Possible Causes
Corrupted firmware in main control PCB, Electrostatic discharge event, Power surge damage, Internal microcontroller failure
How to Fix / Troubleshooting
Safety first: Disconnect the oven from mains power.
- Extended power reset: Leave the oven disconnected for at least 30 minutes to fully discharge internal circuits. Reconnect and test.
- Check for external interference: Avoid sharing the same outlet with high-noise devices (e.g., welders, large motors) that may cause surges.
- Surge protection: Consider using a surge-protected circuit or device to protect the oven electronics.
- PCB replacement: If E17 returns immediately after reset and the oven is unresponsive, the main control PCB (with firmware) must be replaced.
