Ice maker fill tube frozen (no water reaches the ice maker)

Water freezes in the tube that feeds the ice maker. Thaw it with warm air, then find the cause or it will come back. The usual causes are a valve that seeps between fills, low pressure (slow fills freeze), a freezer set too cold, or cold air blowing on the tube. Replacing the valve is the most common lasting fix.

Before you start

Unplug the unit and shut off the water before thawing.
Keep the hair dryer away from standing water and don't let meltwater drip on it.
Don't use sharp tools in the tube; a nicked tube refreezes and leaks.

Refrigerator ice maker making small, thin or hollow cubes

In a refrigerator ice maker this is almost always a water-supply problem: low pressure, a clogged or badly seated filter, a kinked line or a reverse-osmosis system starving the valve. Low fill means the mold or tray doesn't fill. On Whirlpool-style ice makers the last cavity, next to the thermostat, starves first and triggers an early harvest. Fix the supply before replacing parts.

Refrigerator ice maker freezes cubes but won't harvest

Rule out the simple stops first: the shutoff arm or bin sensor, the On/Off control and a warm freezer. Then force a harvest with the ice maker's own test (T-H jumper on Whirlpool modules, three arm presses on GE, the Test button on Samsung and LG). If the forced harvest works, the ice maker is fine and the trigger (thermostat/thermistor or temperature) is the issue. If it doesn't, the ice maker usually gets replaced.

Refrigerator ice maker making ice too slowly

Slow production is usually a temperature or water problem, not a bad ice maker. Check the freezer and the ice maker area against the brand's requirements, then the filter and supply. Remember that a new install takes about a day. On door ice rooms, frosted ducts or a weak ice fan are the next suspects.
