Dehumidifier displays P2 and stops; unit may be in defrost or protection mode.

Safety: Unplug the unit if there is visible ice buildup.

Steps:

• Check room temperature: Ensure the room is within the operating range (typically above 5°C/41°F). Move the unit to a warmer area if needed.
• Inspect for ice: Remove the front cover and look at the evaporator coil. If iced over, allow it to thaw completely before restarting.
• Clean filter and coil: Wash the air filter and gently clean dust from the evaporator coil to improve airflow.
• Sensor check: Verify the defrost/coil sensor is firmly attached and wiring is intact. Replace the defrost sensor if readings are abnormal.
• Operation: After thawing and cleaning, plug in and allow the unit to run. P2 may clear automatically once coil temperature normalizes.
