18. Memory Corruption

The fridge’s electronic memory may experience corruption during a power outage. This can lead to inaccurate settings and unexpected behaviors. Including blinking lights.

19. Sensor Calibration Disturbance

Power interruptions can disrupt the calibration of sensors. It causes them to provide incorrect readings. This may trigger safety measures. Such as blinking lights, to indicate potential issues.

20. Aging Electronics

Older fridges may have aging electronic components. That is more vulnerable to power disruptions.

The sudden power loss and restoration can hasten their deterioration. That leads to blinking lights.

Each fridge model may exhibit unique behaviors based on its design and features. To address the blinking light issue comprehensively, consider the specific details mentioned above. Apply the appropriate solutions based on the particular reason.
