Part: Freezer thermostat/temperature control

Inadequate water flow or low pressure

How to Identify: Small or hollow cubes often accompany low water flow; water line may be kinked or frozen; low house water pressure.

Part: Water inlet valve/water supply line

Clogged or old water filter reducing flow

How to Identify: Ice cubes small or hollow; reduced water flow to dispenser/ice maker; filter not changed in ≥6 months.

Part: Water filter

Ice buildup freezing the fill tube
