Refrigerator not cooling at all, both fresh food and freezer sections warm, interior lights work but no cooling.

Safety first: Unplug the refrigerator. Sealed system and high-voltage work should be done carefully.

Basic checks:

• Confirm the outlet has power by plugging in another appliance.
• Listen for any humming or clicking from the compressor area when the unit is plugged in.

Compressor compartment inspection:

• Remove the rear lower access panel.
• Check the compressor start relay/overload device for burn marks or a burnt smell.
• Shake the relay gently; if it rattles, it is likely bad.

Repair: Replace the compressor start relay/overload with a Summit-compatible part. If the compressor still does not start or draws very high current and overheats, the compressor or main control board may be defective and should be diagnosed by a professional.
