E19 displayed, unit reports high ambient temperature or overheat condition and shuts down

Safety: Allow the unit to cool before servicing. Do not operate the ice maker in environments outside the specified temperature range.

• 1. Check room temperature: Verify the ambient temperature is within Iceman’s specified range (often 50–100°F / 10–38°C). Relocate the unit if necessary.
• 2. Clear airflow paths: Ensure nothing is blocking the front, sides, or rear vents. Move the unit away from walls or heat sources.
• 3. Clean condenser and fan: Remove dust from the condenser coil and fan blades to improve cooling efficiency.
• 4. Inspect overheat thermostat: Some models use a manual-reset high-limit thermostat. Locate it on the compressor or condenser area and press the reset button if present. Test for continuity and replace if it trips prematurely.
• 5. Check ambient thermistor: Measure its resistance and compare to spec. Replace if reading is significantly lower than expected (indicating falsely high temperature).
