Cloudy Ice
Symptom
Ice cubes are hollow or have large holes in the center.
Hollow Ice Cubes
Symptom
Ice has a bad taste or odor, even though the ice maker appears to be working normally.
Contaminated Ice / Taste and Odor Issue
Symptom
Ice maker cycles on and off frequently without producing much ice.
Short Cycling
Symptom
Ice maker emits a burning smell or visible smoke during operation.
Electrical Overheating / Component Burnout
Symptom
Ice maker forms a large slab of ice that bridges across the bin instead of breaking into cubes.
Ice Bridging / Slab Not Breaking
Symptom
Ice maker is making loud grinding, squealing, or rattling noises during operation.
Abnormal Operating Noise
Symptom
Ice maker leaks water onto the floor from the front or bottom of the unit.
External Water Leak
Symptom
Ice maker not producing any ice at all; unit has power but bin remains empty.
No Ice Production
Symptom
Ice maker produces ice but then shuts off and will not restart until power is cycled.
Control Lockup / Software Hang
Symptom
Ice maker produces ice, but production is very slow and bin never fills to normal level.
Low Ice Production
Symptom
Ice maker runs but makes very small or thin ice cubes or slivers that melt quickly.
Thin Ice / Undersized Cube Formation
Symptom
Ice maker runs continuously and overfills the bin with ice, not shutting off when full.
Ice Level Control Failure
Symptom
Ice maker stops mid-cycle and restarts later, with long pauses and inconsistent operation.
Thermal Overload / Overheating Shutdown
Symptom
Ice maker trips the household circuit breaker when it starts or during operation.
Electrical Overload / Short Circuit
Symptom
Ice maker vibrates excessively or rattles the cabinetry during operation.
Excessive Vibration
Symptom
Ice maker will not power on; no lights or response from controls.
No Power / Dead Unit
Symptom
Ice melts quickly in the bin and clumps together.
Poor Ice Storage / Warm Bin
Symptom
Visible corrosion or rust on internal metal components and in the ice bin.
Corrosion / Rust Contamination
Symptom
Visible frost or ice buildup on the evaporator plate or nearby tubing.
Evaporator Frost / Ice Buildup
Symptom
Water accumulates inside the ice bin or under the evaporator instead of draining properly.
