Possible Causes

How to Fix / Troubleshooting

Safety First: Unplug the microwave before any disassembly.

  • Hard reset: Disconnect power for 15–20 minutes to fully discharge the control board, then reconnect.
  • Check power quality: Ensure the unit is on a stable, properly grounded circuit. Use a surge protector if power issues are common.
  • Control replacement: If E7 persists, the main control board must be replaced, as the EEPROM is typically not serviceable separately.
