Refrigerator displays EC60; may be associated with high temperature alarms or compressor not running as expected.

Safety first: This fault involves high‑voltage and sealed system components. Do not attempt sealed system repairs without proper certification. Always disconnect power before inspection.

Step 1 – Listen and feel for compressor operation

• With the unit powered, listen at the rear for compressor humming or vibration.
• If the compressor is silent and cool while the unit is calling for cooling, there may be an inverter or control issue.

Step 2 – Inspect wiring and inverter module

• Unplug the unit and remove the rear access panel.
• Visually inspect the compressor inverter board and wiring harness for burn marks, loose connectors, or damaged insulation.
• Reseat all connectors firmly.

Step 3 – Basic electrical checks (for qualified users)

• With power off, check continuity of the compressor windings at the inverter output terminals. All three windings should have similar resistance; an open winding indicates a failed compressor.
• If the compressor windings test good but the inverter shows signs of damage or does not attempt to start the compressor, the inverter board may be faulty.

Step 4 – Power cycle and monitor

• Restore power and allow the unit to attempt a start. If EC60 reappears quickly and the compressor never starts, further diagnosis by a professional is required.

When to call a professional: EC60 almost always requires a Sub‑Zero authorized technician. They can test the inverter, compressor, and control board under load and perform sealed system work if needed.
