LG portable air conditioner p2 error

If there is the P2 error on the display, please, check:

  1. Make sure the 2 wire, which connects the indoor and outdoor units, is not damaged. Check the circuit board in the indoor unit for blown fuses. Not unlikely, there is lack of voltage between the thermostat and heater.
  2. Drain water from the removable tank, which is located at the unit’s bottom, either on the right or left side of it.
