How to Replace the Oven Temprature Sensor on a Frigidaire Oven

The oven temperature sensor in a Frigidaire oven detects the temperature within the oven compartment. The sensor allows the oven controls to maintain the temperature set by the user. If the oven displays an F3 code, the temperature sensor may be faulty and require replacement. Replacement of the oven temperature sensor can be accomplished with a screwdriver and basic mechanical skills.

  1. Disconnect the power from the oven.

  2. Move the oven out away from the wall.

  3. Remove the two screws from the top of the back panel that hold the back panel to the body of the oven. Lift the back cover up and then remove it from the oven unit.

  4. Unplug the oven temperature sensor wire connector by depressing the connector lock tab with your fingers and then pulling off the connector.
