What F2 Means
F2 on older Electrolux built-in wall ovens is a communication problem. The detailed codes are F21, no communication with the auxiliary board, and F23, no communication with the TST board (the glass touch panel). Wiring between controller, auxiliary board and glass panel is checked, then the named board is replaced.
Common Causes of F2
- Harness between controller and auxiliary board (F21)
- Glass touch panel failure (F23)
- Controller not communicating
🔧 One Safe Check You Can Try
Reset at the breaker for 30 seconds.
⚠ Why You Shouldn't Go Further Than That
- The glass panel and boards are behind the oven’s trim.
- Built-in ovens often need to be pulled from the cabinet.
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.
