Samsung Range FE710DRS/XAA error code E-0C

[ckmccollim]

I have a Samsung electric range FE710DRS/XAA with an error code E-0C
Does anyone have a service manual that would tell what this E-0C error code means? (It was in error code memory 5 times.)

The oven will come up to correct temp when first started, but then after reaching temp, it will not hold this temp. If oven (while still hot) is shut off and then turned back on and set to the same temp, it will show the correct lower temp (because it has fallen) and run temp back up to correct set temp.
The only problem so far that I can find is the one bake element terminal is showing a poor electrical connection (like it is getting hot.) The wire by the terminal is discolored and the wire inside the terminal is also discolored. The terminal on the bake element is 1/4" spade. What is the best way to fix terminal on wire harness?

Thank you for any help.
