Possible Causes
Failed Wi‑Fi module, Loose communication harness, Firmware mismatch, Main control communication port failure
How to Fix / Troubleshooting
Safety First: Disconnect power before accessing electronic modules.
- Power cycle: Turn off the breaker for 5 minutes, then restore power and check if E6 clears.
- Check Wi‑Fi module: Locate the Wi‑Fi / communication module (often near the control board). Ensure its harness is fully seated.
- Inspect harness: Look for pinched or damaged low-voltage wires between the main control and Wi‑Fi module. Repair or replace as needed.
- Firmware update: If the oven still operates but shows E6, check Insignia support for any firmware updates or reset procedures for smart models.
- Module replacement: Replace the Wi‑Fi module first; if E6 persists, the main control board’s communication circuit may be defective and require replacement.
