I have a 2011 model MES 40 that I received for Christmas. I have been getting great results with no issues. Today I started a 6Lb Brisket and a 4Lb Pastrami at 7AM. The MES was set at 230*F and both the MES and my MAV 732 read 230* after 30 minutes. Outside temp was 66*F with a light breeze. A large Roasting Pan with Veg for Au Jus was placed on the 3rd shelf down with the Brisket on 1 and Pastrami on 2. I figured the Pan may block some heat so I bent in the sides for more circulation...
10AM Brisky at 136* IT
Strami at 119* IT
Set Pt at 230* MES reads 235*
MAV reads 217*F This is ok because I try to stay <225*F for Brisky.
2PM Brisky at 154* IT
Strami at 148* IT
Set Pt at 230* MES reads 225*n Element is on.
MAV reads 210 Temps a little low but in a heat cycle. Still normal.
7PM Brisky at 176* IT This was rising slowly after 4hour stall. Removed Au Jus pan for better heat circulation.
Strami at 170* IT
Set Pt at 230* MES reads 235* Element is off.
MAV reads 230*
Here is where it gets weird... MAV Temp drops to 210* over about 15 mins and Brisky IT starts to drop and the MES Meat probe in the Strami reads " - - -" !?!
15 more mins and MAV is reading 200* but Set Pt at 230*and MES reads 235*, the Element is off!!!! What is happening?
I cycle the Power with the Remote, and reset time and the Set Pt to 230* but now the MES reads 205* and the Element comes ON!!!
The temps rise on the MES and the MAV to 230* and Brisky IT rises to 178* All seems back to normal.
15 minutes later THE SAME CRAP STARTS AGAIN!!! MAV temp drops to 208*, Brisky drops 2* and MES Meat probe reads, " - - - " then 170* IT.
The Set Pt is 230* the MES says it is 234* The Element is OFF.
The temp on the MAV keeps dropping...I pull the meat, shut down the MES and all goes in a 350*F Oven to finish.
7:52 PM The Brisky is at 200*F...
I have no clue what happened. Suggestions???...JJ
