What F23 Means
F23 means the oven's pyrolytic self-clean cycle failed to reach its required preheat temperature (roughly 460°F) within the allotted time, so the self-clean function halts before completing.
Common Causes of F23
- Door seal not fully closing, letting heat escape
- Failed or underperforming heating element
- Temperature sensor drift affecting the preheat reading
🔧 One Safe Check You Can Try
Confirm the oven door is closing and sealing fully — even a slightly obstructed door seal can prevent the cavity from reaching pyrolytic temperature, which needs a near-airtight seal to work.
⚠ Why You Shouldn't Go Further Than That
- Confirming whether the door seal, the heating element, or sensor drift is the actual cause requires testing each independently rather than guessing.
- Pyrolytic cycles run at extremely high cavity temperatures, and a door seal that isn't fully sealing during that process is worth confirming carefully rather than repeatedly retrying the cycle.
- Replacing the heating element when the real issue is the door seal means paying for a part that wasn't the problem.
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.
