My jbs 07 m1bb, the oven temp runs away,overheats,at any setting

CHECK YOUR USER'S MANUAL BECAUSE I HAVE NEVER HEARD OF A CONTROLLED TEMP DURING BROIL AND JENN AIR HAS GREAT WEB SITE FOR HELP AND INFO

run away temp either temp probe or EOC board is the problem

Sounds like the oven thermostat stuck, for whatever reason and then the oven overheat thermostat kicked in. At the very least, I think you will need a new oven thermostat and possibly an overheat one as well. On the 720 there are two, one for each oven, so when you take the oven to bits, check both out.

Hello, Thank You for using FixYa. I will be helping you today.This is normal..When you set the oven to say 350 that means the avarage cooking temp is 350.There is nothing wrong.
Thank You and please rate my answer if it was helpful..

The F2 error code is for the temp sensor. The temp sensor is mounted inside the oven cavity & regulates the oven set temperature. If the temp sensor fails the oven could overheat. This is what generates the error codes. I recommend having the temp sensor checked with an ohm meter, at room temperature the sensor should ohm out at approx 1100 ohms. If the sensor checks ok, then the control will need to be replaced.

Assuming the clock/timer has not been accidentally set, and this is what is turning it off, does everything go off on the oven including the lights and the display on the oven control?
If it does, then it could be the oven overheat thermostat kicking in.
Also is the cooling fan running normally in the background because if it isn't, this will cause the oven to overheat.

The temp probe resistance should read between 1050 and 1150 ohms. If not. Replace it.It causes the overheating situation you describe.

depending on madle you either have a bad themostat, or the newer ovens use an electronic thermistor, not sensing proper temp and shutting off
