What Does Error E05 Mean?

The Smeg Refrigerator error E05 indicates a fault in the compressor start/run circuit, leading to intermittent cooling and erratic temperature fluctuations. This error may cause the display to show E05 while the unit fails to maintain a consistent temperature. Addressing this issue often requires diagnosing and potentially replacing components like the compressor start relay or run capacitor.

Common Symptoms:

  • Refrigerator stops cooling intermittently
  • Unit cycles erratically or fails to maintain temperature
  • Error code E05/E5 shown on display

Possible Causes

  • Compressor start/run circuit fault (medium)

How to Fix Error E05

DIY Fix Basic checks before calling a technician

  1. Ensure the refrigerator is plugged in and receiving power.
  2. Check for unusual sounds from the compressor area (e.g., clicking without running).
  3. Note if cooling is intermittent or the error persists after a brief power cycle.

Technician Only Diagnose and repair compressor start/run circuit

  1. Disconnect power and remove rear service panel to access compressor area.
  2. Inspect the compressor start relay/PTC device and run capacitor (if present) for signs of damage (burn marks, melted plastic) or failure.
  3. Check wiring at compressor terminals and ensure all connectors are tight and free of corrosion.
  4. Replace faulty start relay/PTC device or run capacitor with appropriate SMEG‑specified parts.
  5. If replacing start components does not clear the error, test the compressor and main control board for deeper faults.

Parts needed: Compressor start relay/PTC, Run capacitor (if fitted), Wiring/connectors

🛑 When to Call a Pro:
  • If error code persists after basic user‑level checks
  • If there are burning smells, loud unusual noises, or overheating near the compressor
  • If you are not trained in electrical/compressor diagnostics
