What does p1 code mean?

The P1 error code indicates an abnormal increase or decrease in voltage. Check the cables in your air conditioning unit to ensure that the wires are not crossed or improperly connected. If the wires are properly connected, then check the power supply to ensure that the correct amount of voltage is going to the unit.
