Turn off the burners and the oven. If it comes back, it needs a visit. ### Why would my Wolf stove report high voltage? It can come from the utility supply, a loose neutral in the house wiring or a problem at the stove's own connection. The stove only reports what it measures, so the supply is checked first. ### Can I keep cooking on my Wolf stove with 3C20 showing? Wolf gives no owner steps for 3C20. Keep the stove off until the supply has been checked, since high voltage can damage the controls. ### Which Wolf stoves show 3C20? Wolf lists it for its newer dual-fuel models such as the DF3050, DF3650, DF4850 and DF6050. Older dual-fuel models with a knob display use a different list. --- **[Read on the site: Wolf dual-fuel stove showing 3C20 | StoveRepair.center](https://stoverepair.center/error-codes/wolf-3c20/)** **[Book a visit with StoveRepair.center](https://stoverepair.center/schedule/)**
