I am getting F3 code when heating oven up to 375°F. I replaced the sensor but still cant get oven to heat. I can put on 450°F and after 5 minutes get the F2 code. What do you suggest?
Answer Hello Kim,
F3 is the fault code for an open oven sensor. You should go to the control board, remove the connector to the temperature sensor, and test for 1100 ohms at room temperature. Be sure to tap on the sensor when performing the test. If it is bad, you will need to access the sensor connector at the back of the sensor and test again for the same value. If it is there, the harness has failed. If not, the sensor WB21X5301 has failed. If the sensor and harness test good, you will need to replace the control WB27K5140. The F2 fault code indicates an over-temperature condition. This was most likely caused by the previous condition. From the condition you described, it sounds like a harness or control issue.
