Both refrigerator and freezer are warm; compressor not running but interior lights work.

Safety first: Unplug the refrigerator before accessing the compressor. Sealed system work should be done only by certified technicians.

Steps:

• Access compressor: Remove the rear lower panel to expose the compressor and start components.
• Listen for clicking: If you previously heard repeated clicking every few minutes, the start device may be failing.
• Inspect start relay/overload: Remove the start device from the compressor terminals and shake it gently; if it rattles or smells burned, it is likely bad.
• Test compressor windings: With the start device removed and power off, measure resistance between the three compressor pins. You should see finite resistances and no continuity to ground. A shorted or open winding indicates a bad compressor.

Corrective action: Replace the compressor start relay/overload assembly if the compressor tests good but will not start. If the compressor windings are faulty, the compressor and sealed system must be replaced by a professional.
