Try a reset at the breaker. If it comes back, it needs a visit. ### Can I keep using my Hestan oven with ERR04? Yes, Hestan says the oven can still be operated without the affected feature. Book service soon rather than living with it. ### Which Hestan oven codes mean I should stop cooking? Hestan treats ERR04, ERR05, ERR08 and ERR20 as non-critical. Any other code on the oven is critical: reset at the breaker, and if it stays, do not use the oven. ### Does a breaker reset clear ERR04 on a Hestan stove? Sometimes. If the code comes back after the reset, the part behind it needs a technician. --- **[Read on the site: Hestan stove showing ERR04 on the oven | StoveRepair.center](https://stoverepair.center/error-codes/hestan-err04/)** **[Book a visit with StoveRepair.center](https://stoverepair.center/schedule/)**
