Ice maker runs but produces no ice at all; compressor and fan may or may not run.

Safety first: Unplug the unit before inspection. Do not attempt to cut or open refrigerant lines; this requires certified service.

Diagnostic steps:

• Check for basic operation: Plug in and start a cycle. Listen for the compressor humming and feel for vibration. Check if the condenser fan is spinning and if warm air is blowing from the rear vents.
• Feel the evaporator: After 10–15 minutes of run time, carefully touch the evaporator plate (with dry hands). It should be very cold and may start to frost. If it remains at room temperature, cooling is not occurring.
• Inspect condenser fan: If the compressor is hot but the fan is not running, unplug the unit and inspect/replace the condenser fan motor.
• Check for oily residue: Look around refrigerant joints and the evaporator for oily spots, which can indicate a refrigerant leak.
• When to call a professional: If the compressor runs but there is no cooling, or if you suspect a refrigerant leak or blocked capillary, contact a certified refrigeration technician. These repairs require specialized tools and recharging the system.
