The freezer interior temperature fluctuates widely; some items freeze solid while others remain soft.

Safety first: Unplug the freezer before removing any panels.

Step-by-step checks:

• 1. Reorganize contents: Keep vents and fan outlets clear. Do not pack food tightly against the rear wall.
• 2. Check fan operation: Verify that the evaporator fan runs whenever the compressor is on. Replace the fan motor if it operates intermittently.
• 3. Inspect for frost: Remove the inner rear panel and check for ice blocking the coil or ducts. Resolve any defrost issues.
