How to Fix / Troubleshooting

Safety first: Avoid storing highly perishable items until temperature stability is restored.

Monitor with thermometer: Place a thermometer inside and log temperature over 24 hours to confirm fluctuations.
Improve loading: Avoid blocking vents and leave space between items for air circulation.
Reduce door openings: Limit how often and how long the door is opened.
Check sensor and control: Test and replace the cabinet temperature sensor if readings are erratic. If fluctuations persist, the main control board may be mismanaging compressor cycles.

Persistent large swings (more than 5–7°C) despite good usage habits should be evaluated by a technician.

Freezer cools but temperature fluctuates widely, causing partial thawing and refreezing.
