--- title: "Wolf stove showing ERR OC in the knob window" description: "What ERR OC means on Wolf stoves, what to check before booking, and when it is not a failure at all." url: "https://stoverepair.center/error-codes/wolf-err-oc/" --- # Wolf stove showing ERR OC ERR OC in the knob window of an older Wolf dual-fuel stove means the knob stopped talking to the oven controller. ## What ERR OC actually means. ERR OC in the knob window of an older Wolf dual-fuel stove means the knob stopped talking to the oven controller. Wolf's own fix starts with the metal contacts on the knob stem. Wolf stove display What to do when ERR OC shows on the stove ### Kind of code Knobs, keys and display A key on the panel was held down too long, reported a press nobody made, or stopped answering; or a knob's switch told the stove it was on when it was off. Water, a spill or grease worked in behind a knob is ruled out first, then the switch, the key panel and the cable to the board. If a burner keeps heating while the keys or knobs do nothing, switch the stove off at the breaker. ### Usually leads to Knob and switch replacement Stove knobs that are cracked, loose or spin in place, and the switches behind them that leave a burner stuck on high or dead, replaced at the knob, the stem or the switch. ### Shows up as Stove Knob Broken or Loose A knob spins without doing anything, wobbles, falls off in your hand, has cracked, or will not turn at all, so you cannot set a burner or the oven properly. ### Make Wolf A Sub-Zero Group cooking brand from Wisconsin; owners often know it on sight by its red knobs. ### Source Wolf answer: legacy dual-fuel, ERR OC Older Wolf dual-fuel stoves whose oven selector knob has a small display window.

Switch the stove's breaker off. If it comes back, it needs a visit. ### I wiped down my Wolf stove knobs and now one shows ERR OC. Why? Moisture or cleaner on the metal contacts of the knob stem can break the connection to the control. Dry the stem, reseat the knob with the power off, and the message often clears. ### Can a loose knob on a Wolf stove cause ERR OC? Yes. The knob has to seat fully so its contacts touch the control, so a knob that wobbles or sits out can lose the connection. ### Does ERR OC on a Wolf stove mean the knob must be replaced? Not always. Cleaning and reseating come first, and a new knob or a repair behind the panel only if the message stays. --- **[Read on the site: Wolf stove showing ERR OC in the knob window](https://stoverepair.center/error-codes/wolf-err-oc/)** **[Book a visit with StoveRepair.center](https://stoverepair.center/schedule/)**
