Possible Causes
Compressor drawing excessive current due to internal mechanical fault, Shorted compressor windings, Incorrect mains voltage, Faulty current-sensing circuit on main PCB
How to Fix / Troubleshooting
Safety: This involves high voltage and potentially sealed system issues. Exercise caution and consider professional service.
Checks:
- 1. Ventilation: Ensure the condenser is clean and the freezer has adequate clearance. Overheating can increase compressor current.
- 2. Listen and feel: When powered, if the compressor attempts to start then quickly stops with a click, overcurrent protection may be tripping.
- 3. Basic electrical test (advanced): With power disconnected, remove the compressor start device and measure resistance between compressor terminals. Very low resistance or a short to ground indicates a failed compressor.
- 4. Replace start components: If windings test normal, try replacing the "Amica Compressor Start Relay/PTC" and overload protector.
- 5. Professional help: If E18 persists, the compressor or main PCB current-sensing circuit is likely faulty. Compressor replacement requires a certified refrigeration technician.
Warning: Do not repeatedly reset and force the compressor to start; this can cause further damage.
