Dehumidifier displays H1 and stops; may indicate a high temperature condition.

Safety first: Unplug the unit if any burning smell is present.

• Check room temperature: Ensure the room is below the maximum rated temperature (typically 95°F / 35°C). Move the unit to a cooler area if necessary.
• Improve ventilation: Provide at least 12 inches of clearance around all sides. Do not operate in a confined closet or near heat sources.
• Clean filter and coils: Wash the air filter and vacuum the condenser coil to improve heat dissipation.
• Sensor check: If H1 appears in a cool room, inspect and test the ambient temperature sensor and replace if faulty.
