How to Fix / Troubleshooting
Safety: Disconnect power before servicing.
- Identify affected modes: Note which cooking modes trigger E19 (e.g., convection roast, bake, broil). This helps isolate the affected circuit.
- Inspect wiring: Trace wiring from the control board to components used in the failing mode (e.g., convection fan, specific element). Look for shorts or damage.
- Check configuration: Some Sub-Zero ovens require configuration after control replacement. Verify that the control is correctly set for your model per the service documentation.
- Replace control board: If wiring and components are good, replace the main control board, ensuring the correct part number for your exact model.
