I ran the oven self-cleaning program last night, set for 3 hours. Two hours into the cleaning, Fault Code F2 appeared with beeps - I pushed Cancel and it stopped. 15 minutes later, Fault Code F3 appeared with beeps - I again pushed Cancel and the Fault indication (and the cleaning program) stopped. The convection fan continued to run so I cut all power to the unit for sleep purposes. This morning I restored power and twice have seen Fault Code F2 with beeps. Help please. By the way, I replaced the relay board six months ago.
Sounds like an oven sensor (AP4009009) problem. The control board detected an over temperature and then either determined the sensor was open or shorted and flagged the error. The sensor is located in the back and looks like a metal pencil. You can try removing it and slowly pull the connector out the front. Using a multimeter, you can check for about 1080 ohms of resistance when at room temperature. If it reads open, shorted, or anything way off from the expected reading, it needs to be replaced.
