Display shows H1; unit will not start ice production; fan may run but compressor stays off.

Safety: Move the unit only when it is unplugged and the water reservoir is secure.

Steps:

• 1. Measure room temperature: Ensure the ice maker is used in a room within the recommended range (typically 10–32°C). Move it to a cooler location if necessary.
• 2. Improve ventilation: Provide at least 10–15 cm clearance on all sides and above the unit. Do not enclose it in a cabinet while operating.
• 3. Avoid heat sources: Keep the Princess ice maker away from stoves, dishwashers, direct sunlight, and heating vents.
• 4. Reset after cooling: Turn the unit off and allow it to cool for 30 minutes, then restart. If H1 persists in a cool room, the ambient sensor may be faulty and require replacement.
