Possible Causes
Defective function selector switch (mechanical knob models), failed mode relay on main PCB, open circuit to specific heating element or fan
How to Fix / Troubleshooting
Safety first: Disconnect mains power before accessing the control panel or internal wiring.
- Test other modes: Verify which modes work and which do not. This helps identify whether the issue is with a specific element, fan, or selector contact.
- Selector switch check: On knob‑type Etna ovens, remove the control panel and test the function selector switch contacts with a multimeter according to the wiring diagram. Replace the selector switch if the contact for the failing mode is open.
- Element/fan continuity: Test the associated element or fan for continuity. Replace any open component.
- PCB relay: On fully electronic models, identify the relay controlling the failing mode on the main PCB. Inspect for burn marks or cracked solder joints. Replace the main PCB if the relay is defective.
