Evidence-based refrigerator diagnosis

Refrigerator not cooling

Check food safety, settings, airflow, doors, and installation before service.

Stop immediately for smoke, burning odor, sparking, gas odor, a melted plug, or water near electrical parts.

Before you begin

Choose the exact appliance model

Select a verified model when available. If yours is not listed, you can use general checks, but model-specific teardown instructions stay locked.

After the guided checks

Repair, claim warranty, or replace?

This transparent heuristic starts only after safe checks and a real repair estimate. It never identifies a failed part.

Published rule: warranty coverage wins first. Otherwise the tool compares repair cost with delivered replacement cost, then uses age and repeat failure only as tie-breakers. It does not include energy savings, financing, sentimental value, or local disposal incentives.

Parts note

No internal part is recommended from a symptom alone. Confirm the full model and a real component diagnosis before ordering.
