Ice maker shows refrigerant system error, very low or no ice production

Safety first: Do not attempt sealed system repairs unless properly certified. High pressures and refrigerant handling require special tools and training.

• Basic checks: Ensure condenser coil is clean and fans are operating. Poor airflow can mimic sealed system issues.
• Observe frost pattern: With panels removed, a very small frost pattern on the evaporator or none at all can indicate low charge or restriction.
• Listen for compressor: Confirm the compressor runs continuously but ice production remains very low.
• Call a technician: If basic airflow and electrical checks are normal, contact an EPA-certified refrigeration technician to check pressures, locate leaks, and repair the sealed system.
