Freezer shows E6 and may not cool; compressor may not start or may start and stop rapidly.

Danger: Work near the compressor involves mains voltage. Unplug the freezer and wait several minutes before touching components. If unsure, call a technician.

• Access compressor compartment: Remove the rear lower cover to expose the compressor and electrical box.
• Visual inspection: Check for burnt smells, melted plastic on the start relay, or discolored wiring.
• Check connections: Ensure the start device is firmly attached to the compressor pins and that all spade connectors are tight.
• Test start relay/PTC: Remove the relay from the compressor. Shake it gently; if it rattles or shows burn marks, it is likely faulty. Measure resistance according to Balay specifications if available.
• Replace start device: Install a new Balay compressor start relay / PTC device (and start capacitor if your model uses one). Match the part number to your exact model.
• Reassemble and test: Refit the rear cover, restore power, and listen for the compressor starting smoothly. Monitor for cooling and ensure the E6 code clears.

If the compressor still fails to start or trips the overload, the compressor itself may be mechanically seized or the main PCB may be faulty. This requires professional diagnosis and often specialized tools.
