Hi, when the oven is set to bake at 350 the temperature will swing from 327 to 417 or more. There doesn't seem to be any temp consistency at any pre-set temp. Is this the temp sensor or control board?

Dean for Model Number RF263LXTB0

ANSWER Dean, You will want to check the temp sensor for resistance. At room temperature the sensor should be 1090 ohms. If outside of 10% of this then the sensor is bad and would need to be replaced. If this checks ok then the oven control board is faulty and would need to be replaced.
