Robert for Model Number JTP20B0F3BB GE Profile wall oven When the oven is turned on to say 350 it almost immediately ( maybe 5 seconds) says the oven has reached temp. i did see an F3 code. and the Fan is constantly running. My understanding is the temp sensor could be bad for F3 but could possible be the control board.
Answer Robert, You will want to check the oven sensor for resistance. The resistance at room temp should be 1090 ohms. If the resistance is not correct then replace the oven sensor. You will want to do the test from the control board that way you are testing the sensor and wiring. If this checks ok then the control board would be the part that would need to be replaced.
