# LG ice fill tube and heater service

### Small hollow cubes, then a slab in the bin

The order this happens in is worth knowing, because it lets you catch it early. First the cubes come out undersized and hollow, because the tray is being filled with whatever got past the ice at the mouth of the tube. Then water spills over and freezes into the slab that welds the tray to the bin below it. Then the fill stops altogether and no code appears anywhere, because nothing about this is measured. Clearing it with warm water buys you weeks. If it has come back twice, the heater wrapped around that tube has stopped doing its job and the visit is about the heater rather than the ice.

What this involves

The commonest no-ice cause that no code reports

Clearing it is quick; the heater around it is the real repair

Often paired with a door that is not sealing

Confirm water is arriving

The dispenser first. If that is fine, the supply is fine.

Thaw the tube

A warm damp cloth rather than boiling water into a plastic housing.

Find out why it froze

A door held ajar, a failing gasket, or a fan that has stopped feeding the compartment. The ice is the symptom.

Test the fill tube heater

Where the model has one. It is what keeps the mouth clear and it fails silently.

Verify a full harvest cycle

Water in, freeze, eject. Anything less is guessing.

### Can I melt it myself?

Warm water from a turkey baster, patiently, with the machine unplugged and a towel underneath. No hair dryer and nothing sharp — the tube is plastic and the tray around it is thinner than it looks.

### Why does it keep happening in one house and never in another?

Door openings and humidity. A freezer opened twenty times an evening in August takes in air that condenses on the coldest thing it can find, and the mouth of that tube is often it.
