Oven display shows F13, and the meat probe or core temperature sensor function does not work (on models with a probe).

Safety first: Disconnect power before accessing internal probe wiring.

User-level checks:

• Ensure the original Liebherr meat probe is used and fully inserted into the probe socket.
• Inspect the probe cable for cuts, kinks, or exposed wires; replace the probe if damaged.
• Clean the probe plug and socket gently with a dry cloth to remove grease or moisture.

Internal checks:

• From the outside, access the back of the probe socket and inspect wiring to the control board.
• Test continuity through the probe and from the socket to the board; repair or replace the socket if open.
• If wiring and the probe are good, the probe input circuit on the control board may be defective.

After replacing the probe or socket, test the meat probe function in a suitable cooking program.
