E5 appears on the display, freezer may not start cooling or may shut down unexpectedly.

Critical safety: Work on compressor electrics only with the appliance unplugged. Do not attempt sealed system repairs without proper certification.

Basic checks:

• 1. Ventilation and condenser: Ensure the freezer has adequate space around it and that the rear condenser is clean. Overheating can trigger overload protection and cause E5.
• 2. Access compressor components: Remove the lower rear service panel to expose the compressor, start relay/PTC, overload protector, and wiring.
• 3. Inspect start relay and overload: Look for burn marks, melted plastic, or a rattling sound when you shake the relay (a sign of internal damage).
• 4. Replace start device: If the relay or PTC looks damaged, replace it with an "Amica Compressor Start Relay/PTC" matched to your compressor model. Also replace the overload protector if discolored or cracked.
• 5. Capacitor check (if present): Some models use a start or run capacitor. If bulged or leaking, replace with the same µF rating and voltage.
• 6. Test run: Reassemble, restore power, and listen. If the compressor hums briefly then clicks off repeatedly, the compressor itself may be mechanically seized and require professional replacement.

When to call a technician: If new start components do not resolve E5, the compressor or main control board is likely faulty and should be handled by a refrigeration specialist.
