Freezer displays E6 and may not cool; compressor does not start or starts briefly then stops.

Safety first: Unplug the freezer. The compressor area contains live mains components—only proceed if you are comfortable working with electrical parts. Do not open the sealed refrigeration system.

• Access compressor compartment: Remove the rear lower service panel to expose the compressor, start device, and wiring.
• Inspect wiring and connectors: Check for loose spade connectors, burnt terminals, or melted plastic on the compressor start relay/PTC and wiring harness. Reseat or replace damaged connectors.
• Test start relay/PTC: Disconnect the start device from the compressor and shake it gently; if it rattles excessively or shows burn marks, replace the compressor start relay/PTC. You can also measure resistance according to the part’s specifications.
• Check compressor windings: With the start device removed and power disconnected, measure resistance between compressor terminals (C, S, R). Values should be finite and not shorted to ground. If windings are open or shorted, the compressor is faulty.
• Reassemble and test: After replacing the start device, reconnect wiring, refit the rear panel, and restore power. Observe whether the compressor starts and E6 clears.

Important: If the compressor does not start even with a new start device, or if the inverter module is suspected, contact a professional. Compressor or inverter replacement requires specialist tools and handling.
