Display shows ERR12; meat probe temperature jumps erratically or reads extremely high.

Safety first: Allow the probe to cool before handling.

• Clean probe: Wipe the probe tip and cable with a damp cloth and mild detergent to remove grease. Dry thoroughly, especially around the connector.
• Inspect insulation: Look for melted or cracked insulation along the cable. If bare wires are visible, replace the probe.
• Test with another probe: Plug in a different Gourmet Grillson-compatible probe. If the error clears, discard the faulty probe.
• Check jack: If multiple probes show ERR12, inspect the probe jack for debris or bent contacts. Clean gently and, if necessary, replace the control board containing the jack.
