F10 error displayed during baking. oven would not shut off and continued to
heat. We cut power to the oven, let it cool down . Repowered it and set it
for 375 degrees, monitored temp with extra oven thermometer. It heated up to temperature normally, but did not stop heating and at 500+ degrees we shut the oven down by hitting the cancel button. I have check the RTD ohms appear consistent with chart for different temperatures. Is there something else we need to check before ordering EOC.
