Freezer displays E5 and may not cool; compressor may not start or may shut down quickly.

Safety: Disconnect mains power. Work carefully around the compressor and high-voltage components.

• Access compressor compartment: Remove the rear lower service panel to expose the compressor and electrical box.
• Visual inspection: Look for burnt marks on the start relay, melted plastic, or a tripped overload protector.
• Check compressor terminals: Ensure all spade connectors are tight and not oxidized. Do not pull on wires; grip the connector body.
• Test start relay/PTC: Remove the relay from the compressor. Shake it gently; if it rattles excessively or smells burnt, it is likely faulty. Measure resistance according to the part specification if available.
• Test compressor windings: With the relay removed and power disconnected, measure resistance between the three compressor pins. You should see three finite resistances; any open circuit or direct short to ground indicates a bad compressor.
• Replace faulty start components: Install a new Teka-compatible start relay/PTC and overload protector if they test bad. Ensure correct orientation on the compressor pins.
• If compressor is seized or windings are faulty: The compressor must be replaced, which requires refrigerant handling equipment and should be done by a certified refrigeration technician.

Test: Refit the cover, restore power, and listen for the compressor starting smoothly. Monitor cabinet temperature and confirm that E5 does not return.
