Wolf Legacy Dual Fuel Range Code OC: oven knob lost contact

What OC means

On Wolf Legacy dual fuel ranges, ERR OC is an oven knob message. Communication was lost with the oven controller, and the check points to the metal contacts on the knob. The range cannot read the oven knob position reliably, so the oven may not start or may stop during a cycle. This is a range message and does not apply to wall ovens.

Common causes of OC

Knob metal contacts dirty or worn
Knob not seated properly on the shaft
Link to the oven controller interrupted

✓ One safe check you can try

1. Switch the oven off and let it cool. 2. Pull the oven knob straight off, wipe the metal contacts behind it with a dry cloth, and press it back until it seats. 3. Turn the knob through its range once. 4. If OC returns, stop using the oven and call us.

! Why to stop there

Contacts that look clean can still be worn.
If the controller link is the problem, a knob cleaning will not help.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

OCOC questions

What does ERR OC mean on a legacy dual fuel range?

It says communication with the oven controller was lost, and the knob's metal contacts should be checked. In practice the knob and the controller are not talking properly.

Can I clean the knob contacts myself?

Yes, with the oven off and cool. Pull the knob straight off, wipe the contacts dry and reseat it. Do not use liquid cleaners or tools, and stop if anything looks burned.

Does the cooktop still work?

Typically the burners work independently of the oven knob. If you smell gas at any time, leave the home and call the gas utility from outside.
