Here is a service manual.

I had to use a third part site as the maual is too big to attach through this site.

Your wiring diagram looks the same as the one on Page 6-1.

The error looks like a grounded element error.
I am not sure if each element is about 27 ohms or if they are a combined resistance of 267 ohms but the 200 ohms meter resistance scale should let you check them.

Check the heating coil.
Unplug the unit and the common wires that goes to all the elements.
Check each element with a meter.
They all should have continuity.
Then check from each side of the elements to the case/frame, all should be infinite ohms (open). If not the coil may have sagged or broken and is touching the case. This can cause it to run on high and the control board cannot regulate.

If you do not own a meter, I would suggest you purchase a one. You can get a decent digital multimeter for under $20.00. You do not need fancy though it is nice if the leads are a couple feet long.
If it saves ordering one unnecessary part it has paid for itself and you end up owning a useful tool.
Most places will not let you return electrical parts so if you order it, you own it.
A couple things to watch when measuring ohms and continuity
1. Always remove power from the machine otherwise you could blow your meter.
2. Always disconnect at least one side of any device you are checking. This eliminates the possibility of measuring an alternate/parallel circuit path.
3. When checking for closed contacts and continuity use the lowest scale (Usually 200 ohms). Then try higher scales. This scale is 0 to 200 ohms so if the device you are measuring is 300 ohms this scale would show an open circuit which it is not, you are just measuring outside the scale's dynamic range.
4. When you start always short the meter leads together. This will tell you that the meter is working and if there is any 0 offset.

There is a good STICKY at the start of this forum about it's use.
