How to Fix / Troubleshooting

Safety: Unplug the freezer before accessing internal components.

Steps:

Verify power stability: Ensure the freezer is on a dedicated circuit without frequent outages or brownouts.
Check fan operation: Listen for the evaporator fan cycling normally when the compressor runs. Replace the fan motor if it stops randomly.
Inspect thermistor and wiring: Check for loose connections or damaged wires. Test the thermistor and replace if readings are unstable.
Control board: If sensors and fans are good, an intermittent main control board may be causing erratic cycling and should be replaced.

Tip: Use a separate thermometer to confirm fluctuations before replacing parts.

Freezer temperature fluctuates widely; items partially thaw then refreeze
