On hot summer days the fridge works harder to reject heat. A few simple habits help a lot and prevent weak cooling that people mistake for a fault.
Practical tips
- Leave ventilation space behind and beside the fridge per the installation guide.
- Keep it away from the oven and direct sun.
- Clean dust around the condenser after unplugging.
- Never put hot food straight in.
- Don't overfill so that vents are blocked.
- Check the gaskets.
- Keep door openings short.
- Use recommended settings (about 3° fridge, −18° freezer per LG).
When it's a fault
If codes like CF, FF or FU appear, the compressor doesn't run, or the freezer won't freeze despite these tips.
FAQ
Should I max out cooling in summer?
Not necessarily; recommended settings are usually enough with good ventilation.
Is louder operation in summer normal?
Usually yes, as the compressor and fans work more.
