kitchen aid wall oven shuts off periodically when cooking with the upper oven?
 

any suggestions?
I checked the power connections,breaker is ok ,put amp probe on breaker and only draws 20amps with a 40 amp breaker?

Can you be more specific on the problem?

The normal amount of current drawn by this oven should be written on the name plate (where the model number is).

Gene.
There suppose to be one or two more numbers after "S" in the model number.

after (s) is 0

Just some info

Depending which elements are on and the line voltage you should be able to figure out approximately what the current draw should be.

Also as Gene said
What exactly is happening???

when cooking in upper oven it blows the breaker sometimes after 15 min sometimes it may not, and or if i shut the door hard it may do the same , I think something is loose and causing a short ,What do you think?I even checked all the connections and all seem fine.
Thanks,
Ed

or if i shut the door hard it may do the same
I assume this is only when the upper unit is on and heating.

I think something is loose and causing a short ,What do you think?
I think you are right but finding it is going to be a pain.
If the above I assume is correct then I would concentrate on the wires that have power only when this unit is on.
You will have to do a slow and complete inspection of each wire's insulation.
Would also check the frame for signs of an arc.

If you hear an arc or smell ozone at the oven when it pops the breaker then you know you have an intermittent dead short somewhere.

Gene may have a much better feel for this than I do.

if it were the board in the upper oven ,how much would a new board cost?
