Customer Questions and Answers for Controller by Frigidaire

Hello Mike, You will want to check the wiring of your oven sensor. The F3 error code inicates an open oven temperature sensor. If wiring is ok then do a resistance check on the sensor and it should ohm out at 1090 ohms. If not correct then replace the sensor 316490001. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
