that area plus applied some high temp silicone. Hopefully they will last a while.

    Good luck Flash.  Both of the probes I have that went bad were pit probes.
    Easy to do. Took about ten min mostly looking for this or that.

    Ask away anytime.  The way I see it is  $15.00 is $15.00 never throw away what you can fix.

    That's why I kept the bad probe. Hunting a way to fix it.
     
  8. HANDYMANSTAN,

    Thanks for starting this post and the pictorial. I had a BBQ probe that wasn't working, more often that not it would read LLL. I dug into it following your tutorial and found that the wire was broken at the point of the crimp on the upper lead. I tried opening the crimp thinking I could reuse it but had no luck at that. Using a pair of forceps to hold the wires together I dropped a spot of solder on them and "bingo" we had a read out! To finish the repair I applied a thin shrink tube over the splice with hopes that it would keep it from coming apart in the future. Put everything back together and checked the two probes out side by side and they are reading exactly the same.

    Thank for the post......

    Hey man.... I have been saving a bad probe for several years but it is cut on up the wire partially by a grill lid that blew closed on it in a thunderstorm. Do I have to solder the wires back together or is there a way that I don't have to use my cold smoker soldering iron for soldering? I was waiting for a post like this.

    I am glad the post helped you  azbohunter. 

    Timberjet Yes I would solder the wires where broke then heat shrink over the splice.

    You could use a mechanical  joint instead. Like these but go to a big box and you should be able to get a small pack.
