Display shows 'Probe Err' or meat probe error and food probe readings are inaccurate or missing.

Safety first: Unplug the grill before cleaning the probe jack or opening the controller.

• Check connection: Ensure the GMG meat probe is fully inserted into the probe jack on the controller.
• Inspect cable: Look for cuts, kinks, or melted sections of the probe cable. Replace if damaged.
• Clean jack: Use a cotton swab and a small amount of electrical contact cleaner to clean the probe jack on the controller.
• Test with another probe: If available, plug in a known-good GMG meat probe. If the error clears, the original probe is faulty.
• Replace controller: If multiple good probes fail to read and the jack is clean, the probe input circuit on the control board may be bad and the board should be replaced.
