# LG ice makers

### Where the ice actually is

On this make it is inside the refrigerator. LG’s US catalog has no undercounter ice machine in it — the only ice-maker products it lists are automatic ice maker kits, the retrofit part for a cabinet that was built to take one and shipped without. So an ice call on an LG is a refrigerator call, and it is answered with the refrigerator’s own diagnostics.

### Three codes, and what they rule out

LG names the ice maker fan IF, the ice maker temperature sensor IS and the ice maker motor It. Between them they cover air, cold and mechanism, which is most of what can go wrong once water has arrived. What no code covers is the water getting there in the first place — a fill tube frozen at the mouth, a filter cartridge with air behind it, or a supply line crimped when the cabinet was pushed back — and in a South Florida kitchen that is the larger half of the calls.

Where the ice actually is

On this make it is inside the refrigerator. LG’s US catalog has no undercounter ice machine in it — the only ice-maker products it lists are automatic ice maker kits, the retrofit part for a cabinet that was built to take one and shipped without. So an ice call on an LG is a refrigerator call, and it is answered with the refrigerator’s own diagnostics.

Three codes, and what they rule out

LG names the ice maker fan IF, the ice maker temperature sensor IS and the ice maker motor It. Between them they cover air, cold and mechanism, which is most of what can go wrong once water has arrived. What no code covers is the water getting there in the first place — a fill tube frozen at the mouth, a filter cartridge with air behind it, or a supply line crimped when the cabinet was pushed back — and in a South Florida kitchen that is the larger half of the calls.

### No ice at all, but the water dispenser still works. What does that narrow it to?

It rules out the supply and the valve inlet, because both feed the same line, and it moves the question inside the compartment. That leaves the fill tube — which freezes at the mouth in this climate and blocks the water before it reaches the tray — the ice maker's own motor, which LG codes as It, or the air getting to it, which is IF. The order matters: a warm cloth on the fill tube answers the question in ten minutes and costs nothing.

### It made ice and then stopped after I changed the filter.

Common, and usually not a failure. A new cartridge puts air into the line, and the machine will not fill a tray it cannot fill cleanly. Run four or five liters through the water dispenser until it stops spitting, check the cartridge is seated to the stop, and give it a day. If there is still nothing after twenty-four hours, and no code, then it is worth a visit.

### The cubes are hollow, or they taste of the freezer.

Hollow cubes are a fill problem — the tray is being filled short, which is pressure, a partly blocked line or a valve that is not opening fully. Taste is almost always the bucket rather than the water: ice takes on whatever the compartment smells of, and a bucket that has been sitting through a slow summer will do it every time. Empty it, wash it, and give it a fortnight.
