Wolf Range Error Codes — Complete List

Wolf's built-in ovens and ranges keep a compact display-code set, and the meanings shift sharply between model families: on L Series wall ovens F1 is a door-lock sensing fault and COMM ERR a lost link to the oven controller, wall ovens spell out 'Probe Shorted' when the temperature probe fails, and the legacy dual-fuel range flags an open RTD oven sensor as err 03. All four codes below trace to Wolf's own support pages — the one genuinely owner-fixable item is the probe replacement Wolf documents itself; almost everything else resolves to a circuit-breaker reset or a factory-certified service visit.

• F1 F1 on a Wolf L Series wall oven is a door-lock sensing fault: the control didn't see the lock or unlock switches within 60 seconds while driving the door-lock motor.
• COMM ERR (Comm Err, COM ERR) COMM ERR on a Wolf L Series built-in oven means the control panel lost communication with the oven controller — Wolf's own cause is exactly 'communication lost with the oven controller.'
• Probe Shorted (PROBE SHORTED) 'Probe Shorted' on a Wolf L Series or E Series wall oven means the temperature probe has failed — and unlike most Wolf codes, the documented fix is a part you can replace yourself.
• 03 (err 03, err 3, Error Code 3) err 03 on a Wolf Legacy dual fuel range declares an open circuit on the RTD oven temperature sensor — often with the cooling fans running non-stop.

Don't see your code?

Wolf reuses its letters differently across generations (an F1 that means door lock on an L Series wall oven names another fault on a newer range), so confirm your exact model family before treating any code as a diagnosis — and never force an oven door that won't open.
