The display shows a PROB error, and the meat probe temperature does not read correctly.

Safety First: Use heat-resistant gloves when handling a hot probe. Allow it to cool if necessary.

Steps:

• Inspect Probe: Check the stainless steel probe and cable for kinks, cuts, or melted insulation. Replace if damaged.
• Check Jack: Unplug and reinsert the probe plug into the Napoleon probe jack several times to clean the contacts.
• Cross-Check: If you have a second Napoleon probe, plug it into the same jack. If the second probe works, the original probe is faulty.
• Jack Test: If multiple probes fail on the same jack, the jack or control board input may be defective and require replacement.
