Freezer temperature swings widely — Inconsistent cooling

What does Freezer temp swings mean?

The freezer temperature fluctuates significantly throughout the day (e.g., from 9F to +9F and back), moving far from the set temperature, even though no error codes are displayed. The Refrigerator section is more stable.

• Faulty defrost cycle causing temporary temperature changes
• Failing thermistor (temperature sensor) providing inaccurate readings
• Main control board issue affecting temperature regulation
• Weak compressor struggling to maintain consistent temperature

1. 1

   Ensure the freezer door is sealing correctly and not being opened excessively or left ajar.

2. 2

   Check for any obstructions around the air vents inside the freezer that might impede cold air circulation.

3. 3

   Unplug the Refrigerator for a few hours to allow any internal ice buildup to melt, then plug it back in.

4. 4

   If the problem persists, it may indicate a need to check the thermistor or the main control board, which might require a technician.
