Possible Causes

Failed compressor start relay/PTC, Faulty compressor overload protector, Open compressor winding, Defective main PCB compressor relay

How to Fix / Troubleshooting

Safety first: Unplug the refrigerator before removing the rear service panel. High voltages are present when powered.

  • Step 1 – Listen for clicking: When first plugged in, repeated clicking from the compressor area without sustained running suggests a start device issue.
  • Step 2 – Access compressor: Remove the rear lower cover. Take off the plastic terminal cover on the compressor.
  • Step 3 – Inspect start device: Check the PTC relay and overload for burn marks or cracks. Gently shake the PTC; if it rattles, it is likely faulty.
  • Step 4 – Replace start components: Fit a new SMEG-specified start relay/PTC and overload protector, matching the compressor model.
  • Step 5 – Test: Refit covers, restore power, and observe. If the compressor still fails to start, the compressor itself or main PCB may be defective, requiring professional sealed-system service.
