Display shows H1 and ice production is suspended; unit may still power on.

Safety: Do not attempt to bypass temperature protections; this can damage the compressor.

Steps:

• Check room temperature: Measure ambient temperature where the SMAD ice maker is installed. If above 32°C (or the specified limit in your manual), relocate the unit to a cooler area.
• Improve ventilation: Ensure at least 10–15 cm clearance on all sides and the back. Remove any objects blocking the air intake or exhaust grilles.
• Away from heat sources: Move the unit away from ovens, dishwashers, radiators, or direct sunlight.
• Reset: After the unit has cooled to normal ambient temperature, unplug for 5 minutes, then plug back in and restart. If H1 persists in a cool environment, the ambient sensor or control board may be faulty and should be tested as in the E1 procedure.
