f1 f3 f1 error message wiil not turn on

[PS Staff - Sheila]

You may have two problems.

The F 1 code stands for a faulty clock control board.

The F 3 code stands for a faulty oven temperature sensor.

You can check the sensor it should have a resistance of 1100 ohms at room temperature.

If the sensor check out then replace the control.
