Check the Power: Make sure the refrigerator is plugged in and receiving power. Sometimes, a loose plug or a tripped circuit breaker can be the cause of the issue.

Temperature Settings: Ensure that the temperature settings for both the refrigerator and freezer compartments are set appropriately. The recommended temperature for the fridge is around 37-40°F (2-4°C), and for the freezer, it's around 0°F (-18°C).

Condenser Coils: The condenser coils at the back or underneath the refrigerator can accumulate dust and debris over time, causing reduced cooling efficiency. Clean them regularly to improve performance.

Door Seals: Check the door seals for any cracks or gaps. A faulty seal can lead to warm air entering the fridge, causing it to work harder and consume more energy. Replace seals if necessary.

Condenser Fan: The condenser fan, located near the compressor, helps dissipate heat. If it's not working properly, the refrigerator might not cool effectively. Check for obstructions or damage.
