Wolf oven with temperature probe feature shows E30 and will not start a probe cook cycle.

Safety: Turn off power before accessing internal wiring.

Basic checks:

• Inspect the meat probe cable and tip for cuts, kinks, or burn marks.
• Clean the probe jack in the oven wall with a dry cotton swab to remove grease or moisture.
• Try a known-good Wolf-compatible probe if available.

Internal checks:

• Access the rear of the probe jack and inspect wiring to the control board.
• Test continuity of the probe and wiring harness.

Corrective actions:

• Replace a damaged meat probe first; this is the most common failure.
• If the jack or wiring is damaged, replace the probe receptacle assembly.
• If E30 persists with a new probe and intact wiring, the control board probe circuit may be faulty and require replacement.
