Safety: Basic checks are non-electrical; unplug the unit before removing rear panels.

Steps to address Hi:

Ensure door is closed: Check for items preventing full closure. Inspect the gasket for tears or warping.
Check airflow inside: Make sure bottles are not blocking internal air vents at the back or sides.
Clean condenser: Unplug the cooler, pull it away from the wall, and vacuum dust from the rear grille and condenser coils.
Verify condenser fan operation: With the unit plugged in and calling for cooling, confirm the fan near the compressor is running. If not, the fan motor may be bad.
Monitor temperature: After cleaning and ensuring proper airflow, allow 12–24 hours for temperature to recover. Use a thermometer to verify.

Call a technician if the compressor runs continuously but the cabinet does not cool, as this suggests a sealed-system problem.
