Safety Checks You Can Do

Steps you can try at home safely

• Turn off the circuit breaker supplying power to the oven for 60 seconds, then switch it back on to reset the control system • Verify the oven door is fully closed and latched securely, then attempt to clear the error • Check that the oven is properly connected to its 240V dedicated circuit and not sharing a breaker with other appliances • Inspect the visible area around the oven door seal for any food debris or obstructions that may trigger the temperature sensor • Allow the oven to cool completely for at least 30 minutes before attempting any troubleshooting steps • Unplug the oven for 5 minutes if it has a plug-in connection, then plug back in to perform a hard reset • Check your home's main electrical panel to ensure the breaker dedicated to the oven has not tripped • Review the oven's control panel settings to confirm no lock or delay-start mode is engaged • Consult your KitchenAid manual to verify you are reading the error code correctly • Contact a certified KitchenAid repair technician if error persists after reset, as internal component replacement may be required
