Airwell Overload / Overtemperature Protection

The indoor unit displays P2; the unit may stop; this is often associated with high temperature or overload.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Blocked coils, failed fan motor, high ambient temperature, overcharged refrigerant, faulty temperature sensor.

Safety: Turn off the power before inspection.

Steps:

1. Clean indoor and outdoor coils: Ensure both coils are free of dust and debris.
2. Check fan operation: Confirm both indoor and outdoor fans run properly.
3. Ensure ventilation: Make sure the outdoor unit has adequate clearance and is not installed in a confined space.
4. Professional check: If P2 persists, a technician should verify refrigerant charge and sensor readings.
