E5 displayed and compressor may not start or may run continuously without proper cooling.

Critical safety: Mains voltage and compressor terminals are hazardous. Unplug the freezer before removing the rear service panel. If you are not experienced with electrical testing, contact a professional.

Steps:

• 1. Access compressor compartment: Remove the lower rear cover to expose the compressor, start device, and wiring.
• 2. Visual inspection: Look for burnt marks on the start relay/PTC module and overload protector. Check for melted connectors or a burnt smell.
• 3. Check connections: Ensure all spade connectors are firmly seated on the compressor terminals (C, S, R). Tighten any loose connections.
• 4. Test start device: Remove the start relay/PTC and shake gently; if it rattles excessively or shows signs of burning, replace it with a compatible Belling compressor start device.
• 5. Overload protector: Test for continuity when cool. If open and not resetting, replace the overload protector.
• 6. Compressor test: Measure resistance between compressor terminals. If windings are shorted to earth or readings are abnormal, the compressor is likely faulty and requires specialist replacement.

Warning: Do not bypass safety devices (overload or relay). This can cause fire or compressor damage.
