Display shows PRB or probe error; meat probe temperature does not display or reads 0°F/– – –.

Safety first: Unplug the grill before inspecting jacks or wiring.

Steps to troubleshoot PRB error:

• Check probe connection: Ensure the meat probe plug is fully inserted into the probe jack on the controller. A partial insertion can cause no reading.
• Inspect probe cable: Look for cuts, melted insulation, or kinks in the probe cable. Replace the probe if damaged.
• Test with another probe: If available, plug in a known-good Recteq-compatible meat probe. If the new probe works, the original probe is faulty.
• Inspect jack: Examine the probe jack on the controller for debris, grease, or corrosion. Clean gently with a cotton swab and electrical contact cleaner.
• Controller input check: If no probe works in that jack, the controller's probe input may be defective and the controller may need replacement.

Note: A PRB error typically does not prevent the grill from operating, but meat temperatures will be unreliable until the issue is resolved.
