When the freezer door on the left side of an LG French-door fridge fails to seal properly, cold air leaks in, frost builds up, energy is wasted, and food may spoil faster. There are several reasons this can happen:
- Dirty, warped, or damaged gasket
The gasket (the rubber seal around door’s perimeter) may be dirty, deformed, torn or hardened. Dirt or food residue can prevent the seal from making full contact. Over time, the gasket can lose flexibility or get damaged. - Misalignment or leveling issues
French-door fridges need to be properly leveled. If the appliance is tilted, or the hinges are loose, the door may sag or not close flush, especially the left side. The hinge might need adjustment. - Obstructions inside freezer/freezer drawer or door
A shelf, bin, or container might be sticking out and preventing the door from closing fully. Even ice/frost buildup can act as an obstruction. - Frozen condensation, frost accumulation
Moisture that condenses around the seal or edges can freeze and block seal contact. This often happens more on one side. - Magnetic strip weak or loose seal
The door gasket often has a magnetic bead that helps pull and hold the door closed. If that magnet loses strength or the gasket loosens from its mounting channel, sealing fails. - Wear & age
If the fridge has been used for many years, the materials degrade (gasket, hinges), making problems more likely.
How to Diagnose It
Here are practical steps to figure out exactly what’s wrong:
| Diagnostic Step | What to Look For / Do |
|---|---|
| Visual inspection | Open the freezer, examine the left gasket for tears, cracks, deformation, or built-up grime. Check if it sits evenly in its groove. |
| Paper test | Close the door on a strip of paper along various points on the left side. If the paper pulls out easily, that represents a gap in the seal. |
| Check alignment / leveling | Use a spirit level across top and side of fridge. Check whether the left door sags or whether hinges are loose. Also ensure the cabinet is level on the floor. |
| Obstruction check | Remove or rearrange bins, shelf items, or ice build up to see if something is preventing the door from closing fully. |
| Frost / condensation check | Look for frost forming unevenly, especially around left side, since leaking warm air causes frost near gaps. |
| Magnet/gasket test | Is the gasket flexible? Does the magnetic pull feel weak? A weak magnetic strip or gasket that does not return snugly may need replacing. |
What You Can Do: DIY Fixes
Here are several corrective actions you can try before calling a professional:
- Clean the gasket
Use warm water and mild detergent; scrub gently, rinse, and dry thoroughly. Remove any debris or sticky substances. - Re-seat or adjust gasket
If the gasket has come loose, you can try pushing it back into its mounting channel (“track”) around the door. Using a little petroleum jelly can help it slide in more easily and improve sealing. - Adjust or tighten hinges / level appliance
Tighten any loose hinge bolts; adjust leveling feet in front and/or back so the fridge is even. This may help the left door close flush. - Defrost / remove frost build-up
If frost or ice is jammed near the left seal, turn off the freezer or let it defrost; remove the ice carefully then dry the area. Ice prevents proper sealing. - Replace the gasket
If cleaning and adjustment don’t help, a new OEM gasket may be required. Buying the correct model part is very important. Removal and installation often involve pulling out the old gasket, cleaning the groove, aligning the new one, starting at a top corner, pressing it into place, and ensuring there are no gaps. - Temporary fixes
Sometimes applying a bit of petroleum jelly or gasket conditioner helps the seal adhere better. Or gently heating the gasket (e.g. with a hair-dryer for a short time, low heat) to help reshape it (if warped). Use caution.
When to Call a Professional Repair Service
If after trying the above you still have leakage on the left side, or if the issue is complicated (warped door, severely damaged gasket, hinge frame bent), it’s time to call an appliance repair expert. Here’s when professional help makes sense:
- The gasket is torn, cracked, or missing in places beyond simple repair.
- Door hinges are bent, broken or require parts replacement (hinge pins, cams).
- Door frame or cabinet is warped.
- Seal problems persist despite cleaning & adjustment (especially if energy bills spike or food safety is affected).
- You don’t feel comfortable doing the repair yourself (e.g. handling tools, risk of damage).

Tips to Prevent Left-Side Seal Problems in the Future
- Clean the gasket regularly (every few weeks) to prevent dirt build-up.
- Avoid overloading freezer shelves, bins, or placing heavy items near the hinge side, which can stress the door.
- Maintain good internal temperature; avoid putting in large amounts of hot food that can cause condensation.
- Check and level the fridge especially after moving it or after floor settling.
- Inspect seals periodically for wear and damage, and replace before they fail completely.
Summary
If your LG French-door freezer isn’t sealing on the left side, the problem could be a dirty or damaged gasket, misalignment, leveling issues, frost build-up or a weak magnetic strip. Many times you can fix it yourself by cleaning the seal, reseating or replacing the gasket, adjusting hinges, or defrosting. But if these DIY steps don’t work, or there’s physical damage, it’s best to call a professional like Express Repair NY for fridge repair or LG appliance repair to address the issue properly and ensure lasting results.
