DIY Solutions

Clear the defrost drain

Moderate 15–30 minutes
Tools Needed: warm water source (turkey baster or squeeze bottle), pipe cleaner or soft brush, cotton buds
  1. Unplug the refrigerator and remove food and drawers to access the drain hole at the back bottom of the fridge interior.
  2. Inspect and remove visible debris around the drain hole with a pipe cleaner or cotton bud.
  3. Use warm (not boiling) water in a turkey baster to flush the drain until it flows freely.
  4. Dry excess water and replace drawers and contents; plug refrigerator back in and monitor for recurrence.
⚠️ Safety First: Always unplug the appliance before accessing internal components to avoid electrical hazards.

Level the refrigerator

Easy 10–15 minutes
Tools Needed: spirit level, wrench or adjustable feet
  1. Place a spirit level inside the fridge on a shelf to check if it’s level side-to-side and front-to-back.
  2. Adjust the leveling feet underneath the fridge as needed until it is level.
  3. Check that water now flows toward the drain during normal operation.
⚠️ Safety First: Ensure stability after adjustments to prevent tipping.

Inspect and clean door gasket

Tools Needed: warm soapy water, cloth
  1. Inspect the door gasket for visible damage, gaps, or dirt.
