How to Fix / Troubleshooting
Safety: Disconnect power before accessing the control board.
Steps:
- Power reset: Turn off the breaker or unplug the unit for at least 15 minutes to fully discharge the board. Restore power and test.
- Check for surge damage: Inspect the indoor PCB for burnt components, bulging capacitors, or scorch marks. If present, the board must be replaced.
- Stable power: Ensure the unit is connected to a stable power source. Consider using a surge protector or voltage stabilizer if your supply is unstable.
- Board replacement: If E9 persists after reset and no wiring issues are found, replace the indoor main PCB with an Electrolux-approved part.
Firmware reprogramming, if required, should be done by an authorized service center.
