What F3 Means
F3 is a humidity sensor fault, relevant on Advantium/speed-oven-style units with sensor-cook features — the sensor that reads steam/humidity for auto-cook programs isn't giving a valid reading.
Common Causes of F3
- Sensor vent is coated with grease or food residue
- Sensor has failed
🔧 One Safe Check You Can Try
This doesn't affect manual time/power cooking, so you can continue using standard settings while scheduling service for the sensor-cook features.
⚠ Why You Shouldn't Go Further Than That
- None — this only affects the automatic sensor-cook feature, so it's safe to keep using manual settings while scheduling service.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
