Microwave shows E06 and may run the fan or light unexpectedly; cooking functions are disabled.

Safety: Unplug the microwave before inspection.

Try this first:

• 1. Hard reset: Unplug for at least 10 minutes to fully discharge internal logic circuits. Plug back in and test.
• 2. Check power quality: Avoid using long extension cords or sharing the outlet with high-draw appliances. Plug directly into a properly grounded outlet.
• 3. Visual inspection: Remove the outer cover (if you are comfortable and after unplugging). Inspect the control board area for burn marks, swollen components, or loose connectors on the low-voltage harness.

Next steps: If E06 returns, the main control PCB is likely faulty. Replacement requires transferring wiring connectors exactly as found. If you are not experienced with electronics, have a technician replace and program the board.
