F30 or F31 - Open or shorted RTD sensor probe

What does F30/F31 mean?

These codes indicate a problem with the oven's RTD (Resistance Temperature Detector) sensor probe or its associated wiring. F30 means an open circuit, and F31 means a short circuit. These codes typically appear when the oven is active or attempts to become active.

• Open circuit in the probe wiring
• Shorted RTD sensor probe
• Faulty RTD sensor probe (resistance does not match chart)

Click steps to track your progress.

1. 1

   Check the wiring in the probe circuit for any signs of an open condition or damage.

2. 2

   Check the RTD resistance at room temperature and compare it to the probe resistance chart; replace the RTD sensor probe if the resistance is incorrect.

3. 3

   Allow the oven to cool down completely, then restart the desired function.

4. 4

   If the problem persists, replace the display board.
