How to Fix / Troubleshooting
Safety: Unplug the appliance before accessing the control board.
Steps:
- 1. Power cycle: Disconnect power for 15 minutes and reconnect. If E19 returns immediately, suspect the board.
- 2. Inspect environment: Check for signs of water leaks above or behind the freezer that could drip onto the control board area.
- 3. Visual inspection: Remove the rear panel and examine the main PCB for burnt spots, cracked components, or insect nests.
- 4. Replace main PCB: If damage is visible or E19 persists, replace the "Amica Main Control Board" with the correct part number.
Note: Board-level repair is not recommended for most users; replacement is the standard remedy.
