medium severity
Smeg models: Smeg retro refrigerators have condenser coils at the back of the unit. The compressor compartment is at the lower rear. The 50s Retro Style and Victoria ranges use standard refrigeration components underneath the distinctive styling — diagnosis proceeds the same as any rear-condenser fridge.
Common causes
- Compressor overheating due to dirty condenser coils
- Compressor start relay failing
- Compressor at end of life
Step-by-step fix
- Clean the condenser coils thoroughly.
- Allow the compressor to cool for 30 minutes, then restore power.
- Listen for the compressor start — a clicking sound that repeats every few minutes without the compressor running points to a failed start relay.
- Test the start relay (shake it — a loose rattle indicates failure).
