Safety Checks You Can Do

Steps you can try at home safely

• Verify your home's circuit breaker has not tripped; check the 240V breaker dedicated to the oven and reset if necessary • Ensure the oven door is fully closed and latched properly • Confirm the oven is receiving proper electrical power by checking for lights and display function • Turn off the circuit breaker to the oven for 60 seconds, then turn it back on to perform a complete system reset • Allow the oven to cool completely before attempting to use it again • Check that no cooking debris or moisture is blocking the sensor area near the back wall of the oven cavity • Verify you are not using any incompatible cookware or accessories that may interfere with sensor operation • Review your oven's manual for correct temperature settings and ensure no unusual settings were accidentally changed • If error persists after reset, discontinue use and contact a certified KitchenAid service technician for professional sensor replacement
