Possible Causes

Weak compressor start relay/PTC, Failing compressor drawing excessive current, Undersized or failed start capacitor, Low mains voltage supply

How to Fix / Troubleshooting

Safety: Unplug the freezer before working near the compressor.

Steps to address clicking:

  • 1. Verify supply voltage: If possible, check that mains voltage is within normal range. Avoid using long extension leads.
  • 2. Inspect start relay and capacitor: Access the compressor compartment and check for heat damage or loose connections on the start device.
  • 3. Replace start components: Fit a new Caple‑specified start relay/PTC and capacitor. Ensure correct wiring.
  • 4. Test operation: Restore power and observe whether the compressor now runs continuously without repeated clicking.

When to call a technician: If the compressor still fails to start with new components, the compressor itself may be seized or internally damaged and will require professional replacement.
