What F25 Means
F25 means no zero-cross signal was detected on the convection fan and oven lights control board. The board uses the zero-cross of the AC supply to time its switching; the manual checks that L1 and neutral reach its connector before replacing it.
Common Causes of F25
- L1 or neutral not reaching the fan/lights board
- Fan/lights board failed
🔧 One Safe Check You Can Try
Reset at the breaker for 30 seconds.
⚠ Why You Shouldn't Go Further Than That
- Supply checks at the board are live 120 V measurements.
- Board access requires removing range panels.
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.
