Common Causes

The hardest water in the Bay Area

Contra Costa Water District delivers around 7.2 grains per gallon in Concord, several times EBMUD's supply, and a valve held off its seat by deposit weeps continuously.

A clogged defrost drain

Melted frost backs up and overflows into the cabinet or onto the floor instead of draining away normally.

A worn or torn door gasket

Lets humid air in that condenses inside the cabinet or around the door frame.

Local conditions that matter here

Concord averages 88.0°F in July. Oakland, twenty miles west through the Caldecott, averages 71.6°F, and the annual swing out here is 30.4°F against 13.9°F there. A condenser in a garage on this side of the tunnel works in air the bay side never sees, runs long, runs hot and fails early — and the wine room behind that garage wall is doing the same work.

What You Can Check Yourself

Check for visible ice or debris blocking the defrost drain opening
Inspect the door gasket for gaps, tears, or debris preventing a full seal

Common Questions About Freezer Leaking

Can I keep using my LG appliance while this happens?
If it's still working normally otherwise, short-term use usually isn't harmful — but a persistent issue means something is actively failing, and continuing to run the unit can turn a smaller repair into a larger one. We'd recommend having it looked at within a few days rather than waiting until it fails entirely.
Will freezer leaking go away on its own?
Occasionally a one-off glitch clears itself after a power cycle, but if it's a specific component wearing out, it will keep coming back and typically gets worse over time rather than resolving on its own.
How much does this repair typically cost?
It depends on which component is at fault. We charge a flat diagnostic fee and provide a firm quote before any repair work begins — see our repair pricing page for typical ranges.
How long does a typical repair visit take?
Most single-component repairs are completed in one visit, often within an hour or two once the part is confirmed. We'll give you a specific estimate after diagnosis.
Do you offer a warranty on the repair?
Yes — every repair includes a written warranty of up to 1 year on parts and labor.
Do you service LG appliances in my area?
Likely yes — we cover Walnut Creek and 24 surrounding communities. See our full service area list to confirm.
