Freezer not cooling at all; interior is room temperature, but lights may still work.

Safety: Unplug the freezer before accessing the compressor compartment. High voltage is present when powered.

Steps:

• Confirm symptoms: Listen for any humming or clicking from the compressor area when the unit is plugged in. If silent, proceed.
• Check outlet: Test the wall outlet with another appliance to ensure it has power.
• Access compressor components: Remove the rear lower panel to expose the compressor, start relay, and capacitor.
• Inspect relay and capacitor: Look for burn marks, melted plastic, or a swollen capacitor. Replace the compressor start relay and/or start capacitor if damaged.
• Check wiring: Verify that the harness from the main control board to the compressor is intact and firmly connected.
• Control board test: If the relay and capacitor are good but the compressor never receives power, the main control board may be defective and should be replaced by a professional.
• Compressor failure: If the compressor hums briefly then clicks off repeatedly even with new start components, the compressor itself may be locked or failed, requiring a sealed-system repair.
