LG refrigerator not cooling and clicking

Repeated clicking can involve start attempts, fans or controls and should be assessed with temperature and airflow evidence.

What this evidence points to

Check temperatures and airflow before moving toward compressor or refrigerant work.

LG uses model-specific support pages and several appliance error-code families. Confirm the complete suffix when possible.

Model check: Usually printed on a label around the door opening, rear panel or inside wall. Official LG support →

What FixEvidence outcomes show

Outcome data is still growing

We do not publish a success percentage until there are at least five relevant attempts. Official guidance remains clearly separate from user outcomes.

Is another repair worth it?

Compare age, money already spent, next repair cost and replacement price.

Frequently asked questions

Should I replace a part based only on an error code?

No. An error code identifies a detected condition, not always the failed component. Rule out safe, inexpensive causes and confirm against the exact model.

Why does FixEvidence ask what I already tried?

Because the best next action changes when earlier checks have failed. Removing repeated advice is central to the ranking engine.

Are FixEvidence success rates verified?

Every percentage displays its number of attempts and confidence. Model photos, receipts, invoices, technicians and completed follow-ups are tracked as separate evidence signals.
