  High pressure is typically due to reduced condenser airflow. First, check for any obstructions in the ducting. Then, ensure proper ventilation for the condenser air system. Finally, inspect the condenser motors or blowers to confirm they are working correctly. The High Pressure (HP) switch needs to be manually reset by pressing the HP Reset button located in the condenser make-up air inlet on the back of the KPAC-II. You should feel a click when resetting it.
