Display shows P2; unit may continue to run fan but not cool.

Safety: Unplug the unit before cleaning or opening panels.

Steps:

• Check ambient temperature: Ensure the room temperature is within the operating range specified by NewAir (typically above ~61°F / 16°C for cooling).
• Clean filters and coils: Remove and wash the air filter. Inspect the evaporator coil for dust or ice buildup. Allow any ice to melt completely before restarting.
• Improve airflow: Make sure furniture or curtains are not blocking the intake or discharge vents.
• Sensor check: If P2 appears even in normal ambient conditions with clean filters, test the evaporator temperature sensor for proper resistance and replace if faulty.
• Restart: After corrections, plug the unit back in and restart in cooling mode. If P2 persists, the main control PCB may be misreading sensor data.
