Possible Causes

    • Damaged or faulty temperature sensor (RTD probe) inside the oven cavity • Loose or corroded electrical connections between sensor and control board • Broken wiring harness connecting the temperature probe to the main circuit board • Control board failure or malfunction affecting sensor signal processing • Thermal fuse blown due to electrical surge or power fluctuation on 240V line • Temperature sensor connector loose or improperly seated • Accumulated grease or food debris around sensor probe affecting readings • Power supply voltage irregularities (common in older USA electrical installations)
✅

Safety Checks You Can Do

    • Verify your home's circuit breaker is in the ON position and hasn't tripped; check that the dedicated 240V oven circuit is properly supplying power • Allow the oven to cool completely for at least 30 minutes before attempting any troubleshooting • Ensure the oven door closes completely and latches securely; a partially open door can trigger F9 errors • Perform a full appliance reset by switching OFF the dedicated oven circuit breaker for 60 seconds, then switch it back ON • Check all visible control panel settings and menu displays to ensure no incorrect modes are selected • Wait 5-10 minutes after power reset to see if error code clears during the boot-up sequence • Verify the oven's power cord is fully and firmly connected to the wall outlet (for plug-in models) • Inspect the oven's interior for any loose parts, debris, or damage around the back walls where the sensor may be located • If the error persists after these checks, contact on 844-731-2978 for Asko service technician in the USA—do not attempt to disassemble the appliance
