Freezer temperature fluctuates widely; some days too warm, other days too cold.

Safety: Unplug the freezer before accessing internal controls or sensors.

Steps to stabilize temperature:

• Check loading: Avoid blocking air vents with large packages. Distribute food evenly to allow air circulation.
• Monitor with thermometer: Place an appliance thermometer inside and record temperatures over several days to confirm fluctuations.
• Inspect sensor/thermostat: Ensure the sensor is properly mounted and not touching the evaporator directly. Replace if readings are erratic.
• Control board: If mechanical parts are good but temperature swings persist, the control board may be intermittently failing and should be replaced.

Note: Some variation is normal during defrost cycles, but large swings indicate a control issue.
