Does the water dispenser still work?
That one check splits ice maker trouble in half. New York Appliance Desk books ice maker repair across Manhattan, Brooklyn, Queens and the Bronx for refrigerator ice makers (in the freezer or in the door) and for standalone undercounter machines.
If water pours normally from the door, the water line, the shutoff and most of the inlet valve are doing their job. The fault is further along: the fill tube that feeds the ice mold, the mold's heater, the module that runs the harvest cycle, or the arm or sensor that tells it the bin is full. If neither water nor ice comes out, the tech starts at the supply instead: the saddle valve or shutoff behind the fridge, a kinked line, the filter and the inlet valve.
Which fault fits what you're seeing?
| What you see | Usual cause |
|---|---|
| No ice, water works | Frozen fill tube, failed module, bin-full arm stuck up, freezer too warm |
| No ice and no water | Shutoff closed, kinked line, clogged filter, failed inlet valve |
| Small or hollow cubes | Low fill: filter, valve, low water pressure |
| Ice clumped in the bin | Freezer temperature swinging, or a door ice room fan failing |
| Water on the floor under the dispenser | Cracked fill line, a leaking inlet valve, or the door ice chute frozen open |
Samsung code 39E or 40E | Ice maker function or ice room fan, by Samsung's code list |
Is hard water clogging it?
Rarely, in the five boroughs. New York City's water averages about 2 grains of hardness per gallon, soft by any measure, so the mineral crust that clogs inlet screens in other cities is uncommon here. When a New York ice maker slows down, the filter and the fill tube are the likelier culprits. An overdue filter cuts flow before it does anything else.
French-door fridges with ice in the door
Many French-door models from Samsung, LG and others make ice in a small insulated compartment in the left door, cooled by a fan that pulls freezer air up through a duct. When that fan or its duct ices over, the ice maker slows or stops while the freezer below stays cold. Frost around the ice room door, or clumped ice, points here. See the Samsung and LG pages for their ice codes.
