Clicking noise every few minutes, compressor attempts to start but shuts off quickly; unit not cooling.

Safety first: Unplug the refrigerator before touching any electrical components. High voltage and hot surfaces are present.

Step 1 – Verify adequate power

• Ensure the refrigerator is on a dedicated circuit with proper voltage (typically 120V).
• Avoid extension cords or power strips.

Step 2 – Inspect start relay/overload

• Access the compressor and remove the start relay/overload from the compressor terminals.
• Shake the relay gently; if it rattles or smells burnt, replace it.

Step 3 – Test compressor windings

• With power off, measure resistance between compressor terminals; if windings are open or shorted, the compressor is failed.

Step 4 – Replace start components

• Install a new OEM Sub‑Zero start relay/overload and reassemble.
• Restore power and monitor for normal compressor start.

When to call a professional: If the compressor still fails to start or overheats, a sealed system technician is required.
