E10 error; unit runs but produces very little or no ice, often accompanied by long cycle times.

Safety first: Unplug the ice maker. Refrigeration work involves high pressure and refrigerant handling; many steps require a licensed technician.

• Step 1 – Clean condenser coil: Use a soft brush and vacuum to remove dust and lint from the condenser coil on your Teendow ice maker. Ensure the rear and sides have proper ventilation.
• Step 2 – Check condenser fan: Confirm the condenser fan runs whenever the compressor is on. Replace the fan motor if it does not operate.
• Step 3 – Observe frost pattern: With power restored briefly, inspect the evaporator plate. A normal system will frost evenly. Frost only at the inlet or no frost at all suggests low charge or restriction.
• Step 4 – Look for oil stains: Oil residue on tubing or joints can indicate a refrigerant leak. Do not attempt to braze or recharge unless you are certified.
• Step 5 – Call a professional: If cleaning and airflow improvements do not resolve E10, contact a qualified refrigeration technician to check pressures, locate leaks, and recharge the system as needed.
