Wine cooler shows E5 and may not maintain set temperature; compressor operation seems abnormal.

Safety: Unplug the unit before accessing the rear service panel. Do not attempt sealed system repairs without proper certification.

• Access compressor compartment: Remove the rear lower panel to expose the compressor, start device, and main PCB/inverter module.
• Check ventilation: Ensure the condenser area is clean and that there is adequate space around the cooler. Overheating can trigger E5.
• Inspect start device: Remove the start relay/PTC from the compressor terminals. Shake it gently; if it rattles or shows burn marks, replace it with a compatible Blomberg start device.
• Test overload protector: With a multimeter, check continuity across the overload. If open when cool, replace the overload.
• Inverter models: If your Blomberg wine cooler uses an inverter compressor, visually inspect the inverter board for burnt components. Inverter diagnosis and replacement should be done by a professional.
• If E5 persists: The compressor itself may be drawing excessive current or be mechanically locked. This requires sealed system service by an authorized technician.
